description: Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
|

license: MIT
|

compatibility: Requires openspec CLI.

|
||||
Implement tasks from an OpenSpec change.
|
||||
|
||||
**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **Select the change**
|
||||
|
||||
If a name is provided, use it. Otherwise:
|
||||
- Infer from conversation context if the user mentioned a change
|
||||
- Auto-select if only one active change exists
|
||||
- If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
|
||||
|
||||
Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
|
||||
|
||||
2. **Check status to understand the schema**
|
||||
|
||||
```bash
|
||||
openspec status --change "<name>" --json
|
||||
```
|
||||
|
||||
Parse the JSON to understand:
|
||||
- `schemaName`: The workflow being used (e.g., "spec-driven")
|
||||
- Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
|
||||
|
||||
3. **Get apply instructions**
|
||||
|
||||
```bash
|
||||
openspec instructions apply --change "<name>" --json
|
||||
```
|
||||
|
||||
This returns:
|
||||
- Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
|
||||
- Progress (total, complete, remaining)
|
||||
- Task list with status
|
||||
- Dynamic instruction based on current state
|
||||
|
||||
**Handle states:**
|
||||
- If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
|
||||
- If `state: "all_done"`: congratulate, suggest archive
|
||||
- Otherwise: proceed to implementation
|
||||
|
||||
4. **Read context files**
|
||||
|
||||
Read the files listed in `contextFiles` from the apply instructions output.
|
||||
The files depend on the schema being used:
|
||||
- **spec-driven**: proposal, specs, design, tasks
|
||||
- Other schemas: follow the contextFiles from CLI output
|
||||
|
||||
5. **Show current progress**
|
||||
|
||||
Display:
|
||||
- Schema being used
|
||||
- Progress: "N/M tasks complete"
|
||||
- Remaining tasks overview
|
||||
- Dynamic instruction from CLI
|
||||
|
||||
6. **Implement tasks (loop until done or blocked)**
|
||||
|
||||
For each pending task:
|
||||
- Show which task is being worked on
|
||||
- Make the code changes required
|
||||
- Keep changes minimal and focused
|
||||
- Mark task complete in the tasks file: `- [ ]` → `- [x]`
|
||||
- Continue to next task
|
||||
|
||||
**Pause if:**
|
||||
- Task is unclear → ask for clarification
|
||||
- Implementation reveals a design issue → suggest updating artifacts
|
||||
- Error or blocker encountered → report and wait for guidance
|
||||
- User interrupts
|
||||
|
||||
7. **On completion or pause, show status**
|
||||
|
||||
Display:
|
||||
- Tasks completed this session
|
||||
- Overall progress: "N/M tasks complete"
|
||||
- If all done: suggest archive
|
||||
- If paused: explain why and wait for guidance
|
||||
|
||||
**Output During Implementation**
|
||||
|
||||
```
|
||||

2. <option 2>
|
||||
3. Other approach
|
||||
|
||||
What would you like to do?
|
||||
```
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Keep going through tasks until done or blocked
|
||||
- Always read context files before starting (from the apply instructions output)
|
||||
- If task is ambiguous, pause and ask before implementing
|
||||
- If implementation reveals issues, pause and suggest artifact updates
|
||||
- Keep code changes minimal and scoped to each task
|
||||
- Update task checkbox immediately after completing each task
|
||||
- Pause on errors, blockers, or unclear requirements - don't guess
|
||||
- Use contextFiles from CLI output, don't assume specific file names
|
||||
|
||||
**Fluid Workflow Integration**
|
||||
|
||||
This skill supports the "actions on a change" model:
|
||||
|
||||
- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
|
||||
- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

|
||||
Archive a completed change in the experimental workflow.
|
||||
|
||||
**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **If no change name provided, prompt for selection**
|
||||
|
||||
Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
|
||||
|
||||
Show only active changes (not already archived).
|
||||
Include the schema used for each change if available.
|
||||
|
||||
**IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
|
||||
|
||||
2. **Check artifact completion status**
|
||||
|
||||
Run `openspec status --change "<name>" --json` to check artifact completion.
|
||||
|
||||
Parse the JSON to understand:
|
||||
- `schemaName`: The workflow being used
|
||||
- `artifacts`: List of artifacts with their status (`done` or other)
|
||||
|
||||
**If any artifacts are not `done`:**
|
||||
- Display warning listing incomplete artifacts
|
||||
- Use **AskUserQuestion tool** to confirm user wants to proceed
|
||||
- Proceed if user confirms
|
||||
|
||||
3. **Check task completion status**
|
||||
|
||||
Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
|
||||
|
||||
Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
|
||||
|
||||
**If incomplete tasks found:**
|
||||
- Display warning showing count of incomplete tasks
|
||||
- Use **AskUserQuestion tool** to confirm user wants to proceed
|
||||
- Proceed if user confirms
|
||||
|
||||
**If no tasks file exists:** Proceed without task-related warning.
|
||||
|
||||
4. **Assess delta spec sync state**
|
||||
|
||||
Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
|
||||
|
||||
**If delta specs exist:**
|
||||
- Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
|
||||
- Determine what changes would be applied (adds, modifications, removals, renames)
|
||||
- Show a combined summary before prompting
|
||||
|
||||
**Prompt options:**
|
||||
- If changes needed: "Sync now (recommended)", "Archive without syncing"
|
||||
- If already synced: "Archive now", "Sync anyway", "Cancel"
|
||||
|
||||
If user chooses sync, execute /opsx:sync logic (use the openspec-sync-specs skill). Proceed to archive regardless of choice.
|
||||
|
||||
5. **Perform the archive**
|
||||
|
||||
Create the archive directory if it doesn't exist:
|
||||
|
||||
```bash
|
||||
mkdir -p openspec/changes/archive
|
||||
```
|
||||
|
||||
Generate target name using current date: `YYYY-MM-DD-<change-name>`
|
||||
|
||||
**Check if target already exists:**
|
||||
- If yes: Fail with error, suggest renaming existing archive or using different date
|
||||
- If no: Move the change directory to archive
|
||||
|
||||
```bash
|
||||
mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
|
||||
```
|
||||
|
||||
6. **Display summary**
|
||||
|
||||
Show archive completion summary including:
|
||||
- Change name
|
||||
- Schema that was used
|
||||
- Archive location
|
||||
- Whether specs were synced (if applicable)
|
||||
- Note about any warnings (incomplete artifacts/tasks)
|
||||
|
||||
**Output On Success**
|
||||
|
||||
```
|
||||
## Archive Complete
|
||||
|
||||
**Change:** <change-name>
|
||||
**Schema:** <schema-name>
|
||||
**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
|
||||
**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
|
||||
|
||||
All artifacts complete. All tasks complete.
|
||||
```
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Always prompt for change selection if not provided
|
||||
- Use artifact graph (openspec status --json) for completion checking
|
||||
- Don't block archive on warnings - just inform and confirm
|
||||
- Preserve .openspec.yaml when moving to archive (it moves with the directory)
|
||||
- Show clear summary of what happened
|
||||
- If sync is requested, use openspec-sync-specs approach (agent-driven)
|
||||
- If delta specs exist, always run the sync assessment and show the combined summary before prompting

Archive multiple completed changes in a single operation.
|
||||
|
||||
This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
|
||||
|
||||
**Input**: None required (prompts for selection)
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **Get active changes**
|
||||
|
||||
Run `openspec list --json` to get all active changes.
|
||||
|
||||
If no active changes exist, inform user and stop.
|
||||
|
||||
2. **Prompt for change selection**
|
||||
|
||||
Use **AskUserQuestion tool** with multi-select to let user choose changes:
|
||||
- Show each change with its schema
|
||||
- Include an option for "All changes"
|
||||
- Allow any number of selections (1+ works, 2+ is the typical use case)
|
||||
|
||||
**IMPORTANT**: Do NOT auto-select. Always let the user choose.
|
||||
|
||||
3. **Batch validation - gather status for all selected changes**
|
||||
|
||||
For each selected change, collect:
|
||||
|
||||
a. **Artifact status** - Run `openspec status --change "<name>" --json`
|
||||
- Parse `schemaName` and `artifacts` list
|
||||
- Note which artifacts are `done` vs other states
|
||||
|
||||
b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
|
||||
- Count `- [ ]` (incomplete) vs `- [x]` (complete)
|
||||
- If no tasks file exists, note as "No tasks"
|
||||
|
||||
c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
|
||||
- List which capability specs exist
|
||||
- For each, extract requirement names (lines matching `### Requirement: <name>`)
|
||||
|
||||
4. **Detect spec conflicts**
|
||||
|
||||
Build a map of `capability -> [changes that touch it]`:
|
||||
|
||||
```
|
||||
auth -> [change-a, change-b] <- CONFLICT (2+ changes)
|
||||
api -> [change-c] <- OK (only 1 change)
|
||||
```
|
||||
|
||||
A conflict exists when 2+ selected changes have delta specs for the same capability.
|
||||
|
||||
5. **Resolve conflicts agentically**
|
||||
|
||||
**For each conflict**, investigate the codebase:
|
||||
|
||||
a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
|
||||
|
||||
b. **Search the codebase** for implementation evidence:
|
||||
- Look for code implementing requirements from each delta spec
|
||||
- Check for related files, functions, or tests
|
||||
|
||||
c. **Determine resolution**:
|
||||
- If only one change is actually implemented -> sync that one's specs
|
||||
- If both implemented -> apply in chronological order (older first, newer overwrites)
|
||||
- If neither implemented -> skip spec sync, warn user
|
||||
|
||||
d. **Record resolution** for each conflict:
|
||||
- Which change's specs to apply
|
||||
- In what order (if both)
|
||||
- Rationale (what was found in codebase)
|
||||
|
||||
6. **Show consolidated status table**
|
||||
|
||||
Display a table summarizing all changes:
|
||||
|
||||
```
|
||||
| Change | Artifacts | Tasks | Specs | Conflicts | Status |
|
||||
|---------------------|-----------|-------|---------|-----------|--------|
|
||||
| schema-management | Done | 5/5 | 2 delta | None | Ready |
|
||||
| project-config | Done | 3/3 | 1 delta | None | Ready |
|
||||
| add-oauth | Done | 4/4 | 1 delta | auth (!) | Ready* |
|
||||
| add-verify-skill | 1 left | 2/5 | None | None | Warn |
|
||||
```
|
||||
|
||||
For conflicts, show the resolution:
|
||||
|
||||
```
|
||||
* Conflict resolution:
|
||||
- auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
|
||||
```
|
||||
|
||||
For incomplete changes, show warnings:
|
||||
|
||||
```
|
||||
Warnings:
|
||||
- add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
|
||||
```
|
||||
|
||||
7. **Confirm batch operation**
|
||||
|
||||
Use **AskUserQuestion tool** with a single confirmation:
|
||||
- "Archive N changes?" with options based on status
|
||||
- Options might include:
|
||||
- "Archive all N changes"
|
||||
- "Archive only N ready changes (skip incomplete)"
|
||||
- "Cancel"
|
||||
|
||||
If there are incomplete changes, make clear they'll be archived with warnings.
|
||||
|
||||
8. **Execute archive for each confirmed change**
|
||||
|
||||
Process changes in the determined order (respecting conflict resolution):
|
||||
|
||||
a. **Sync specs** if delta specs exist:
|
||||
- Use the openspec-sync-specs approach (agent-driven intelligent merge)
|
||||
- For conflicts, apply in resolved order
|
||||
- Track if sync was done
|
||||
|
||||
b. **Perform the archive**:
|
||||
|
||||
```bash
|
||||
mkdir -p openspec/changes/archive
|
||||
mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
|
||||
```
|
||||
|
||||
c. **Track outcome** for each change:
|
||||
- Success: archived successfully
|
||||
- Failed: error during archive (record error)
|
||||
- Skipped: user chose not to archive (if applicable)
|
||||
|
||||
9. **Display summary**
|
||||
|
||||
Show final results:
|
||||
|
||||
```
|
||||

**Conflict Resolution Examples**
|
||||
|
||||
Example 1: Only one implemented
|
||||
|
||||
```
|
||||
Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
|
||||
|
||||
Checking add-oauth:
|
||||
- Delta adds "OAuth Provider Integration" requirement
|
||||
- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
|
||||
|
||||
Checking add-jwt:
|
||||
- Delta adds "JWT Token Handling" requirement
|
||||
- Searching codebase... no JWT implementation found
|
||||
|
||||
Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
|
||||
```
|
||||
|
||||
Example 2: Both implemented
|
||||
|
||||
```
|
||||
Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
|
||||
|
||||
Checking add-rest-api (created 2026-01-10):
|
||||
- Delta adds "REST Endpoints" requirement
|
||||
- Searching codebase... found src/api/rest.ts
|
||||
|
||||
Checking add-graphql (created 2026-01-15):
|
||||
- Delta adds "GraphQL Schema" requirement
|
||||
- Searching codebase... found src/api/graphql.ts
|
||||
|
||||
Resolution: Both implemented. Will apply add-rest-api specs first,
|
||||
then add-graphql specs (chronological order, newer takes precedence).
|
||||
```
|
||||
|
||||
**Output On Success**

```
|
||||
## No Changes to Archive
|
||||
|
||||
No active changes found. Use `/opsx:new` to create a new change.
|
||||
```
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Allow any number of changes (1+ is fine, 2+ is the typical use case)
|
||||
- Always prompt for selection, never auto-select
|
||||
- Detect spec conflicts early and resolve by checking codebase
|
||||
- When both changes are implemented, apply specs in chronological order
|
||||
- Skip spec sync only when implementation is missing (warn user)
|
||||
- Show clear per-change status before confirming
|
||||
- Use single confirmation for entire batch
|
||||
- Track and report all outcomes (success/skip/fail)
|
||||
- Preserve .openspec.yaml when moving to archive
|
||||
- Archive directory target uses current date: YYYY-MM-DD-<name>
|
||||
- If archive target exists, fail that change but continue with others

Continue working on a change by creating the next artifact.
|
||||
|
||||
**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **If no change name provided, prompt for selection**
|
||||
|
||||
Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
|
||||
|
||||
Present the top 3-4 most recently modified changes as options, showing:
|
||||
- Change name
|
||||
- Schema (from `schema` field if present, otherwise "spec-driven")
|
||||
- Status (e.g., "0/5 tasks", "complete", "no tasks")
|
||||
- How recently it was modified (from `lastModified` field)
|
||||
|
||||
Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
|
||||
|
||||
**IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
|
||||
|
||||
2. **Check current status**
|
||||
|
||||
```bash
|
||||
openspec status --change "<name>" --json
|
||||
```
|
||||
|
||||
Parse the JSON to understand current state. The response includes:
|
||||
- `schemaName`: The workflow schema being used (e.g., "spec-driven")
|
||||
- `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
|
||||
- `isComplete`: Boolean indicating if all artifacts are complete
|
||||
|
||||
3. **Act based on status**:
|
||||
|
||||
***
|
||||
|
||||
**If all artifacts are complete (`isComplete: true`)**:
|
||||
- Congratulate the user
|
||||
- Show final status including the schema used
|
||||
- Suggest: "All artifacts created! You can now implement this change or archive it."
|
||||
- STOP
|
||||
|
||||
***
|
||||
|
||||
**If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
|
||||
- Pick the FIRST artifact with `status: "ready"` from the status output
|
||||
- Get its instructions:
|
||||
```bash
|
||||
openspec instructions <artifact-id> --change "<name>" --json
|
||||
```
|
||||
- Parse the JSON. The key fields are:
|
||||
- `context`: Project background (constraints for you - do NOT include in output)
|
||||
- `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
|
||||
- `template`: The structure to use for your output file
|
||||
- `instruction`: Schema-specific guidance
|
||||
- `outputPath`: Where to write the artifact
|
||||
- `dependencies`: Completed artifacts to read for context
|
||||
- **Create the artifact file**:
|
||||
- Read any completed dependency files for context
|
||||
- Use `template` as the structure - fill in its sections
|
||||
- Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
|
||||
- Write to the output path specified in instructions
|
||||
- Show what was created and what's now unlocked
|
||||
- STOP after creating ONE artifact
|
||||
|
||||
***
|
||||
|
||||
**If no artifacts are ready (all blocked)**:
|
||||
- This shouldn't happen with a valid schema
|
||||
- Show status and suggest checking for issues
|
||||
|
||||
4. **After creating an artifact, show progress**
|
||||
```bash
|
||||
openspec status --change "<name>"
|
||||
```
|
||||
|
||||
**Output**
|
||||
|
||||
After each invocation, show:
|
||||
|
||||
- Which artifact was created
|
||||
- Schema workflow being used
|
||||
- Current progress (N/M complete)
|
||||
- What artifacts are now unlocked
|
||||
- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
|
||||
|
||||
**Artifact Creation Guidelines**
|
||||
|
||||
The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
|
||||
|
||||
Common artifact patterns:
|
||||
|
||||
**spec-driven schema** (proposal → specs → design → tasks):
|
||||
|
||||
- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
|
||||
- The Capabilities section is critical - each capability listed will need a spec file.
|
||||
- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
|
||||
- **design.md**: Document technical decisions, architecture, and implementation approach.
|
||||
- **tasks.md**: Break down implementation into checkboxed tasks.
|
||||
|
||||
For other schemas, follow the `instruction` field from the CLI output.
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Create ONE artifact per invocation
|
||||
- Always read dependency artifacts before creating a new one
|
||||
- Never skip artifacts or create out of order
|
||||
- If context is unclear, ask the user before creating
|
||||
- Verify the artifact file exists after writing before marking progress
|
||||
- Use the schema's artifact sequence, don't assume specific artifact names
|
||||
- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
|
||||
- Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
|
||||
- These guide what you write, but should never appear in the output

Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
|
||||
|
||||
**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.

**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
|

|
||||
|
||||
## The Stance
|
||||
|
||||
- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
|
||||
- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
|
||||
- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
|
||||
- **Adaptive** - Follow interesting threads, pivot when new information emerges
|
||||
- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
|
||||
- **Grounded** - Explore the actual codebase when relevant, don't just theorize

## What You Might Do
|
||||
|
||||
Depending on what the user brings, you might:
|
||||
|
||||
**Explore the problem space**
|
||||
|
||||
- Ask clarifying questions that emerge from what they said
|
||||
- Challenge assumptions
|
||||
- Reframe the problem
|
||||
- Find analogies
|
||||
|
||||
**Investigate the codebase**
|
||||
|
||||
- Map existing architecture relevant to the discussion
|
||||
- Find integration points
|
||||
- Identify patterns already in use
|
||||
- Surface hidden complexity
|
||||
|
||||
**Compare options**
|
||||
|
||||
- Brainstorm multiple approaches
|
||||
- Build comparison tables
|
||||
- Sketch tradeoffs
|
||||
- Recommend a path (if asked)
|
||||
|
||||
**Visualize**

|

## OpenSpec Awareness
|
||||
|
||||
You have full context of the OpenSpec system. Use it naturally, don't force it.
|
||||
|
||||
### Check for context
|
||||
|
||||
At the start, quickly check what exists:
|
||||
|
||||
```bash
|
||||
openspec list --json
|
||||
```
|
||||
|
||||
This tells you:
|
||||
|
||||
- If there are active changes
|
||||
- Their names, schemas, and status
|
||||
- What the user might be working on
|
||||
|
||||
### When no change exists
|
||||
|
||||
Think freely. When insights crystallize, you might offer:
|
||||
|
||||
- "This feels solid enough to start a change. Want me to create one?"
|
||||
→ Can transition to `/opsx:new` or `/opsx:ff`
|
||||
- Or keep exploring - no pressure to formalize
|
||||
|
||||
### When a change exists
|
||||
|
||||
If the user mentions a change or you detect one is relevant:
|
||||
|
||||
1. **Read existing artifacts for context**
|
||||
- `openspec/changes/<name>/proposal.md`
|
||||
- `openspec/changes/<name>/design.md`
|
||||
- `openspec/changes/<name>/tasks.md`
|
||||
- etc.
|
||||
|
||||
2. **Reference them naturally in conversation**
|
||||
- "Your design mentions using Redis, but we just realized SQLite fits better..."
|
||||
- "The proposal scopes this to premium users, but we're now thinking everyone..."
|
||||
|
||||
3. **Offer to capture when decisions are made**
|
||||
|
||||
| Insight Type | Where to Capture |
|
||||
| -------------------------- | ---------------------------- |
|
||||
| New requirement discovered | `specs/<capability>/spec.md` |
|
||||
| Requirement changed | `specs/<capability>/spec.md` |
|
||||
| Design decision made | `design.md` |
|
||||
| Scope changed | `proposal.md` |
|
||||
| New work identified | `tasks.md` |
|
||||
| Assumption invalidated | Relevant artifact |
|
||||
|
||||
Example offers:
|
||||
- "That's a design decision. Capture it in design.md?"
|
||||
- "This is a new requirement. Add it to specs?"
|
||||
- "This changes scope. Update the proposal?"
|
||||
|
||||
4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
|
||||

|
||||
|
||||
## What You Don't Have To Do
|
||||
|
||||
- Follow a script
|
||||
- Ask the same questions every time
|
||||
- Produce a specific artifact
|
||||
- Reach a conclusion
|
||||

**User is stuck mid-implementation:**

```
|

User: /opsx:explore add-auth-system

The OAuth integration is more complex than expected
|

You: [reads change artifacts]
|

You're on task 4: "Implement OAuth flow"
|

Let me trace what's involved...
|
||||

[draws diagram, explores options, suggests paths]
|

Want to update the design to reflect this?

Or add a spike task to investigate?

|

|

**User wants to compare options:**
|

```
|

User: Should we use Postgres or SQLite?
|

## Ending Discovery
|
||||
|
||||
There's no required ending. Discovery might:
|
||||
|
||||
- **Flow into action**: "Ready to start? /opsx:new or /opsx:ff"
|
||||
- **Result in artifact updates**: "Updated design.md with these decisions"
|
||||
- **Just provide clarity**: User has what they need, moves on
|
||||
- **Continue later**: "We can pick this up anytime"
|
||||
|
||||
When it feels like things are crystallizing, you might summarize:
|
||||
|
||||
```
|
||||
## What We Figured Out
|
||||
|
||||
**The problem**: [crystallized understanding]
|
||||
|
||||
**The approach**: [if one emerged]
|
||||
|
||||
**Open questions**: [if any remain]
|
||||
|
||||
**Next steps** (if ready):
|
||||
- Create a change: /opsx:new <name>
|
||||
- Fast-forward to tasks: /opsx:ff <name>
|
||||
- Keep exploring: just keep talking
|
||||
```
|
||||
|
||||
But this summary is optional. Sometimes the thinking IS the value.

|

|
||||
## Guardrails
|
||||
|
||||
- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
|
||||
- **Don't fake understanding** - If something is unclear, dig deeper
|
||||
- **Don't rush** - Discovery is thinking time, not task time
|
||||
- **Don't force structure** - Let patterns emerge naturally
|
||||
- **Don't auto-capture** - Offer to save insights, don't just do it
|
||||
- **Do visualize** - A good diagram is worth many paragraphs
|
||||
- **Do explore the codebase** - Ground discussions in reality
|
||||
- **Do question assumptions** - Including the user's and your own

Fast-forward through artifact creation - generate everything needed to start implementation in one go.
|
||||
|
||||
**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **If no clear input provided, ask what they want to build**
|
||||
|
||||
Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
|
||||
|
||||
> "What change do you want to work on? Describe what you want to build or fix."
|
||||
|
||||
From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
|
||||
|
||||
**IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
|
||||
|
||||
2. **Create the change directory**
|
||||
|
||||
```bash
|
||||
openspec new change "<name>"
|
||||
```
|
||||
|
||||
This creates a scaffolded change at `openspec/changes/<name>/`.
|
||||
|
||||
3. **Get the artifact build order**
|
||||
|
||||
```bash
|
||||
openspec status --change "<name>" --json
|
||||
```
|
||||
|
||||
Parse the JSON to get:
|
||||
- `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
|
||||
- `artifacts`: list of all artifacts with their status and dependencies
|
||||
|
||||
4. **Create artifacts in sequence until apply-ready**
|
||||
|
||||
Use the **TodoWrite tool** to track progress through the artifacts.
|
||||
|
||||
Loop through artifacts in dependency order (artifacts with no pending dependencies first):
|
||||
|
||||
a. **For each artifact that is `ready` (dependencies satisfied)**:
|
||||
- Get instructions:
|
||||
```bash
|
||||
openspec instructions <artifact-id> --change "<name>" --json
|
||||
```
|
||||
- The instructions JSON includes:
|
||||
- `context`: Project background (constraints for you - do NOT include in output)
|
||||
- `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
|
||||
- `template`: The structure to use for your output file
|
||||
- `instruction`: Schema-specific guidance for this artifact type
|
||||
- `outputPath`: Where to write the artifact
|
||||
- `dependencies`: Completed artifacts to read for context
|
||||
- Read any completed dependency files for context
|
||||
- Create the artifact file using `template` as the structure
|
||||
- Apply `context` and `rules` as constraints - but do NOT copy them into the file
|
||||
- Show brief progress: "✓ Created <artifact-id>"
|
||||
|
||||
b. **Continue until all `applyRequires` artifacts are complete**
|
||||
- After creating each artifact, re-run `openspec status --change "<name>" --json`
|
||||
- Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
|
||||
- Stop when all `applyRequires` artifacts are done
|
||||
|
||||
c. **If an artifact requires user input** (unclear context):
|
||||
- Use **AskUserQuestion tool** to clarify
|
||||
- Then continue with creation
|
||||
|
||||
5. **Show final status**
|
||||
```bash
|
||||
openspec status --change "<name>"
|
||||
```
|
||||
|
||||
**Output**
|
||||
|
||||
After completing all artifacts, summarize:
|
||||
|
||||
- Change name and location
|
||||
- List of artifacts created with brief descriptions
|
||||
- What's ready: "All artifacts created! Ready for implementation."
|
||||
- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
|
||||
|
||||
**Artifact Creation Guidelines**
|
||||
|
||||
- Follow the `instruction` field from `openspec instructions` for each artifact type
|
||||
- The schema defines what each artifact should contain - follow it
|
||||
- Read dependency artifacts for context before creating new ones
|
||||
- Use `template` as the structure for your output file - fill in its sections
|
||||
- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
|
||||
- Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
|
||||
- These guide what you write, but should never appear in the output
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
|
||||
- Always read dependency artifacts before creating a new one
|
||||
- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
|
||||
- If a change with that name already exists, suggest continuing that change instead
|
||||
- Verify each artifact file exists after writing before proceeding to next

|

Start a new change using the experimental artifact-driven approach.
|
||||
|
||||
**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **If no clear input provided, ask what they want to build**
|
||||
|
||||
Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
|
||||
|
||||
> "What change do you want to work on? Describe what you want to build or fix."
|
||||
|
||||
From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
|
||||
|
||||
**IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
|
||||
|
||||
2. **Determine the workflow schema**
|
||||
|
||||
Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
|
||||
|
||||
**Use a different schema only if the user mentions:**
|
||||
- A specific schema name → use `--schema <name>`
|
||||
- "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
|
||||
|
||||
**Otherwise**: Omit `--schema` to use the default.
|
||||
|
||||
3. **Create the change directory**
|
||||
|
||||
```bash
|
||||
openspec new change "<name>"
|
||||
```
|
||||
|
||||
Add `--schema <name>` only if the user requested a specific workflow.
|
||||
This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
|
||||
|
||||
4. **Show the artifact status**
|
||||
|
||||
```bash
|
||||
openspec status --change "<name>"
|
||||
```
|
||||
|
||||
This shows which artifacts need to be created and which are ready (dependencies satisfied).
|
||||
|
||||
5. **Get instructions for the first artifact**
|
||||
The first artifact depends on the schema (e.g., `proposal` for spec-driven).
|
||||
Check the status output to find the first artifact with status "ready".
|
||||
|
||||
```bash
|
||||
openspec instructions <first-artifact-id> --change "<name>"
|
||||
```
|
||||
|
||||
This outputs the template and context for creating the first artifact.
|
||||
|
||||
6. **STOP and wait for user direction**
|
||||
|
||||
**Output**
|
||||
|
||||
After completing the steps, summarize:
|
||||
|
||||
- Change name and location
|
||||
- Schema/workflow being used and its artifact sequence
|
||||
- Current status (0/N artifacts complete)
|
||||
- The template for the first artifact
|
||||
- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Do NOT create any artifacts yet - just show the instructions
|
||||
- Do NOT advance beyond showing the first artifact template
|
||||
- If the name is invalid (not kebab-case), ask for a valid name
|
||||
- If a change with that name already exists, suggest continuing that change instead
|
||||
- Pass --schema if using a non-default workflow

## Welcome to OpenSpec!
|
||||
|
||||
I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
|
||||
|
||||
**What we'll do:**
|
||||
1. Pick a small, real task in your codebase
|
||||
2. Explore the problem briefly
|
||||
3. Create a change (the container for our work)
|
||||
4. Build the artifacts: proposal → specs → design → tasks
|
||||
5. Implement the tasks
|
||||
6. Archive the completed change
|
||||
|
||||
**Time:** ~15-20 minutes
|
||||
|
||||
Let's start by finding something to work on.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 2: Task Selection
|
||||
|
||||
### Codebase Analysis
|
||||
|
||||
Scan the codebase for small improvement opportunities. Look for:
|
||||
|
||||
1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
|
||||
2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
|
||||
3. **Functions without tests** - Cross-reference `src/` with test directories
|
||||
4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
|
||||
5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
|
||||
6. **Missing validation** - User input handlers without validation
|
||||
|
||||
Also check recent git activity:
|
||||
|
||||
```bash
|
||||
git log --oneline -10 2>/dev/null || echo "No git history"
|
||||
```
|
||||
|
||||
### Present Suggestions
|
||||
|
||||
From your analysis, present 3-4 specific suggestions:
|
||||
|
||||
```
|
||||
## Task Suggestions
|
||||
|
||||
Based on scanning your codebase, here are some good starter tasks:
|
||||
|
||||
**1. [Most promising task]**
|
||||
Location: `src/path/to/file.ts:42`
|
||||
Scope: ~1-2 files, ~20-30 lines
|
||||
Why it's good: [brief reason]
|
||||
|
||||
**2. [Second task]**
|
||||
Location: `src/another/file.ts`
|
||||
Scope: ~1 file, ~15 lines
|
||||
Why it's good: [brief reason]
|
||||
|
||||
**3. [Third task]**
|
||||
Location: [location]
|
||||
Scope: [estimate]
|
||||
Why it's good: [brief reason]
|
||||
|
||||
**4. Something else?**
|
||||
Tell me what you'd like to work on.
|
||||
|
||||
Which task interests you? (Pick a number or describe your own)
|
||||
```
|
||||
|
||||
**If nothing found:** Fall back to asking what the user wants to build:
|
||||
|
||||
> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
|
||||
|
||||
### Scope Guardrail
|
||||
|
||||
If the user picks or describes something too large (major feature, multi-day work):
|
||||
|
||||
```
|
||||
That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
|
||||
|
||||
For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
|
||||
|
||||
**Options:**
|
||||
1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
|
||||
2. **Pick something else** - One of the other suggestions, or a different small task?
|
||||
3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
|
||||
|
||||
What would you prefer?
|
||||
```
|
||||
|
||||
Let the user override if they insist—this is a soft guardrail.
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: Explore Demo
|
||||
|
||||
Once a task is selected, briefly demonstrate explore mode:
|
||||
|
||||
```
|
||||
Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
|
||||
```
|
||||
|
||||
Spend 1-2 minutes investigating the relevant code:
|
||||
|
||||
- Read the file(s) involved
|
||||
- Draw a quick ASCII diagram if it helps
|
||||
- Note any considerations
|
||||
|
||||
```
|
||||
## Quick Exploration
|
||||
|
||||
[Your brief analysis—what you found, any considerations]
|
||||
|
||||
┌─────────────────────────────────────────┐
|
||||
│ [Optional: ASCII diagram if helpful] │
|
||||
└─────────────────────────────────────────┘
|
||||
|
||||
Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
|
||||
|
||||
Now let's create a change to hold our work.
|
||||
```
|
||||
|
||||
**PAUSE** - Wait for user acknowledgment before proceeding.
|
||||
|
||||
---
|
||||
|
||||
## Phase 4: Create the Change
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## Creating a Change
|
||||
|
||||
A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
|
||||
|
||||
Let me create one for our task.
|
||||
```
|
||||
|
||||
**DO:** Create the change with a derived kebab-case name:
|
||||
|
||||
```bash
|
||||
openspec new change "<derived-name>"
|
||||
```
|
||||
|
||||
**SHOW:**
|
||||
|
||||
```
|
||||
Created: `openspec/changes/<name>/`
|
||||
|
||||
The folder structure:
|
||||
```
|
||||
|
||||
openspec/changes/<name>/
|
||||
├── proposal.md ← Why we're doing this (empty, we'll fill it)
|
||||

|

Now let's fill in the first artifact—the proposal.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Proposal
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## The Proposal
|
||||
|
||||
The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
|
||||
|
||||
I'll draft one based on our task.
|
||||
```
|
||||
|
||||
**DO:** Draft the proposal content (don't save yet):
|
||||
|
||||
```
|
||||
Here's a draft proposal:
|
||||
|
||||
---
|
||||
|
||||
## Why
|
||||
|
||||
[1-2 sentences explaining the problem/opportunity]
|
||||
|
||||
## What Changes
|
||||
|
||||
[Bullet points of what will be different]
|
||||
|
||||
## Capabilities
|
||||
|
||||
### New Capabilities
|
||||
- `<capability-name>`: [brief description]
|
||||
|
||||
### Modified Capabilities
|
||||
<!-- If modifying existing behavior -->
|
||||
|
||||
## Impact
|
||||
|
||||
- `src/path/to/file.ts`: [what changes]
|
||||
- [other files if applicable]
|
||||
|
||||
---
|
||||
|
||||
Does this capture the intent? I can adjust before we save it.
|
||||
```
|
||||
|
||||
**PAUSE** - Wait for user approval/feedback.
|
||||
|
||||
After approval, save the proposal:
|
||||
|
||||
```bash
|
||||
openspec instructions proposal --change "<name>" --json
|
||||
```
|
||||
|
||||
Then write the content to `openspec/changes/<name>/proposal.md`.
|
||||
|
||||
```
|
||||
Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
|
||||
|
||||
Next up: specs.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 6: Specs
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## Specs
|
||||
|
||||
Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
|
||||
|
||||
For a small task like this, we might only need one spec file.
|
||||
```
|
||||
|
||||
**DO:** Create the spec file:
|
||||
|
||||
```bash
|
||||
mkdir -p openspec/changes/<name>/specs/<capability-name>
|
||||
```
|
||||
|
||||
Draft the spec content:
|
||||
|
||||
```
|
||||
Here's the spec:
|
||||
|
||||
---
|
||||
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: <Name>
|
||||
|
||||
<Description of what the system should do>
|
||||
|
||||
#### Scenario: <Scenario name>
|
||||
|
||||
- **WHEN** <trigger condition>
|
||||
- **THEN** <expected outcome>
|
||||
- **AND** <additional outcome if needed>
|
||||
|
||||
---
|
||||
|
||||
This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
|
||||
```
|
||||
|
||||
Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
|
||||
|
||||
---
|
||||
|
||||
## Phase 7: Design
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## Design
|
||||
|
||||
The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
|
||||
|
||||
For small changes, this might be brief. That's fine—not every change needs deep design discussion.
|
||||
```
|
||||
|
||||
**DO:** Draft design.md:
|
||||
|
||||
```
|
||||
Here's the design:
|
||||
|
||||
---
|
||||
|
||||
## Context
|
||||
|
||||
[Brief context about the current state]
|
||||
|
||||
## Goals / Non-Goals
|
||||
|
||||
**Goals:**
|
||||
- [What we're trying to achieve]
|
||||
|
||||
**Non-Goals:**
|
||||
- [What's explicitly out of scope]
|
||||
|
||||
## Decisions
|
||||
|
||||
### Decision 1: [Key decision]
|
||||
|
||||
[Explanation of approach and rationale]
|
||||
|
||||
---
|
||||
|
||||
For a small task, this captures the key decisions without over-engineering.
|
||||
```
|
||||
|
||||
Save to `openspec/changes/<name>/design.md`.
|
||||
|
||||
---
|
||||
|
||||
## Phase 8: Tasks
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## Tasks
|
||||
|
||||
Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
|
||||
|
||||
These should be small, clear, and in logical order.
|
||||
```
|
||||
|
||||
**DO:** Generate tasks based on specs and design:
|
||||
|
||||
```
|
||||
Here are the implementation tasks:
|
||||
|
||||
---
|
||||
|
||||
## 1. [Category or file]
|
||||
|
||||
- [ ] 1.1 [Specific task]
|
||||
- [ ] 1.2 [Specific task]
|
||||
|
||||
## 2. Verify
|
||||
|
||||
- [ ] 2.1 [Verification step]
|
||||
|
||||
---
|
||||
|
||||
Each checkbox becomes a unit of work in the apply phase. Ready to implement?
|
||||
```
|
||||
|
||||
**PAUSE** - Wait for user to confirm they're ready to implement.
|
||||
|
||||
Save to `openspec/changes/<name>/tasks.md`.
|
||||
|
||||
---
|
||||
|
||||
## Phase 9: Apply (Implementation)
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## Implementation
|
||||
|
||||
Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
|
||||
```
|
||||
|
||||
**DO:** For each task:
|
||||
|
||||
1. Announce: "Working on task N: [description]"
|
||||
2. Implement the change in the codebase
|
||||
3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
|
||||
4. Mark complete in tasks.md: `- [ ]` → `- [x]`
|
||||
5. Brief status: "✓ Task N complete"
|
||||
|
||||
Keep narration light—don't over-explain every line of code.
|
||||
|
||||
After all tasks:
|
||||
|
||||
```
|
||||
## Implementation Complete
|
||||
|
||||
All tasks done:
|
||||
- [x] Task 1
|
||||
- [x] Task 2
|
||||
- [x] ...
|
||||
|
||||
The change is implemented! One more step—let's archive it.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 10: Archive
|
||||
|
||||
**EXPLAIN:**
|
||||
|
||||
```
|
||||
## Archiving
|
||||
|
||||
When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
|
||||
|
||||
Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
|
||||
```
|
||||
|
||||
**DO:**
|
||||
|
||||
```bash
|
||||
openspec archive "<name>"
|
||||
```
|
||||
|
||||
**SHOW:**
|
||||
|
||||
```
|
||||
Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
|
||||
|
||||
The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Phase 11: Recap & Next Steps
|
||||
|
||||
```
|
||||
## Congratulations!
|
||||
|
||||
You just completed a full OpenSpec cycle:
|
||||
|
||||
1. **Explore** - Thought through the problem
|
||||
2. **New** - Created a change container
|
||||
3. **Proposal** - Captured WHY
|
||||
4. **Specs** - Defined WHAT in detail
|
||||
5. **Design** - Decided HOW
|
||||
6. **Tasks** - Broke it into steps
|
||||
7. **Apply** - Implemented the work
|
||||
8. **Archive** - Preserved the record
|
||||
|
||||
This same rhythm works for any size change—a small fix or a major feature.

## Command Reference
|
||||
|
||||
| Command | What it does |
|
||||
|---------|--------------|
|
||||
| `/opsx:explore` | Think through problems before/during work |
|
||||
| `/opsx:new` | Start a new change, step through artifacts |
|
||||
| `/opsx:ff` | Fast-forward: create all artifacts at once |
|
||||
| `/opsx:continue` | Continue working on an existing change |
|
||||
| `/opsx:apply` | Implement tasks from a change |
|
||||
| `/opsx:verify` | Verify implementation matches artifacts |
|
||||
| `/opsx:archive` | Archive a completed change |
|
||||
|
||||
---
|
||||
|
||||
## What's Next?
|
||||
|
||||
Try `/opsx:new` or `/opsx:ff` on something you actually want to build. You've got the rhythm now!

## Graceful Exit Handling
|
||||
|
||||
### User wants to stop mid-way
|
||||
|
||||
If the user says they need to stop, want to pause, or seem disengaged:
|
||||
|
||||
```
|
||||
No problem! Your change is saved at `openspec/changes/<name>/`.
|
||||
|
||||
To pick up where we left off later:
|
||||
- `/opsx:continue <name>` - Resume artifact creation
|
||||
- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
|
||||
|
||||
The work won't be lost. Come back whenever you're ready.
|
||||
```
|
||||
|
||||
Exit gracefully without pressure.
|
||||
|
||||
### User just wants command reference
|
||||
|
||||
If the user says they just want to see the commands or skip the tutorial:
|
||||
|
||||
```
|
||||
## OpenSpec Quick Reference
|
||||
|
||||
| Command | What it does |
|
||||
|---------|--------------|
|
||||
| `/opsx:explore` | Think through problems (no code changes) |
|
||||
| `/opsx:new <name>` | Start a new change, step by step |
|
||||
| `/opsx:ff <name>` | Fast-forward: all artifacts at once |

|
||||
```
|
||||
|
||||
Exit gracefully.

|
||||
|
||||
## Guardrails
|
||||
|
||||
- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
|
||||
- **Keep narration light** during implementation—teach without lecturing
|
||||
- **Don't skip phases** even if the change is small—the goal is teaching the workflow
|
||||
- **Pause for acknowledgment** at marked points, but don't over-pause
|
||||
- **Handle exits gracefully**—never pressure the user to continue
|
||||
- **Use real codebase tasks**—don't simulate or use fake examples
|
||||
- **Adjust scope gently**—guide toward smaller tasks but respect user choice

Sync delta specs from a change to main specs.
|
||||
|
||||
This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
|
||||
|
||||
**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **If no change name provided, prompt for selection**
|
||||
|
||||
Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
|
||||
|
||||
Show changes that have delta specs (under `specs/` directory).
|
||||
|
||||
**IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
|
||||
|
||||
2. **Find delta specs**
|
||||
|
||||
Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
|
||||
|
||||
Each delta spec file contains sections like:
|
||||
- `## ADDED Requirements` - New requirements to add
|
||||
- `## MODIFIED Requirements` - Changes to existing requirements
|
||||
- `## REMOVED Requirements` - Requirements to remove
|
||||
- `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
|
||||
|
||||
If no delta specs found, inform user and stop.
|
||||
|
||||
3. **For each delta spec, apply changes to main specs**
|
||||
|
||||
For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
|
||||
|
||||
a. **Read the delta spec** to understand the intended changes
|
||||
|
||||
b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
|
||||
|
||||
c. **Apply changes intelligently**:
|
||||
|
||||
**ADDED Requirements:**
|
||||
- If requirement doesn't exist in main spec → add it
|
||||
- If requirement already exists → update it to match (treat as implicit MODIFIED)
|
||||
|
||||
**MODIFIED Requirements:**
|
||||
- Find the requirement in main spec
|
||||
- Apply the changes - this can be:
|
||||
- Adding new scenarios (don't need to copy existing ones)
|
||||
- Modifying existing scenarios
|
||||
- Changing the requirement description
|
||||
- Preserve scenarios/content not mentioned in the delta
|
||||
|
||||
**REMOVED Requirements:**
|
||||
- Remove the entire requirement block from main spec
|
||||
|
||||
**RENAMED Requirements:**
|
||||
- Find the FROM requirement, rename to TO
|
||||
|
||||
d. **Create new main spec** if capability doesn't exist yet:
|
||||
- Create `openspec/specs/<capability>/spec.md`
|
||||
- Add Purpose section (can be brief, mark as TBD)
|
||||
- Add Requirements section with the ADDED requirements
|
||||
|
||||
4. **Show summary**
|
||||
|
||||
After applying all changes, summarize:
|
||||
- Which capabilities were updated
|
||||
- What changes were made (requirements added/modified/removed/renamed)
|
||||
|
||||
**Delta Spec Format Reference**
|
||||
|
||||
```markdown
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: New Feature
|
||||
|
||||
The system SHALL do something new.
|
||||
|
||||
#### Scenario: Basic case
|
||||
|
||||
- **WHEN** user does X
|
||||
- **THEN** system does Y
|
||||
|
||||
## MODIFIED Requirements
|
||||
|
||||
### Requirement: Existing Feature
|
||||
|
||||
#### Scenario: New scenario to add
|
||||
|
||||
- **WHEN** user does A
|
||||
- **THEN** system does B
|
||||
|
||||
## REMOVED Requirements
|
||||
|
||||
### Requirement: Deprecated Feature
|
||||
|
||||
## RENAMED Requirements
|
||||
|
||||
- FROM: `### Requirement: Old Name`
|
||||
- TO: `### Requirement: New Name`
|
||||
```
|
||||
|
||||
**Key Principle: Intelligent Merging**
|
||||
|
||||
Unlike programmatic merging, you can apply **partial updates**:
|
||||
|
||||
- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
|
||||
- The delta represents _intent_, not a wholesale replacement
|
||||
- Use your judgment to merge changes sensibly
|
||||
|
||||
**Output On Success**
|
||||
|
||||
```
|
||||
## Specs Synced: <change-name>
|
||||
|
||||
Updated main specs:
|
||||
|
||||
**<capability-1>**:
|
||||
- Added requirement: "New Feature"
|
||||
- Modified requirement: "Existing Feature" (added 1 scenario)
|
||||
|
||||
**<capability-2>**:
|
||||
- Created new spec file
|
||||
- Added requirement: "Another Feature"
|
||||
|
||||
Main specs are now updated. The change remains active - archive when implementation is complete.
|
||||
```
|
||||
|
||||
**Guardrails**
|
||||
|
||||
- Read both delta and main specs before making changes
|
||||
- Preserve existing content not mentioned in delta
|
||||
- If something is unclear, ask for clarification
|
||||
- Show what you're changing as you go
|
||||
- The operation should be idempotent - running twice should give same result

Verify that an implementation matches the change artifacts (specs, tasks, design).
|
||||
|
||||
**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
|
||||
|
||||
**Steps**
|
||||
|
||||
1. **If no change name provided, prompt for selection**
|
||||
|
||||
Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
|
||||
|
||||
Show changes that have implementation tasks (tasks artifact exists).
|
||||
Include the schema used for each change if available.
|
||||
Mark changes with incomplete tasks as "(In Progress)".
|
||||
|
||||
**IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
|
||||
|
||||
2. **Check status to understand the schema**
|
||||
|
||||
```bash
|
||||
openspec status --change "<name>" --json
|
||||
```
|
||||
|
||||
Parse the JSON to understand:
|
||||
- `schemaName`: The workflow being used (e.g., "spec-driven")
|
||||
- Which artifacts exist for this change
|
||||
|
||||
3. **Get the change directory and load artifacts**
|
||||
|
||||
```bash
|
||||
openspec instructions apply --change "<name>" --json
|
||||
```
|
||||
|
||||
This returns the change directory and context files. Read all available artifacts from `contextFiles`.
|
||||
|
||||
4. **Initialize verification report structure**
|
||||
|
||||
Create a report structure with three dimensions:
|
||||
- **Completeness**: Track tasks and spec coverage
|
||||
- **Correctness**: Track requirement implementation and scenario coverage
|
||||
- **Coherence**: Track design adherence and pattern consistency
|
||||
|
||||
Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
|
||||
|
||||
5. **Verify Completeness**
|
||||
|
||||
**Task Completion**:
|
||||
- If tasks.md exists in contextFiles, read it
|
||||
- Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
|
||||
- Count complete vs total tasks
|
||||
- If incomplete tasks exist:
|
||||
- Add CRITICAL issue for each incomplete task
|
||||
- Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
|
||||
|
||||
**Spec Coverage**:
|
||||
- If delta specs exist in `openspec/changes/<name>/specs/`:
|
||||
- Extract all requirements (marked with "### Requirement:")
|
||||
- For each requirement:
|
||||
- Search codebase for keywords related to the requirement
|
||||
- Assess if implementation likely exists
|
||||
- If requirements appear unimplemented:
|
||||
- Add CRITICAL issue: "Requirement not found: <requirement name>"
|
||||
- Recommendation: "Implement requirement X: <description>"
|
||||
|
||||
6. **Verify Correctness**
|
||||
|
||||
**Requirement Implementation Mapping**:
|
||||
- For each requirement from delta specs:
|
||||
- Search codebase for implementation evidence
|
||||
- If found, note file paths and line ranges
|
||||
- Assess if implementation matches requirement intent
|
||||
- If divergence detected:
|
||||
- Add WARNING: "Implementation may diverge from spec: <details>"
|
||||
- Recommendation: "Review <file>:<lines> against requirement X"
|
||||
|
||||
**Scenario Coverage**:
|
||||
- For each scenario in delta specs (marked with "#### Scenario:"):
|
||||
- Check if conditions are handled in code
|
||||
- Check if tests exist covering the scenario
|
||||
- If scenario appears uncovered:
|
||||
- Add WARNING: "Scenario not covered: <scenario name>"
|
||||
- Recommendation: "Add test or implementation for scenario: <description>"
|
||||
|
||||
7. **Verify Coherence**
|
||||
|
||||
**Design Adherence**:
|
||||
- If design.md exists in contextFiles:
|
||||
- Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
|
||||
- Verify implementation follows those decisions
|
||||
- If contradiction detected:
|
||||
- Add WARNING: "Design decision not followed: <decision>"
|
||||
- Recommendation: "Update implementation or revise design.md to match reality"
|
||||
- If no design.md: Skip design adherence check, note "No design.md to verify against"
|
||||
|
||||
**Code Pattern Consistency**:
|
||||
- Review new code for consistency with project patterns
|
||||
- Check file naming, directory structure, coding style
|
||||
- If significant deviations found:
|
||||
- Add SUGGESTION: "Code pattern deviation: <details>"
|
||||
- Recommendation: "Consider following project pattern: <example>"
|
||||
|
||||
8. **Generate Verification Report**
|
||||
|
||||
**Summary Scorecard**:
|
||||
|
||||
```
|
||||
## Verification Report: <change-name>
|
||||
|
||||
### Summary
|
||||
| Dimension | Status |
|
||||
|--------------|------------------|
|
||||
| Completeness | X/Y tasks, N reqs|
|
||||
| Correctness | M/N reqs covered |
|
||||
| Coherence | Followed/Issues |
|
||||
```
|
||||
|
||||
**Issues by Priority**:
|
||||
1. **CRITICAL** (Must fix before archive):
|
||||
- Incomplete tasks
|
||||
- Missing requirement implementations
|
||||
- Each with specific, actionable recommendation
|
||||
|
||||
2. **WARNING** (Should fix):
|
||||
- Spec/design divergences
|
||||
- Missing scenario coverage
|
||||
- Each with specific recommendation
|
||||
|
||||
3. **SUGGESTION** (Nice to fix):
|
||||
- Pattern inconsistencies
|
||||
- Minor improvements
|
||||
- Each with specific recommendation
|
||||
|
||||
**Final Assessment**:
|
||||
- If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
|
||||
- If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
|
||||
- If all clear: "All checks passed. Ready for archive."
|
||||
|
||||
**Verification Heuristics**
|
||||
|
||||
- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
|
||||
- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
|
||||
- **Coherence**: Look for glaring inconsistencies, don't nitpick style
|
||||
- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
|
||||
- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
|
||||
|
||||
**Graceful Degradation**
|
||||
|
||||
- If only tasks.md exists: verify task completion only, skip spec/design checks
|
||||
- If tasks + specs exist: verify completeness and correctness, skip design
|
||||
- If full artifacts: verify all three dimensions
|
||||
- Always note which checks were skipped and why
|
||||
|
||||
**Output Format**
|
||||
|
||||
Use clear markdown with:
|
||||
|
||||
- Table for summary scorecard
|
||||
- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
|
||||
- Code references in format: `file.ts:123`
|
||||
- Specific, actionable recommendations
|
||||
- No vague suggestions like "consider reviewing"

# Gemini Nexus Manager Developer Guide
|
||||
|
||||
## 🏗️ Architecture Overview
|
||||
|
||||
Gemini Nexus Manager is a hybrid Desktop Application built with Electron, React, and NestJS. It follows a modular architecture where the frontend (Renderer) communicates with the backend (Main) via type-safe IPC (ORPC).
|
||||
|
||||
```mermaid
|
||||

|
||||
Services -->|Read/Write| DB[(SQLite Database)]
|
||||
Services -->|HTTP| Cloud[Cloud APIs (Google/Anthropic)]
|
||||
```
|
||||
|
||||
### Key Technologies
|
||||
|
||||
- **Frontend**: React 19, TailwindCSS v4, TanStack Router, TanStack Query.
|
||||
- **Backend**: Electron (Main), NestJS (Core Logic), Better-SQLite3 (Data).
|
||||
- **Communication**: ORPC (Type-safe IPC wrapper around Electron IPC).
|
||||
- **Build**: Electron Forge + Vite.
|
||||
|
||||
## 📂 Directory Structure
|
||||
|
||||
- `src/main.ts`: Electron Main Process entry point.
|
||||
- `src/preload.ts`: Bridge between Main and Renderer.
|
||||
- `src/renderer.tsx`: React App entry point.
|
||||
- `src/components/`: Reusable React UI components (Radix UI based).
|
||||
- `src/ipc/`: IPC Routers and Handlers (Domain logic).
|
||||
- `router.ts`: Main ORPC router definition.
|
||||
- `account/`, `cloud/`, `database/`: Domain-specific handlers.
|
||||
- `src/server/`: NestJS application modules (proxies/gateways).
|
||||
- `src/services/`: Core business logic (framework agnostic).
|
||||
- `GoogleAPIService.ts`: Gemini/Cloud interactions.
|
||||
- `AutoSwitchService.ts`: Account rotation logic.
|
||||
- `src/routes/`: Frontend routing definitions (File-based).
|
||||
|
||||
## 🚀 Development Workflow
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Node.js 18+
|
||||
- npm (Project uses `package-lock.json`)
|
||||
|
||||
### Common Commands
|
||||
|
||||
- **Start Dev Server**: `npm start`
|
||||
- **Lint Code**: `npm run lint`
|
||||
- **Unit Test**: `npm run test:unit`
|
||||
- **E2E Test**: `npm run test:e2e`
|
||||
- **Build Production**: `npm run make`
|
||||
|
||||
## 🧠 Core Concepts
|
||||
|
||||
### IPC Communication (ORPC)
|
||||
|
||||
The project uses `orpc` for type-safe communication.
|
||||
|
||||
- **Define**: Create a router in `src/ipc/router.ts` with Zod schemas.
|
||||
- **Implement**: Add logic in handlers (e.g., `src/ipc/account/handler.ts`).
|
||||
- **Call**: Use the generated client in React components.
|
||||
|
||||
### Database Access
|
||||
|
||||
Data is stored in a local SQLite file.
|
||||
|
||||
- Use `Better-SQLite3` for direct access.
|
||||
- Logic should be encapsulated in `src/services` or `src/ipc`.
|
||||
|
||||
### Account Management
|
||||
|
||||
- Accounts are added via OAuth (Google/Claude).
|
||||
- `GoogleAPIService` handles token exchange and refreshing.
|
||||
- `AutoSwitchService` monitors usage and switches active accounts automatically.
|
||||
|
||||
## ⚠️ Critical Rules
|
||||
|
||||
1. **Type Safety**: strict TypeScript usage; Zod for runtime validation.
|
||||
2. **Components**: Use `src/components/ui` (Radix primitives) for consistency.
|
||||
3. **Async**: Handle all IPC/DB calls asynchronously with try/catch.
|
||||
4. **Security**: Never commit secrets. API keys are user-provided or encrypted locally.

## Prerequisites
|
||||
|
||||
Check if Python is installed:
|
||||
|
||||
```bash
|
||||
python3 --version || python --version
|
||||
```
|
||||
|
||||
If Python is not installed, install it based on user's OS:
|
||||
|
||||
**macOS:**
|
||||
|
||||
```bash
|
||||
brew install python3
|
||||
```
|
||||
|
||||
**Ubuntu/Debian:**
|
||||
|
||||
```bash
|
||||
sudo apt update && sudo apt install python3
|
||||
```
|
||||
|
||||
**Windows:**
|
||||
|
||||
```powershell
|
||||
winget install Python.Python.3.12
|
||||
```
|
||||
|
||||

|
||||
|
||||
## How to Use This Skill
|
||||
|
||||
When user requests UI/UX work (design, build, create, implement, review, fix, improve), follow this workflow:
|
||||
|
||||
### Step 1: Analyze User Requirements
|
||||
|
||||
Extract key information from user request:
|
||||
|
||||
- **Product type**: SaaS, e-commerce, portfolio, dashboard, landing page, etc.
|
||||
- **Style keywords**: minimal, playful, professional, elegant, dark mode, etc.
|
||||
- **Industry**: healthcare, fintech, gaming, education, etc.
|
||||
- **Stack**: React, Vue, Next.js, or default to `html-tailwind`
|
||||
|
||||
### Step 2: Generate Design System (REQUIRED)
|
||||
|
||||
**Always start with `--design-system`** to get comprehensive recommendations with reasoning:
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "<product_type> <industry> <keywords>" --design-system [-p "Project Name"]
|
||||
```
|
||||
|
||||
This command:
|
||||
|
||||
1. Searches 5 domains in parallel (product, style, color, landing, typography)
|
||||
2. Applies reasoning rules from `ui-reasoning.csv` to select best matches
|
||||
3. Returns complete design system: pattern, style, colors, typography, effects
|
||||
4. Includes anti-patterns to avoid
|
||||
|
||||
**Example:**
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service" --design-system -p "Serenity Spa"
|
||||
```
|
||||
|
||||
### Step 2b: Persist Design System (Master + Overrides Pattern)
|
||||
|
||||
To save the design system for hierarchical retrieval across sessions, add `--persist`:
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Project Name"
|
||||
```
|
||||
|
||||
This creates:
|
||||
|
||||
- `design-system/MASTER.md` — Global Source of Truth with all design rules
|
||||
- `design-system/pages/` — Folder for page-specific overrides
|
||||
|
||||
**With page-specific override:**
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Project Name" --page "dashboard"
|
||||
```
|
||||
|
||||
This also creates:
|
||||
|
||||
- `design-system/pages/dashboard.md` — Page-specific deviations from Master
|
||||
|
||||
**How hierarchical retrieval works:**
|
||||
|
||||
1. When building a specific page (e.g., "Checkout"), first check `design-system/pages/checkout.md`
|
||||
2. If the page file exists, its rules **override** the Master file
|
||||
3. If not, use `design-system/MASTER.md` exclusively
|
||||
|
||||
### Step 3: Supplement with Detailed Searches (as needed)
|
||||
|
||||
After getting the design system, use domain searches to get additional details:
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --domain <domain> [-n <max_results>]
|
||||
```
|
||||
|
||||
**When to use detailed searches:**
|
||||
|
||||
| Need | Domain | Example |
|
||||
| --------------------- | ------------ | --------------------------------------- |
|
||||
| More style options | `style` | `--domain style "glassmorphism dark"` |
|
||||
| Chart recommendations | `chart` | `--domain chart "real-time dashboard"` |
|
||||
| UX best practices | `ux` | `--domain ux "animation accessibility"` |
|
||||
| Alternative fonts | `typography` | `--domain typography "elegant luxury"` |
|
||||
| Landing structure | `landing` | `--domain landing "hero social-proof"` |
|
||||
|
||||
### Step 4: Stack Guidelines (Default: html-tailwind)
|
||||
|
||||
Get implementation-specific best practices. If user doesn't specify a stack, **default to `html-tailwind`**.
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --stack html-tailwind
|
||||
```
|
||||
|
||||
Available stacks: `html-tailwind`, `react`, `nextjs`, `vue`, `svelte`, `swiftui`, `react-native`, `flutter`, `shadcn`, `jetpack-compose`

---
|
||||
|
||||
## Example Workflow
|
||||
|
||||
**User request:** "Làm landing page cho dịch vụ chăm sóc da chuyên nghiệp"
|
||||
|
||||
### Step 1: Analyze Requirements
|
||||
|
||||
- Product type: Beauty/Spa service
|
||||
- Style keywords: elegant, professional, soft
|
||||
- Industry: Beauty/Wellness
|
||||
- Stack: html-tailwind (default)
|
||||
|
||||
### Step 2: Generate Design System (REQUIRED)
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service elegant" --design-system -p "Serenity Spa"
|
||||
```
|
||||
|
||||
**Output:** Complete design system with pattern, style, colors, typography, effects, and anti-patterns.
|
||||
|
||||
### Step 3: Supplement with Detailed Searches (as needed)
|
||||
|
||||
```bash
|
||||
# Get UX guidelines for animation and accessibility
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "animation accessibility" --domain ux
|
||||
|
||||
# Get alternative typography options if needed
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "elegant luxury serif" --domain typography
|
||||
```
|
||||
|
||||
### Step 4: Stack Guidelines
|
||||
|
||||
```bash
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "layout responsive form" --stack html-tailwind
|
||||
```
|
||||
|
||||
**Then:** Synthesize design system + detailed searches and implement the design.
|
||||
|
||||
---
|
||||
|
||||
## Output Formats
|
||||
|
||||
The `--design-system` flag supports two output formats:
|
||||
|
||||
```bash
|
||||
# ASCII box (default) - best for terminal display
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system
|
||||
|
||||
# Markdown - best for documentation
|
||||
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system -f markdown
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Tips for Better Results
|
||||
|
||||
1. **Be specific with keywords** - "healthcare SaaS dashboard" > "app"
|
||||
2. **Search multiple times** - Different keywords reveal different insights
|
||||
3. **Combine domains** - Style + Typography + Color = Complete design system
|
||||
4. **Always check UX** - Search "animation", "z-index", "accessibility" for common issues
|
||||
5. **Use stack flag** - Get implementation-specific best practices
|
||||
6. **Iterate** - If first search doesn't match, try different keywords
|
||||

|
||||
|
||||
## Common Rules for Professional UI
|
||||
|
||||
These are frequently overlooked issues that make UI look unprofessional:
|
||||
|
||||
### Icons & Visual Elements
|
||||
|
||||
| Rule | Do | Don't |
|
||||
| -------------------------- | ----------------------------------------------- | -------------------------------------- |
|
||||
| **No emoji icons** | Use SVG icons (Heroicons, Lucide, Simple Icons) | Use emojis like 🎨 🚀 ⚙️ as UI icons |
|
||||
| **Stable hover states** | Use color/opacity transitions on hover | Use scale transforms that shift layout |
|
||||
| **Correct brand logos** | Research official SVG from Simple Icons | Guess or use incorrect logo paths |
|
||||
| **Consistent icon sizing** | Use fixed viewBox (24x24) with w-6 h-6 | Mix different icon sizes randomly |
|
||||
|
||||
### Interaction & Cursor
|
||||
|
||||
| Rule | Do | Don't |
|
||||
| ---------------------- | ----------------------------------------------------- | -------------------------------------------- |
|
||||
| **Cursor pointer** | Add `cursor-pointer` to all clickable/hoverable cards | Leave default cursor on interactive elements |
|
||||
| **Hover feedback** | Provide visual feedback (color, shadow, border) | No indication element is interactive |
|
||||
| **Smooth transitions** | Use `transition-colors duration-200` | Instant state changes or too slow (>500ms) |
|
||||
|
||||
### Light/Dark Mode Contrast
|
||||
|
||||
| Rule | Do | Don't |
|
||||
| ------------------------- | ----------------------------------- | --------------------------------------- |
|
||||
| **Glass card light mode** | Use `bg-white/80` or higher opacity | Use `bg-white/10` (too transparent) |
|
||||
| **Text contrast light** | Use `#0F172A` (slate-900) for text | Use `#94A3B8` (slate-400) for body text |
|
||||
| **Muted text light** | Use `#475569` (slate-600) minimum | Use gray-400 or lighter |
|
||||
| **Border visibility** | Use `border-gray-200` in light mode | Use `border-white/10` (invisible) |
|
||||
|
||||
### Layout & Spacing
|
||||
|
||||
| Rule | Do | Don't |
|
||||
| ------------------------ | ----------------------------------- | -------------------------------------- |
|
||||
| **Floating navbar** | Add `top-4 left-4 right-4` spacing | Stick navbar to `top-0 left-0 right-0` |
|
||||
| **Content padding** | Account for fixed navbar height | Let content hide behind fixed elements |
|
||||
| **Consistent max-width** | Use same `max-w-6xl` or `max-w-7xl` | Mix different container widths |
|
||||
|
||||

|
||||
|
||||
## Pre-Delivery Checklist
|
||||
|
||||

## Abstract
|
||||
|
||||
Composition patterns for building flexible, maintainable React components. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. These patterns make codebases easier for both humans and AI agents to work with as they scale.

## 1. Component Architecture
|
||||
|
||||
**Impact: HIGH**
|
||||
|
||||
Fundamental patterns for structuring components to avoid prop
|
||||
proliferation and enable flexible composition.
|
||||
|
||||
### 1.1 Avoid Boolean Prop Proliferation
|
||||
|
||||
**Impact: CRITICAL (prevents unmaintainable component variants)**
|
||||
|
||||
Don't add boolean props like `isThread`, `isEditing`, `isDMThread` to customize
|
||||
|
||||
component behavior. Each boolean doubles possible states and creates
|
||||
|
||||
unmaintainable conditional logic. Use composition instead.
|
||||
|
||||
**Incorrect: boolean props create exponential complexity**
|
||||
|
||||
```tsx
|
||||
function Composer({
|
||||
onSubmit,
|
||||
isThread,
|
||||
channelId,
|
||||
isDMThread,
|
||||
dmId,
|
||||
isEditing,
|
||||
isForwarding,
|
||||
}: Props) {
|
||||
return (
|
||||
<form>
|
||||
<Header />
|
||||
<Input />
|
||||
{isDMThread ? (
|
||||
<AlsoSendToDMField id={dmId} />
|
||||
) : isThread ? (
|
||||
<AlsoSendToChannelField id={channelId} />
|
||||
) : null}
|
||||
{isEditing ? <EditActions /> : isForwarding ? <ForwardActions /> : <DefaultActions />}
|
||||
<Footer onSubmit={onSubmit} />
|
||||
</form>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct: composition eliminates conditionals**
|
||||
|
||||
```tsx
|
||||
// Channel composer
|
||||
function ChannelComposer() {
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Header />
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Attachments />
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.Submit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||
|
||||
// Thread composer - adds "also send to channel" field
|
||||
function ThreadComposer({ channelId }: { channelId: string }) {
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Header />
|
||||
<Composer.Input />
|
||||
<AlsoSendToChannelField id={channelId} />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.Submit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||
|
||||
// Edit composer - different footer actions
|
||||
function EditComposer() {
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.CancelEdit />
|
||||
<Composer.SaveEdit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
Each variant is explicit about what it renders. We can share internals without
|
||||
|
||||
sharing a single monolithic parent.
|
||||
|
||||
### 1.2 Use Compound Components
|
||||
|
||||
**Impact: HIGH (enables flexible composition without prop drilling)**
|
||||
|
||||
Structure complex components as compound components with a shared context. Each
|
||||
|
||||
subcomponent accesses shared state via context, not props. Consumers compose the
|
||||
|
||||
pieces they need.
|
||||
|
||||
**Incorrect: monolithic component with render props**
|
||||
|
||||
```tsx
|
||||
function Composer({
|
||||
renderHeader,
|
||||
renderFooter,
|
||||
renderActions,
|
||||
showAttachments,
|
||||
showFormatting,
|
||||
showEmojis,
|
||||
}: Props) {
|
||||
return (
|
||||
<form>
|
||||
{renderHeader?.()}
|
||||
<Input />
|
||||
{showAttachments && <Attachments />}
|
||||
{renderFooter ? (
|
||||
renderFooter()
|
||||
) : (
|
||||
<Footer>
|
||||
{showFormatting && <Formatting />}
|
||||
{showEmojis && <Emojis />}
|
||||
{renderActions?.()}
|
||||
</Footer>
|
||||
)}
|
||||
</form>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct: compound components with shared context**
|
||||
|
||||
```tsx
|
||||
const ComposerContext = createContext<ComposerContextValue | null>(null);
|
||||
|
||||
function ComposerProvider({ children, state, actions, meta }: ProviderProps) {
|
||||
return <ComposerContext value={{ state, actions, meta }}>{children}</ComposerContext>;
|
||||
}
|
||||
|
||||
function ComposerFrame({ children }: { children: React.ReactNode }) {
|
||||
return <form>{children}</form>;
|
||||
}
|
||||
|
||||
function ComposerInput() {
|
||||
const {
|
||||
state,
|
||||
actions: { update },
|
||||
meta: { inputRef },
|
||||
} = use(ComposerContext);
|
||||
return (
|
||||
<TextInput
|
||||
ref={inputRef}
|
||||
value={state.input}
|
||||
onChangeText={(text) => update((s) => ({ ...s, input: text }))}
|
||||
/>
|
||||
);
|
||||
}
|
||||
|
||||
function ComposerSubmit() {
|
||||
const {
|
||||
actions: { submit },
|
||||
} = use(ComposerContext);
|
||||
return <Button onPress={submit}>Send</Button>;
|
||||
}
|
||||
|
||||
// Export as compound component
|
||||
const Composer = {
|
||||
Provider: ComposerProvider,
|
||||
Frame: ComposerFrame,
|
||||
Input: ComposerInput,
|
||||
Submit: ComposerSubmit,
|
||||
Header: ComposerHeader,
|
||||
Footer: ComposerFooter,
|
||||
Attachments: ComposerAttachments,
|
||||
Formatting: ComposerFormatting,
|
||||
Emojis: ComposerEmojis,
|
||||
};
|
||||
```
|
||||
|
||||
**Usage:**
|
||||
|
||||
```tsx
|
||||
<Composer.Provider state={state} actions={actions} meta={meta}>
|
||||
<Composer.Frame>
|
||||
<Composer.Header />
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Submit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</Composer.Provider>
|
||||
```
|
||||
|
||||
Consumers explicitly compose exactly what they need. No hidden conditionals. And the state, actions and meta are dependency-injected by a parent provider, allowing multiple usages of the same component structure.
|
||||
|
||||

|
||||
|
||||
## 2. State Management
|
||||
|
||||
**Impact: MEDIUM**
|
||||
|
||||
Patterns for lifting state and managing shared context across
|
||||
composed components.
|
||||
|
||||
### 2.1 Decouple State Management from UI
|
||||
|
||||
**Impact: MEDIUM (enables swapping state implementations without changing UI)**
|
||||
|
||||
The provider component should be the only place that knows how state is managed.
|
||||
|
||||
UI components consume the context interface—they don't know if state comes from
|
||||
|
||||
useState, Zustand, or a server sync.
|
||||
|
||||
**Incorrect: UI coupled to state implementation**
|
||||
|
||||
```tsx
|
||||
function ChannelComposer({ channelId }: { channelId: string }) {
|
||||
// UI component knows about global state implementation
|
||||
const state = useGlobalChannelState(channelId);
|
||||
const { submit, updateInput } = useChannelSync(channelId);
|
||||
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Input value={state.input} onChange={(text) => sync.updateInput(text)} />
|
||||
<Composer.Submit onPress={() => sync.submit()} />
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct: state management isolated in provider**
|
||||
|
||||
```tsx
|
||||
// Provider handles all state management details
|
||||
function ChannelProvider({
|
||||
channelId,
|
||||
children,
|
||||
}: {
|
||||
channelId: string;
|
||||
children: React.ReactNode;
|
||||
}) {
|
||||
const { state, update, submit } = useGlobalChannel(channelId);
|
||||
const inputRef = useRef(null);
|
||||
|
||||
return (
|
||||
<Composer.Provider state={state} actions={{ update, submit }} meta={{ inputRef }}>
|
||||
{children}
|
||||
</Composer.Provider>
|
||||
);
|
||||
}
|
||||
|
||||
// UI component only knows about the context interface
|
||||
function ChannelComposer() {
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Header />
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Submit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||
|
||||
// Usage
|
||||
function Channel({ channelId }: { channelId: string }) {
|
||||
return (
|
||||
<ChannelProvider channelId={channelId}>
|
||||
<ChannelComposer />
|
||||
</ChannelProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Different providers, same UI:**
|
||||
|
||||
```tsx
|
||||
// Local state for ephemeral forms
|
||||
function ForwardMessageProvider({ children }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
const forwardMessage = useForwardMessage();
|
||||
|
||||
return (
|
||||
<Composer.Provider state={state} actions={{ update: setState, submit: forwardMessage }}>
|
||||
{children}
|
||||
</Composer.Provider>
|
||||
);
|
||||
}
|
||||
|
||||
// Global synced state for channels
|
||||
function ChannelProvider({ channelId, children }) {
|
||||
const { state, update, submit } = useGlobalChannel(channelId);
|
||||
|
||||
return (
|
||||
<Composer.Provider state={state} actions={{ update, submit }}>
|
||||
{children}
|
||||
</Composer.Provider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
The same `Composer.Input` component works with both providers because it only
|
||||
|
||||
depends on the context interface, not the implementation.
|
||||
|
||||
### 2.2 Define Generic Context Interfaces for Dependency Injection
|
||||
|
||||
**Impact: HIGH (enables dependency-injectable state across use-cases)**
|
||||
|
||||
Define a **generic interface** for your component context with three parts:
|
||||
|
||||
`state`, `actions`, and `meta`. This interface is a contract that any provider
|
||||
|
||||
can implement—enabling the same UI components to work with completely different
|
||||
|
||||
state implementations.
|
||||
|
||||
**Core principle:** Lift state, compose internals, make state
|
||||
|
||||
dependency-injectable.
|
||||
|
||||
**Incorrect: UI coupled to specific state implementation**
|
||||
|
||||
```tsx
|
||||
function ComposerInput() {
|
||||
// Tightly coupled to a specific hook
|
||||
const { input, setInput } = useChannelComposerState();
|
||||
return <TextInput value={input} onChangeText={setInput} />;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct: generic interface enables dependency injection**
|
||||
|
||||
```tsx
|
||||
// Define a GENERIC interface that any provider can implement
|
||||
interface ComposerState {
|
||||
input: string;
|
||||
attachments: Attachment[];
|
||||
isSubmitting: boolean;
|
||||
}
|
||||
|
||||
interface ComposerActions {
|
||||
update: (updater: (state: ComposerState) => ComposerState) => void;
|
||||
submit: () => void;
|
||||
}
|
||||
|
||||
interface ComposerMeta {
|
||||
inputRef: React.RefObject<TextInput>;
|
||||
}
|
||||
|
||||
interface ComposerContextValue {
|
||||
state: ComposerState;
|
||||
actions: ComposerActions;
|
||||
meta: ComposerMeta;
|
||||
}
|
||||
|
||||
const ComposerContext = createContext<ComposerContextValue | null>(null);
|
||||
```
|
||||
|
||||
**UI components consume the interface, not the implementation:**
|
||||
|
||||
```tsx
|
||||
function ComposerInput() {
|
||||
const {
|
||||
state,
|
||||
actions: { update },
|
||||
meta,
|
||||
} = use(ComposerContext);
|
||||
|
||||
// This component works with ANY provider that implements the interface
|
||||
return (
|
||||
<TextInput
|
||||
ref={meta.inputRef}
|
||||
value={state.input}
|
||||
onChangeText={(text) => update((s) => ({ ...s, input: text }))}
|
||||
/>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Different providers implement the same interface:**
|
||||
|
||||
```tsx
|
||||
// Provider A: Local state for ephemeral forms
|
||||
function ForwardMessageProvider({ children }: { children: React.ReactNode }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
const inputRef = useRef(null);
|
||||
const submit = useForwardMessage();
|
||||
|
||||
return (
|
||||
<ComposerContext
|
||||
value={{
|
||||
state,
|
||||
actions: { update: setState, submit },
|
||||
meta: { inputRef },
|
||||
}}
|
||||
>
|
||||
{children}
|
||||
</ComposerContext>
|
||||
);
|
||||
}
|
||||
|
||||
// Provider B: Global synced state for channels
|
||||
function ChannelProvider({ channelId, children }: Props) {
|
||||
const { state, update, submit } = useGlobalChannel(channelId);
|
||||
const inputRef = useRef(null);
|
||||
|
||||
return (
|
||||
<ComposerContext
|
||||
value={{
|
||||
state,
|
||||
actions: { update, submit },
|
||||
meta: { inputRef },
|
||||
}}
|
||||
>
|
||||
{children}
|
||||
</ComposerContext>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**The same composed UI works with both:**
|
||||
|
||||
```tsx
|
||||
// Works with ForwardMessageProvider (local state)
|
||||
<ForwardMessageProvider>
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Submit />
|
||||
</Composer.Frame>
|
||||
</ForwardMessageProvider>
|
||||
|
||||
// Works with ChannelProvider (global synced state)
|
||||
<ChannelProvider channelId="abc">
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Submit />
|
||||
</Composer.Frame>
|
||||
</ChannelProvider>
|
||||
```
|
||||
|
||||
**Custom UI outside the component can access state and actions:**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageDialog() {
|
||||
return (
|
||||
<ForwardMessageProvider>
|
||||
<Dialog>
|
||||
{/* The composer UI */}
|
||||
<Composer.Frame>
|
||||
<Composer.Input placeholder="Add a message, if you'd like." />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
|
||||
{/* Custom UI OUTSIDE the composer, but INSIDE the provider */}
|
||||
<MessagePreview />
|
||||
|
||||
{/* Actions at the bottom of the dialog */}
|
||||
<DialogActions>
|
||||
<CancelButton />
|
||||
<ForwardButton />
|
||||
</DialogActions>
|
||||
</Dialog>
|
||||
</ForwardMessageProvider>
|
||||
);
|
||||
}
|
||||
|
||||
// This button lives OUTSIDE Composer.Frame but can still submit based on its context!
|
||||
function ForwardButton() {
|
||||
const {
|
||||
actions: { submit },
|
||||
} = use(ComposerContext);
|
||||
return <Button onPress={submit}>Forward</Button>;
|
||||
}
|
||||
|
||||
// This preview lives OUTSIDE Composer.Frame but can read composer's state!
|
||||
function MessagePreview() {
|
||||
const { state } = use(ComposerContext);
|
||||
return <Preview message={state.input} attachments={state.attachments} />;
|
||||
}
|
||||
```
|
||||
|
||||
The provider boundary is what matters—not the visual nesting. Components that
|
||||
|
||||
need shared state don't have to be inside the `Composer.Frame`. They just need
|
||||
|
||||
to be within the provider.
|
||||
|
||||
The `ForwardButton` and `MessagePreview` are not visually inside the composer
|
||||
|
||||
box, but they can still access its state and actions. This is the power of
|
||||
|
||||
lifting state into providers.
|
||||
|
||||
The UI is reusable bits you compose together. The state is dependency-injected
|
||||
|
||||
by the provider. Swap the provider, keep the UI.
|
||||
|
||||
### 2.3 Lift State into Provider Components
|
||||
|
||||
**Impact: HIGH (enables state sharing outside component boundaries)**
|
||||
|
||||
Move state management into dedicated provider components. This allows sibling
|
||||
|
||||
components outside the main UI to access and modify state without prop drilling
|
||||
|
||||
or awkward refs.
|
||||
|
||||
**Incorrect: state trapped inside component**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageComposer() {
|
||||
const [state, setState] = useState(initialState);
|
||||
const forwardMessage = useForwardMessage();
|
||||
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Footer />
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||

// Problem: How does this button access composer state?
|
||||
function ForwardMessageDialog() {
|
||||
return (
|
||||
<Dialog>
|
||||
<ForwardMessageComposer />
|
||||
<MessagePreview /> {/* Needs composer state */}
|
||||
<DialogActions>
|
||||
<CancelButton />
|
||||
<ForwardButton /> {/* Needs to call submit */}
|

</Dialog>

```
|
||||
|
||||
**Incorrect: useEffect to sync state up**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageDialog() {
|
||||
const [input, setInput] = useState('');
|
||||
return (
|
||||
<Dialog>
|
||||
<ForwardMessageComposer onInputChange={setInput} />
|
||||
<MessagePreview input={input} />
|
||||
</Dialog>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardMessageComposer({ onInputChange }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
useEffect(() => {
|
||||
onInputChange(state.input); // Sync on every change 😬
|
||||
}, [state.input]);
|
||||
}
|
||||
```
|
||||
|
||||
**Incorrect: reading state from ref on submit**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageDialog() {
|
||||
const stateRef = useRef(null);
|
||||
return (
|
||||
<Dialog>
|
||||
<ForwardMessageComposer stateRef={stateRef} />
|
||||
<ForwardButton onPress={() => submit(stateRef.current)} />
|
||||
</Dialog>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct: state lifted to provider**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageProvider({ children }: { children: React.ReactNode }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
const forwardMessage = useForwardMessage();
|
||||
const inputRef = useRef(null);
|
||||
|
||||
return (
|
||||
<Composer.Provider
|
||||
state={state}
|
||||
actions={{ update: setState, submit: forwardMessage }}
|
||||
meta={{ inputRef }}
|
||||
>
|
||||
{children}
|
||||
</Composer.Provider>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardMessageDialog() {
|
||||
return (
|
||||
<ForwardMessageProvider>
|
||||
<Dialog>
|
||||
<ForwardMessageComposer />
|
||||
<MessagePreview /> {/* Custom components can access state and actions */}
|
||||
<DialogActions>
|
||||
<CancelButton />
|
||||
<ForwardButton /> {/* Custom components can access state and actions */}
|
||||
</DialogActions>
|
||||
</Dialog>
|
||||
</ForwardMessageProvider>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardButton() {
|
||||
const { actions } = use(Composer.Context);
|
||||
return <Button onPress={actions.submit}>Forward</Button>;
|
||||
}
|
||||
```
|
||||
|
||||
The ForwardButton lives outside the Composer.Frame but still has access to the
|
||||
|
||||
submit action because it's within the provider. Even though it's a one-off
|
||||
|
||||
component, it can still access the composer's state and actions from outside the
|
||||
|
||||
UI itself.
|
||||
|
||||
**Key insight:** Components that need shared state don't have to be visually
|
||||
|
||||
nested inside each other—they just need to be within the same provider.

## 3. Implementation Patterns
|
||||
|
||||
**Impact: MEDIUM**
|
||||
|
||||
Specific techniques for implementing compound components and
|
||||
context providers.
|
||||
|
||||
### 3.1 Create Explicit Component Variants
|
||||
|
||||
**Impact: MEDIUM (self-documenting code, no hidden conditionals)**
|
||||
|
||||
Instead of one component with many boolean props, create explicit variant
|
||||
|
||||
components. Each variant composes the pieces it needs. The code documents
|
||||
|
||||
itself.
|
||||
|
||||
**Incorrect: one component, many modes**
|
||||
|
||||
```tsx
|
||||
// What does this component actually render?
|
||||
<Composer isThread isEditing={false} channelId="abc" showAttachments showFormatting={false} />
|
||||
```
|
||||
|
||||
**Correct: explicit variants**
|
||||
|
||||
```tsx
|
||||
// Immediately clear what this renders
|
||||
<ThreadComposer channelId="abc" />
|
||||
|
||||
// Or
|
||||
<EditMessageComposer messageId="xyz" />
|
||||
|
||||
// Or
|
||||
<ForwardMessageComposer messageId="123" />
|
||||
```
|
||||
|
||||
Each implementation is unique, explicit and self-contained. Yet they can each
|
||||
|
||||
use shared parts.
|
||||
|
||||
**Implementation:**
|
||||
|
||||
```tsx
|
||||
function ThreadComposer({ channelId }: { channelId: string }) {
|
||||
return (
|
||||
<ThreadProvider channelId={channelId}>
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<AlsoSendToChannelField channelId={channelId} />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.Submit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</ThreadProvider>
|
||||
);
|
||||
}
|
||||
|
||||
function EditMessageComposer({ messageId }: { messageId: string }) {
|
||||
return (
|
||||
<EditMessageProvider messageId={messageId}>
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.CancelEdit />
|
||||
<Composer.SaveEdit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</EditMessageProvider>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardMessageComposer({ messageId }: { messageId: string }) {
|
||||
return (
|
||||
<ForwardMessageProvider messageId={messageId}>
|
||||
<Composer.Frame>
|
||||
<Composer.Input placeholder="Add a message, if you'd like." />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.Mentions />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</ForwardMessageProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
Each variant is explicit about:
|
||||
|
||||
- What provider/state it uses
|
||||
|
||||
- What UI elements it includes
|
||||
|
||||
- What actions are available
|
||||
|
||||
No boolean prop combinations to reason about. No impossible states.
|
||||
|
||||
### 3.2 Prefer Composing Children Over Render Props
|
||||
|
||||
**Impact: MEDIUM (cleaner composition, better readability)**
|
||||
|
||||
Use `children` for composition instead of `renderX` props. Children are more
|
||||
|
||||
readable, compose naturally, and don't require understanding callback
|
||||
|
||||
signatures.
|
||||
|
||||
**Incorrect: render props**
|
||||
|
||||
```tsx
|
||||
function Composer({
|
||||
renderHeader,
|
||||
renderFooter,
|
||||
renderActions,
|
||||
}: {
|
||||
renderHeader?: () => React.ReactNode;
|
||||
renderFooter?: () => React.ReactNode;
|
||||
renderActions?: () => React.ReactNode;
|
||||
}) {
|
||||
return (
|
||||
<form>
|
||||
{renderHeader?.()}
|
||||
<Input />
|
||||
{renderFooter ? renderFooter() : <DefaultFooter />}
|
||||
{renderActions?.()}
|
||||
</form>
|
||||
);
|
||||
}
|
||||
|
||||
// Usage is awkward and inflexible
|
||||
return (
|
||||
<Composer
|
||||
renderHeader={() => <CustomHeader />}
|
||||
renderFooter={() => (
|
||||
<>
|
||||
<Formatting />
|
||||
<Emojis />
|
||||
</>
|
||||
)}
|
||||
renderActions={() => <SubmitButton />}
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
**Correct: compound components with children**
|
||||
|
||||
```tsx
|
||||
function ComposerFrame({ children }: { children: React.ReactNode }) {
|
||||
return <form>{children}</form>;
|
||||
}
|
||||
|
||||
function ComposerFooter({ children }: { children: React.ReactNode }) {
|
||||
return <footer className="flex">{children}</footer>;
|
||||
}
|
||||
|
||||
// Usage is flexible
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<CustomHeader />
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<SubmitButton />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
);
|
||||
```
|
||||
|
||||
**When render props are appropriate:**
|
||||
|
||||
```tsx
|
||||
// Render props work well when you need to pass data back
|
||||
<List data={items} renderItem={({ item, index }) => <Item item={item} index={index} />} />
|
||||
```
|
||||
|
||||
Use render props when the parent needs to provide data or state to the child.
|
||||
|
||||
Use children when composing static structure.
|
||||

## 4. React 19 APIs
|
||||
|
||||
**Impact: MEDIUM**
|
||||
|
||||
React 19+ only. Don't use `forwardRef`; use `use()` instead of `useContext()`.
|
||||
|
||||
### 4.1 React 19 API Changes
|
||||
|
||||
**Impact: MEDIUM (cleaner component definitions and context usage)**
|
||||
|
||||
> **⚠️ React 19+ only.** Skip this if you're on React 18 or earlier.
|
||||
|
||||
In React 19, `ref` is now a regular prop (no `forwardRef` wrapper needed), and `use()` replaces `useContext()`.
|
||||
|
||||
**Incorrect: forwardRef in React 19**
|
||||
|
||||
```tsx
|
||||
const ComposerInput = forwardRef<TextInput, Props>((props, ref) => {
|
||||
return <TextInput ref={ref} {...props} />;
|
||||
});
|
||||
```
|
||||
|
||||
**Correct: ref as a regular prop**
|
||||
|
||||
```tsx
|
||||
function ComposerInput({ ref, ...props }: Props & { ref?: React.Ref<TextInput> }) {
|
||||
return <TextInput ref={ref} {...props} />;
|
||||
}
|
||||
```
|
||||
|
||||
**Incorrect: useContext in React 19**
|
||||
|
||||
```tsx
|
||||
const value = useContext(MyContext);
|
||||
```
|
||||
|
||||
**Correct: use instead of useContext**
|
||||
|
||||
```tsx
|
||||
const value = use(MyContext);
|
||||
```
|
||||
|
||||
`use()` can also be called conditionally, unlike `useContext()`.

# React Composition Patterns
|
||||
|
||||
Composition patterns for building flexible, maintainable React components. Avoid
|
||||
boolean prop proliferation by using compound components, lifting state, and
|
||||
composing internals. These patterns make codebases easier for both humans and AI
|
||||
agents to work with as they scale.
|
||||
|
||||
## When to Apply
|
||||
|
||||
Reference these guidelines when:
|
||||
|
||||
- Refactoring components with many boolean props
|
||||
- Building reusable component libraries
|
||||
- Designing flexible component APIs
|
||||
- Reviewing component architecture
|
||||
- Working with compound components or context providers
|
||||
|
||||
## Rule Categories by Priority
|
||||
|
||||
| Priority | Category | Impact | Prefix |
|
||||
| -------- | ----------------------- | ------ | --------------- |
|
||||
| 1 | Component Architecture | HIGH | `architecture-` |
|
||||
| 2 | State Management | MEDIUM | `state-` |
|
||||
| 3 | Implementation Patterns | MEDIUM | `patterns-` |
|
||||
| 4 | React 19 APIs | MEDIUM | `react19-` |
|
||||
|
||||
## Quick Reference
|
||||
|
||||
### 1. Component Architecture (HIGH)
|
||||
|
||||
- `architecture-avoid-boolean-props` - Don't add boolean props to customize
|
||||
behavior; use composition
|
||||
- `architecture-compound-components` - Structure complex components with shared
|
||||
context
|
||||
|
||||
### 2. State Management (MEDIUM)
|
||||
|
||||
- `state-decouple-implementation` - Provider is the only place that knows how
|
||||
state is managed
|
||||
- `state-context-interface` - Define generic interface with state, actions, meta
|
||||
for dependency injection
|
||||
- `state-lift-state` - Move state into provider components for sibling access
|
||||
|
||||
### 3. Implementation Patterns (MEDIUM)
|
||||
|
||||
- `patterns-explicit-variants` - Create explicit variant components instead of
|
||||
boolean modes
|
||||
- `patterns-children-over-render-props` - Use children for composition instead
|
||||
of renderX props
|
||||
|
||||
### 4. React 19 APIs (MEDIUM)
|
||||
|
||||
> **⚠️ React 19+ only.** Skip this section if using React 18 or earlier.
|
||||
|
||||
- `react19-no-forwardref` - Don't use `forwardRef`; use `use()` instead of `useContext()`
|
||||
|
||||
## How to Use
|
||||
|
||||
Read individual rule files for detailed explanations and code examples:
|
||||
|
||||
```
|
||||
rules/architecture-avoid-boolean-props.md
|
||||
rules/state-context-interface.md
|
||||
```
|
||||
|
||||
Each rule file contains:
|
||||
|
||||
- Brief explanation of why it matters
|
||||
- Incorrect code example with explanation
|
||||
- Correct code example with explanation
|
||||
- Additional context and references

|

## Avoid Boolean Prop Proliferation
|
||||
|
||||
Don't add boolean props like `isThread`, `isEditing`, `isDMThread` to customize
|
||||
component behavior. Each boolean doubles possible states and creates
|
||||
unmaintainable conditional logic. Use composition instead.
|
||||
|
||||
**Incorrect (boolean props create exponential complexity):**
|
||||
|
||||
```tsx
|
||||
function Composer({
|
||||
onSubmit,
|
||||
isThread,
|
||||
channelId,
|
||||
isDMThread,
|
||||
dmId,
|
||||
isEditing,
|
||||
isForwarding,
|
||||
}: Props) {
|
||||
return (
|
||||
<form>
|
||||
<Header />
|
||||
<Input />
|
||||
{isDMThread ? (
|
||||
<AlsoSendToDMField id={dmId} />
|
||||
) : isThread ? (
|
||||
<AlsoSendToChannelField id={channelId} />
|
||||
) : null}
|
||||
{isEditing ? <EditActions /> : isForwarding ? <ForwardActions /> : <DefaultActions />}
|
||||
<Footer onSubmit={onSubmit} />
|
||||
</form>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (composition eliminates conditionals):**
|
||||
|
||||
```tsx
|

// Channel composer
|
||||
function ChannelComposer() {
|
||||
return (

## Use Compound Components
|
||||
|
||||
Structure complex components as compound components with a shared context. Each
|

subcomponent accesses shared state via context, not props. Consumers compose the
|
||||
pieces they need.
|
||||
|
||||
**Incorrect (monolithic component with render props):**
|
||||
|
||||
```tsx
|
||||
function Composer({
|
||||
renderHeader,
|
||||
renderFooter,
|
||||
renderActions,
|
||||
showAttachments,
|
||||
showFormatting,
|
||||
showEmojis,
|
||||
}: Props) {
|

return (
|
||||
<form>
|

{renderHeader?.()}

<Input />
|
||||
{showAttachments && <Attachments />}
|
||||
{renderFooter ? (

renderFooter()
|
||||
) : (

||||
<Footer>

{showFormatting && <Formatting />}

||||

|
||||
{renderActions?.()}
|
||||
</Footer>
|
||||
)}
|
||||
</form>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (compound components with shared context):**
|
||||
|
||||
```tsx
|
||||
const ComposerContext = createContext<ComposerContextValue | null>(null);
|
||||
|
||||
function ComposerProvider({ children, state, actions, meta }: ProviderProps) {

<Composer.Input />

<Composer.Footer>

<Composer.Formatting />
|

<Composer.Submit />
|

</Composer.Footer>
|

</Composer.Frame>
|

|
||||
```
|
||||
|
||||
Consumers explicitly compose exactly what they need. No hidden conditionals. And the state, actions and meta are dependency-injected by a parent provider, allowing multiple usages of the same component structure.

|

|

## Prefer Children Over Render Props
|
||||
|
||||
Use `children` for composition instead of `renderX` props. Children are more
|
||||
readable, compose naturally, and don't require understanding callback
|
||||
signatures.
|
||||
|
||||
**Incorrect (render props):**
|
||||
|
||||
```tsx
|
||||
function Composer({
|
||||
renderHeader,
|
||||
renderFooter,
|
||||
renderActions,
|
||||
}: {
|
||||
renderHeader?: () => React.ReactNode;
|
||||
renderFooter?: () => React.ReactNode;
|
||||
renderActions?: () => React.ReactNode;
|
||||
}) {
|
||||
return (
|
||||
<form>
|
||||
{renderHeader?.()}
|
||||
<Input />
|
||||
{renderFooter ? renderFooter() : <DefaultFooter />}
|
||||
{renderActions?.()}
|
||||
</form>
|
||||
);
|
||||
}
|
||||
|
||||
// Usage is awkward and inflexible
|
||||
return (
|
||||
<Composer
|
||||
renderHeader={() => <CustomHeader />}
|
||||
renderFooter={() => (
|
||||
<>
|
||||
<Formatting />
|
||||
<Emojis />
|
||||
</>
|
||||
)}
|
||||
renderActions={() => <SubmitButton />}
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
**Correct (compound components with children):**
|
||||
|
||||
```tsx
|
||||
function ComposerFrame({ children }: { children: React.ReactNode }) {
|
||||
return <form>{children}</form>;
|
||||
}
|
||||
|
||||
function ComposerFooter({ children }: { children: React.ReactNode }) {
|
||||
return <footer className="flex">{children}</footer>;
|
||||
}
|
||||
|
||||
// Usage is flexible
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<CustomHeader />
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<SubmitButton />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
);
|
||||
```
|
||||
|
||||
**When render props are appropriate:**
|
||||
|
||||
```tsx
|
||||
// Render props work well when you need to pass data back
|
||||
<List data={items} renderItem={({ item, index }) => <Item item={item} index={index} />} />
|
||||
```
|
||||
|
||||
Use render props when the parent needs to provide data or state to the child.
|
||||
Use children when composing static structure.

## Create Explicit Component Variants
|
||||
|
||||
Instead of one component with many boolean props, create explicit variant
|
||||
components. Each variant composes the pieces it needs. The code documents
|
||||
itself.
|
||||
|
||||
**Incorrect (one component, many modes):**
|
||||
|
||||
```tsx
|
||||
// What does this component actually render?
|
||||
<Composer isThread isEditing={false} channelId="abc" showAttachments showFormatting={false} />
|
||||
```
|
||||
|
||||
**Correct (explicit variants):**
|
||||
|
||||
```tsx
|
||||
// Immediately clear what this renders
|
||||
<ThreadComposer channelId="abc" />
|
||||
|
||||
// Or
|
||||
<EditMessageComposer messageId="xyz" />
|
||||
|
||||
// Or
|
||||
<ForwardMessageComposer messageId="123" />
|
||||
```
|
||||
|
||||
Each implementation is unique, explicit and self-contained. Yet they can each
|
||||
use shared parts.
|
||||
|
||||
**Implementation:**
|
||||
|
||||
```tsx
|
||||
function ThreadComposer({ channelId }: { channelId: string }) {
|
||||
return (
|
||||
<ThreadProvider channelId={channelId}>
|

<Composer.Frame>

<Composer.Emojis />
|
||||
<Composer.Submit />
|

</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</ThreadProvider>
|
||||
);
|
||||
}
|
||||
|
||||
function EditMessageComposer({ messageId }: { messageId: string }) {
|
||||
return (
|

<EditMessageProvider messageId={messageId}>
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.CancelEdit />
|
||||
<Composer.SaveEdit />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</EditMessageProvider>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardMessageComposer({ messageId }: { messageId: string }) {
|
||||
return (
|
||||
<ForwardMessageProvider messageId={messageId}>

||||

||||
<Composer.Input placeholder="Add a message, if you'd like." />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
<Composer.Mentions />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
</ForwardMessageProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
Each variant is explicit about:
|
||||
|
||||
- What provider/state it uses
|
||||
- What UI elements it includes
|
||||
- What actions are available
|
||||
|
||||
No boolean prop combinations to reason about. No impossible states.

|

|
||||
## Define Generic Context Interfaces for Dependency Injection
|
||||
|
||||
Define a **generic interface** for your component context with three parts:
|
||||
`state`, `actions`, and `meta`. This interface is a contract that any provider
|
||||
can implement—enabling the same UI components to work with completely different
|
||||
state implementations.
|
||||
|
||||
**Core principle:** Lift state, compose internals, make state
|
||||
dependency-injectable.
|
||||
|
||||
**Incorrect (UI coupled to specific state implementation):**
|
||||
|
||||
```tsx
|
||||
function ComposerInput() {
|
||||
// Tightly coupled to a specific hook
|
||||
const { input, setInput } = useChannelComposerState();
|
||||
return <TextInput value={input} onChangeText={setInput} />;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (generic interface enables dependency injection):**
|
||||
|
||||
```tsx
|
||||
// Define a GENERIC interface that any provider can implement
|
||||
interface ComposerState {
|
||||
input: string;
|
||||
attachments: Attachment[];
|
||||
isSubmitting: boolean;
|
||||
}
|
||||
|
||||
interface ComposerActions {
|
||||
update: (updater: (state: ComposerState) => ComposerState) => void;
|
||||
submit: () => void;
|
||||
}
|
||||
|
||||
interface ComposerMeta {
|
||||
inputRef: React.RefObject<TextInput>;
|
||||
}
|
||||
|
||||
interface ComposerContextValue {
|
||||
state: ComposerState;
|
||||
actions: ComposerActions;
|
||||
meta: ComposerMeta;
|
||||
}
|
||||
|
||||
const ComposerContext = createContext<ComposerContextValue | null>(null);
|
||||
```
|
||||
|
||||
**UI components consume the interface, not the implementation:**
|
||||
|
||||
```tsx
|
||||
function ComposerInput() {
|
||||
const {
|
||||
state,
|
||||
actions: { update },
|
||||
meta,
|
||||
} = use(ComposerContext);
|
||||
|
||||
// This component works with ANY provider that implements the interface
|
||||
return (
|
||||
<TextInput
|
||||
ref={meta.inputRef}
|
||||
value={state.input}
|
||||
onChangeText={(text) => update((s) => ({ ...s, input: text }))}
|
||||
/>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Different providers implement the same interface:**
|
||||
|
||||
```tsx
|
||||
// Provider A: Local state for ephemeral forms
|
||||
function ForwardMessageProvider({ children }: { children: React.ReactNode }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
const inputRef = useRef(null);
|
||||
const submit = useForwardMessage();
|
||||
|
||||
return (
|
||||
<ComposerContext
|
||||
value={{
|
||||
state,
|
||||
actions: { update: setState, submit },
|
||||
meta: { inputRef },
|
||||
}}
|
||||
>
|
||||
{children}
|
||||
</ComposerContext>
|
||||
);
|
||||
}
|
||||
|
||||
// Provider B: Global synced state for channels
|
||||
function ChannelProvider({ channelId, children }: Props) {
|
||||
const { state, update, submit } = useGlobalChannel(channelId);
|
||||
const inputRef = useRef(null);
|
||||
|
||||
return (
|
||||
<ComposerContext
|
||||
value={{
|
||||
state,
|
||||
actions: { update, submit },
|
||||
meta: { inputRef },
|
||||
}}
|
||||
>
|
||||
{children}
|
||||
</ComposerContext>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**The same composed UI works with both:**
|
||||
|
||||
```tsx
|
||||
// Works with ForwardMessageProvider (local state)
|
||||
<ForwardMessageProvider>
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Submit />
|
||||
</Composer.Frame>
|
||||
</ForwardMessageProvider>
|
||||
|
||||
// Works with ChannelProvider (global synced state)
|
||||
<ChannelProvider channelId="abc">
|
||||
<Composer.Frame>
|
||||
<Composer.Input />
|
||||
<Composer.Submit />
|
||||
</Composer.Frame>
|
||||
</ChannelProvider>
|
||||
```
|
||||
|
||||
**Custom UI outside the component can access state and actions:**
|
||||
|
||||
The provider boundary is what matters—not the visual nesting. Components that
|
||||
need shared state don't have to be inside the `Composer.Frame`. They just need
|
||||
to be within the provider.
|
||||
|
||||
```tsx
|
||||
function ForwardMessageDialog() {
|
||||
return (
|
||||
<ForwardMessageProvider>
|
||||
<Dialog>
|
||||
{/* The composer UI */}
|
||||
<Composer.Frame>
|
||||
<Composer.Input placeholder="Add a message, if you'd like." />
|
||||
<Composer.Footer>
|
||||
<Composer.Formatting />
|
||||
<Composer.Emojis />
|
||||
</Composer.Footer>
|
||||
</Composer.Frame>
|
||||
|
||||
{/* Custom UI OUTSIDE the composer, but INSIDE the provider */}
|
||||
<MessagePreview />
|
||||
|
||||
{/* Actions at the bottom of the dialog */}
|
||||
<DialogActions>
|
||||
<CancelButton />
|
||||
<ForwardButton />
|
||||
</DialogActions>
|
||||
</Dialog>
|
||||
</ForwardMessageProvider>
|
||||
);
|
||||
}
|
||||
|
||||
// This button lives OUTSIDE Composer.Frame but can still submit based on its context!
|
||||
function ForwardButton() {
|
||||
const {
|
||||
actions: { submit },
|
||||
} = use(ComposerContext);
|
||||
return <Button onPress={submit}>Forward</Button>;
|
||||
}
|
||||
|
||||
// This preview lives OUTSIDE Composer.Frame but can read composer's state!
|
||||
function MessagePreview() {
|
||||
const { state } = use(ComposerContext);
|
||||
return <Preview message={state.input} attachments={state.attachments} />;
|
||||
}
|
||||
```
|
||||
|
||||
The `ForwardButton` and `MessagePreview` are not visually inside the composer
|
||||
box, but they can still access its state and actions. This is the power of
|
||||
lifting state into providers.
|
||||
|
||||
The UI is reusable bits you compose together. The state is dependency-injected
|
||||
by the provider. Swap the provider, keep the UI.

## Decouple State Management from UI
|
||||
|
||||
The provider component should be the only place that knows how state is managed.
|
||||
UI components consume the context interface—they don't know if state comes from
|
||||
useState, Zustand, or a server sync.
|
||||
|
||||
**Incorrect (UI coupled to state implementation):**
|
||||
|
||||
```tsx
|
||||
function ChannelComposer({ channelId }: { channelId: string }) {
|
||||
// UI component knows about global state implementation
|
||||
const state = useGlobalChannelState(channelId);
|
||||
const { submit, updateInput } = useChannelSync(channelId);
|
||||
|
||||
return (
|
||||
<Composer.Frame>
|
||||
<Composer.Input value={state.input} onChange={(text) => sync.updateInput(text)} />
|
||||
<Composer.Submit onPress={() => sync.submit()} />
|
||||
</Composer.Frame>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (state management isolated in provider):**
|
||||
|
||||
```tsx
|
||||
// Provider handles all state management details
|
||||
function ChannelProvider({
|
||||
channelId,
|
||||
children,
|
||||
}: {
|

channelId: string;

<ChannelComposer />
|
||||
</ChannelProvider>

|

}
|

```

```tsx
|
||||
// Local state for ephemeral forms
|
||||
function ForwardMessageProvider({ children }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
const forwardMessage = useForwardMessage();
|
||||
|
||||
return (
|
||||
<Composer.Provider state={state} actions={{ update: setState, submit: forwardMessage }}>

{children}

**Incorrect (useEffect to sync state up):**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageDialog() {
|
||||
const [input, setInput] = useState('');
|
||||
return (
|
||||
<Dialog>
|
||||
<ForwardMessageComposer onInputChange={setInput} />
|
||||
<MessagePreview input={input} />
|
||||
</Dialog>

|
||||

|
||||
|
||||
function ForwardMessageComposer({ onInputChange }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
useEffect(() => {
|
||||
onInputChange(state.input); // Sync on every change 😬
|
||||
}, [state.input]);
|
||||
}
|
||||
```
|
||||
|
||||
**Incorrect (reading state from ref on submit):**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageDialog() {
|
||||
const stateRef = useRef(null);
|
||||
return (
|
||||
<Dialog>
|
||||
<ForwardMessageComposer stateRef={stateRef} />
|
||||
<ForwardButton onPress={() => submit(stateRef.current)} />
|
||||
</Dialog>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (state lifted to provider):**
|
||||
|
||||
```tsx
|
||||
function ForwardMessageProvider({ children }: { children: React.ReactNode }) {
|
||||
const [state, setState] = useState(initialState);
|
||||
const forwardMessage = useForwardMessage();
|
||||
const inputRef = useRef(null);
|
||||
|
||||
return (
|
||||
<Composer.Provider
|
||||
state={state}
|
||||
actions={{ update: setState, submit: forwardMessage }}
|
||||
meta={{ inputRef }}
|
||||
>
|
||||
{children}
|
||||
</Composer.Provider>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardMessageDialog() {
|
||||
return (
|
||||
<ForwardMessageProvider>
|
||||
<Dialog>
|
||||
<ForwardMessageComposer />
|
||||
<MessagePreview /> {/* Custom components can access state and actions */}
|
||||
<DialogActions>
|
||||
<CancelButton />
|
||||
<ForwardButton /> {/* Custom components can access state and actions */}
|
||||
</DialogActions>
|
||||
</Dialog>
|
||||
</ForwardMessageProvider>
|
||||
);
|
||||
}
|
||||
|
||||
function ForwardButton() {
|
||||
const { actions } = use(Composer.Context);
|
||||
return <Button onPress={actions.submit}>Forward</Button>;
|
||||
}
|
||||
```
|
||||
|
||||
The ForwardButton lives outside the Composer.Frame but still has access to the
|
||||
submit action because it's within the provider. Even though it's a one-off
|
||||
component, it can still access the composer's state and actions from outside the
|
||||
UI itself.
|
||||
|
||||
**Key insight:** Components that need shared state don't have to be visually
|
||||
nested inside each other—they just need to be within the same provider.
|
||||
File diff suppressed because it is too large.

# Vercel React Best Practices
|
||||
|
||||
Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 57 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
|
||||
|
||||
## When to Apply
|
||||
|
||||
Reference these guidelines when:
|
||||
|
||||
- Writing new React components or Next.js pages
|
||||
- Implementing data fetching (client or server-side)
|
||||
- Reviewing code for performance issues
|
||||
- Refactoring existing React/Next.js code
|
||||
- Optimizing bundle size or load times
|
||||
|
||||
## Rule Categories by Priority
|
||||
|
||||
| Priority | Category | Impact | Prefix |
|
||||
| -------- | ------------------------- | ----------- | ------------ |
|
||||
| 1 | Eliminating Waterfalls | CRITICAL | `async-` |
|
||||
| 2 | Bundle Size Optimization | CRITICAL | `bundle-` |
|
||||
| 3 | Server-Side Performance | HIGH | `server-` |
|
||||
| 4 | Client-Side Data Fetching | MEDIUM-HIGH | `client-` |
|
||||
| 5 | Re-render Optimization | MEDIUM | `rerender-` |
|
||||
| 6 | Rendering Performance | MEDIUM | `rendering-` |
|
||||
| 7 | JavaScript Performance | LOW-MEDIUM | `js-` |
|
||||
| 8 | Advanced Patterns | LOW | `advanced-` |
|
||||
|
||||
## Quick Reference
|
||||
|
||||
### 1. Eliminating Waterfalls (CRITICAL)
|
||||
|
||||
- `async-defer-await` - Move await into branches where actually used
|
||||
- `async-parallel` - Use Promise.all() for independent operations
|
||||
- `async-dependencies` - Use better-all for partial dependencies
|
||||
- `async-api-routes` - Start promises early, await late in API routes
|
||||
- `async-suspense-boundaries` - Use Suspense to stream content
|
||||
|
||||
### 2. Bundle Size Optimization (CRITICAL)
|
||||
|
||||
- `bundle-barrel-imports` - Import directly, avoid barrel files
|
||||
- `bundle-dynamic-imports` - Use next/dynamic for heavy components
|
||||
- `bundle-defer-third-party` - Load analytics/logging after hydration
|
||||
- `bundle-conditional` - Load modules only when feature is activated
|
||||
- `bundle-preload` - Preload on hover/focus for perceived speed
|
||||
|
||||
### 3. Server-Side Performance (HIGH)
|
||||
|
||||
- `server-auth-actions` - Authenticate server actions like API routes
|
||||
- `server-cache-react` - Use React.cache() for per-request deduplication
|
||||
- `server-cache-lru` - Use LRU cache for cross-request caching
|
||||
- `server-dedup-props` - Avoid duplicate serialization in RSC props
|
||||
- `server-serialization` - Minimize data passed to client components
|
||||
- `server-parallel-fetching` - Restructure components to parallelize fetches
|
||||
- `server-after-nonblocking` - Use after() for non-blocking operations
|
||||
|
||||
### 4. Client-Side Data Fetching (MEDIUM-HIGH)
|
||||
|
||||
- `client-swr-dedup` - Use SWR for automatic request deduplication
|
||||
- `client-event-listeners` - Deduplicate global event listeners
|
||||
- `client-passive-event-listeners` - Use passive listeners for scroll
|
||||
- `client-localstorage-schema` - Version and minimize localStorage data
|
||||
|
||||
### 5. Re-render Optimization (MEDIUM)
|
||||
|
||||
- `rerender-defer-reads` - Don't subscribe to state only used in callbacks
|
||||
- `rerender-memo` - Extract expensive work into memoized components
|
||||
- `rerender-memo-with-default-value` - Hoist default non-primitive props
|
||||
- `rerender-dependencies` - Use primitive dependencies in effects
|
||||
- `rerender-derived-state` - Subscribe to derived booleans, not raw values
|
||||
- `rerender-derived-state-no-effect` - Derive state during render, not effects
|
||||
- `rerender-functional-setstate` - Use functional setState for stable callbacks
|
||||
- `rerender-lazy-state-init` - Pass function to useState for expensive values
|
||||
- `rerender-simple-expression-in-memo` - Avoid memo for simple primitives
|
||||
- `rerender-move-effect-to-event` - Put interaction logic in event handlers
|
||||
- `rerender-transitions` - Use startTransition for non-urgent updates
|
||||
- `rerender-use-ref-transient-values` - Use refs for transient frequent values
|
||||
|
||||
### 6. Rendering Performance (MEDIUM)
|
||||
|
||||
- `rendering-animate-svg-wrapper` - Animate div wrapper, not SVG element
|
||||
- `rendering-content-visibility` - Use content-visibility for long lists
|
||||
- `rendering-hoist-jsx` - Extract static JSX outside components
|
||||
- `rendering-svg-precision` - Reduce SVG coordinate precision
|
||||
- `rendering-hydration-no-flicker` - Use inline script for client-only data
|
||||
- `rendering-hydration-suppress-warning` - Suppress expected mismatches
|
||||
- `rendering-activity` - Use Activity component for show/hide
|
||||
- `rendering-conditional-render` - Use ternary, not && for conditionals
|
||||
- `rendering-usetransition-loading` - Prefer useTransition for loading state
|
||||
|
||||
### 7. JavaScript Performance (LOW-MEDIUM)
|
||||
|
||||
- `js-batch-dom-css` - Group CSS changes via classes or cssText
|
||||
- `js-index-maps` - Build Map for repeated lookups
|
||||
- `js-cache-property-access` - Cache object properties in loops
|
||||
- `js-cache-function-results` - Cache function results in module-level Map
|
||||
- `js-cache-storage` - Cache localStorage/sessionStorage reads
|
||||
- `js-combine-iterations` - Combine multiple filter/map into one loop
|
||||
- `js-length-check-first` - Check array length before expensive comparison
|
||||
- `js-early-exit` - Return early from functions
|
||||
- `js-hoist-regexp` - Hoist RegExp creation outside loops
|
||||
- `js-min-max-loop` - Use loop for min/max instead of sort
|
||||
- `js-set-map-lookups` - Use Set/Map for O(1) lookups
|
||||
- `js-tosorted-immutable` - Use toSorted() for immutability
|
||||
|
||||
### 8. Advanced Patterns (LOW)
|
||||
|
||||
- `advanced-event-handler-refs` - Store event handlers in refs
|
||||
- `advanced-init-once` - Initialize app once per app load
|
||||
- `advanced-use-latest` - useLatest for stable callback refs
|
||||
|
||||
## How to Use
|
||||
|
||||
Read individual rule files for detailed explanations and code examples:
|
||||
|
||||
```
|
||||
rules/async-parallel.md
|
||||
rules/bundle-barrel-imports.md
|
||||
```
|
||||
|
||||
Each rule file contains:

||||
|
||||
- Brief explanation of why it matters
|
||||
- Incorrect code example with explanation
|
||||
- Correct code example with explanation
|
||||

## Store Event Handlers in Refs
|
||||
|
||||
Store callbacks in refs when used in effects that shouldn't re-subscribe on callback changes.
|
||||
|
||||
**Incorrect (re-subscribes on every render):**
|
||||
|
||||
```tsx
|
||||
function useWindowEvent(event: string, handler: (e) => void) {
|
||||
useEffect(() => {
|
||||
window.addEventListener(event, handler);
|
||||
return () => window.removeEventListener(event, handler);
|
||||
}, [event, handler]);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (stable subscription):**
|
||||
|
||||
```tsx
|
||||
function useWindowEvent(event: string, handler: (e) => void) {
|
||||
const handlerRef = useRef(handler);
|
||||
useEffect(() => {
|
||||
handlerRef.current = handler;
|
||||
}, [handler]);
|
||||
|
||||
useEffect(() => {
|
||||
const listener = (e) => handlerRef.current(e);
|
||||
window.addEventListener(event, listener);
|
||||
return () => window.removeEventListener(event, listener);
|
||||
}, [event]);
|
||||
}
|
||||
```
|
||||
|
||||
**Alternative: use `useEffectEvent` if you're on latest React:**
|
||||
|
||||
```tsx
|
||||
import { useEffectEvent } from 'react';
|
||||
|
||||
function useWindowEvent(event: string, handler: (e) => void) {
|
||||
const onEvent = useEffectEvent(handler);
|
||||
|
||||
useEffect(() => {
|
||||
window.addEventListener(event, onEvent);
|
||||
return () => window.removeEventListener(event, onEvent);
|
||||
}, [event]);
|
||||
}
|
||||
```
|
||||
|
||||
`useEffectEvent` provides a cleaner API for the same pattern: it creates a stable function reference that always calls the latest version of the handler.

|

## Initialize App Once, Not Per Mount
|
||||
|
||||
Do not put app-wide initialization that must run once per app load inside `useEffect([])` of a component. Components can remount and effects will re-run. Use a module-level guard or top-level init in the entry module instead.
|
||||
|
||||
**Incorrect (runs twice in dev, re-runs on remount):**
|
||||
|
||||
```tsx
|
||||
function Comp() {
|
||||
useEffect(() => {
|
||||
loadFromStorage();
|
||||
checkAuthToken();
|
||||
}, []);
|
||||
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (once per app load):**
|
||||
|
||||
```tsx
|
||||
let didInit = false;
|
||||
|
||||
function Comp() {
|

useEffect(() => {

## Prevent Waterfall Chains in API Routes
|
||||
|
||||
In API routes and Server Actions, start independent operations immediately, even if you don't await them yet.
|
||||
|
||||
**Incorrect (config waits for auth, data waits for both):**
|
||||
|
||||
```typescript
|
||||
export async function GET(request: Request) {
|
||||
const session = await auth();
|
||||
const config = await fetchConfig();
|
||||
const data = await fetchData(session.user.id);
|
||||
return Response.json({ data, config });
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (auth and config start immediately):**
|
||||
|
||||
```typescript
|
||||
export async function GET(request: Request) {
|
||||
const sessionPromise = auth();
|
||||
const configPromise = fetchConfig();
|
||||
const session = await sessionPromise;
|
||||
const [config, data] = await Promise.all([configPromise, fetchData(session.user.id)]);
|
||||
return Response.json({ data, config });
|
||||
}
|
||||
```
|
||||

||||
For operations with more complex dependency chains, use `better-all` to automatically maximize parallelism (see Dependency-Based Parallelization).

tags: async, await, conditional, optimization

|
||||
|
||||
## Defer Await Until Needed
|
||||
|
||||
Move `await` operations into the branches where they're actually used to avoid blocking code paths that don't need them.
|
||||
|
||||
**Incorrect (blocks both branches):**
|
||||
|
||||
```typescript
|
||||
async function handleRequest(userId: string, skipProcessing: boolean) {
|
||||
const userData = await fetchUserData(userId);
|
||||
|
||||
if (skipProcessing) {
|
||||
// Returns immediately but still waited for userData
|
||||
return { skipped: true };
|
||||
}
|
||||
|
||||
// Only this branch uses userData
|
||||
return processUserData(userData);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (only blocks when needed):**
|
||||
|
||||
```typescript
|
||||
async function handleRequest(userId: string, skipProcessing: boolean) {
|
||||
if (skipProcessing) {
|
||||
// Returns immediately without waiting
|
||||
return { skipped: true };
|
||||
}
|
||||
|
||||
// Fetch only when needed
|
||||
const userData = await fetchUserData(userId);
|
||||
return processUserData(userData);
|
||||
}
|
||||
```
|
||||
|
||||
**Another example (early return optimization):**
|
||||
|
||||
```typescript
|
||||
// Incorrect: always fetches permissions
|
||||
async function updateResource(resourceId: string, userId: string) {
|
||||
const permissions = await fetchPermissions(userId);
|
||||
const resource = await getResource(resourceId);
|
||||
|
||||
if (!resource) {
|
||||
return { error: 'Not found' };
|
||||
}
|
||||
|
||||
if (!permissions.canEdit) {
|
||||
return { error: 'Forbidden' };
|
||||
}
|
||||
|
||||
return await updateResourceData(resource, permissions);
|
||||
}
|
||||
|
||||
// Correct: fetches only when needed
|
||||
async function updateResource(resourceId: string, userId: string) {
|
||||
const resource = await getResource(resourceId);
|
||||
|
||||
if (!resource) {
|
||||
return { error: 'Not found' };
|
||||
}
|
||||
|
||||
const permissions = await fetchPermissions(userId);
|
||||
|
||||
if (!permissions.canEdit) {
|
||||
return { error: 'Forbidden' };
|
||||
}
|
||||
|
||||
return await updateResourceData(resource, permissions);
|
||||
}
|
||||
```
|
||||
|
||||
This optimization is especially valuable when the skipped branch is frequently taken, or when the deferred operation is expensive.

## Dependency-Based Parallelization
|
||||
|
||||
For operations with partial dependencies, use `better-all` to maximize parallelism. It automatically starts each task at the earliest possible moment.
|
||||
|
||||
**Incorrect (profile waits for config unnecessarily):**
|
||||
|
||||
```typescript
|
||||
const [user, config] = await Promise.all([fetchUser(), fetchConfig()]);
|
||||
const profile = await fetchProfile(user.id);
|
||||
```
|
||||
|
||||
**Correct (config and profile run in parallel):**
|
||||
|
||||
```typescript
|
||||
import { all } from 'better-all';
|
||||
|
||||
const { user, config, profile } = await all({
|
||||
async user() {
|
||||
return fetchUser();
|
||||
},
|
||||
async config() {
|
||||
return fetchConfig();
|
||||
},
|
||||
async profile() {
|
||||
return fetchProfile((await this.$.user).id);
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||

We can also create all the promises first, and do `Promise.all()` at the end.
|
||||
|
||||
```typescript
|
||||
const userPromise = fetchUser();
|
||||
const profilePromise = userPromise.then((user) => fetchProfile(user.id));
|
||||
|
||||
const [user, config, profile] = await Promise.all([userPromise, fetchConfig(), profilePromise]);
|

|

---
|

|

## Strategic Suspense Boundaries
|
||||
|
||||
Instead of awaiting data in async components before returning JSX, use Suspense boundaries to show the wrapper UI faster while data loads.
|
||||
|
||||
**Incorrect (wrapper blocked by data fetching):**
|
||||
|
||||
```tsx
|
||||
async function Page() {
|
||||
const data = await fetchData(); // Blocks entire page
|
||||
|
||||
return (
|
||||
<div>
|
||||
<div>Sidebar</div>
|
||||
<div>Header</div>
|
||||
<div>
|
||||
<DataDisplay data={data} />
|
||||
</div>
|
||||
<div>Footer</div>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
The entire layout waits for data even though only the middle section needs it.
|
||||
|
||||
**Correct (wrapper shows immediately, data streams in):**
|
||||
|
||||
```tsx
|
||||
function Page() {
|
||||
return (
|
||||
<div>
|
||||
<div>Sidebar</div>
|
||||
<div>Header</div>
|
||||
<div>
|
||||
<Suspense fallback={<Skeleton />}>
|
||||
<DataDisplay />
|
||||
</Suspense>
|
||||
</div>
|
||||
<div>Footer</div>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
async function DataDisplay() {
|
||||
const data = await fetchData(); // Only blocks this component
|
||||
return <div>{data.content}</div>;
|
||||
}
|
||||
```
|
||||
|
||||
Sidebar, Header, and Footer render immediately. Only DataDisplay waits for data.
|
||||
|
||||
**Alternative (share promise across components):**
|
||||
|
||||
```tsx
|
||||
function Page() {
|
||||
// Start fetch immediately, but don't await
|
||||
const dataPromise = fetchData();
|
||||
|
||||
return (
|
||||
<div>
|
||||
<div>Sidebar</div>
|
||||
<div>Header</div>
|
||||
<Suspense fallback={<Skeleton />}>
|
||||
<DataDisplay dataPromise={dataPromise} />
|
||||
<DataSummary dataPromise={dataPromise} />
|
||||
</Suspense>
|
||||
<div>Footer</div>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
function DataDisplay({ dataPromise }: { dataPromise: Promise<Data> }) {
|
||||
const data = use(dataPromise); // Unwraps the promise
|
||||
return <div>{data.content}</div>;
|
||||
}
|
||||
|
||||
function DataSummary({ dataPromise }: { dataPromise: Promise<Data> }) {
|
||||
const data = use(dataPromise); // Reuses the same promise
|
||||
return <div>{data.summary}</div>;
|
||||
}
|
||||
```
|
||||
|
||||
Both components share the same promise, so only one fetch occurs. Layout renders immediately while both components wait together.
|
||||
|
||||
**When NOT to use this pattern:**
|
||||
|
||||
- Critical data needed for layout decisions (affects positioning)
|
||||
- SEO-critical content above the fold
|
||||
- Small, fast queries where suspense overhead isn't worth it
|
||||
- When you want to avoid layout shift (loading → content jump)
|
||||
|
||||
**Trade-off:** Faster initial paint vs potential layout shift. Choose based on your UX priorities.

title: Avoid Barrel File Imports
|
||||
impact: CRITICAL
|
||||
impactDescription: 200-800ms import cost, slow builds
|
||||
tags: bundle, imports, tree-shaking, barrel-files, performance
|
||||
---
|
||||
|
||||
## Avoid Barrel File Imports
|
||||
|
||||
Import directly from source files instead of barrel files to avoid loading thousands of unused modules. **Barrel files** are entry points that re-export multiple modules (e.g., `index.js` that does `export * from './module'`).
|
||||
|
||||
Popular icon and component libraries can have **up to 10,000 re-exports** in their entry file. For many React packages, **it takes 200-800ms just to import them**, affecting both development speed and production cold starts.
|
||||
|
||||
**Why tree-shaking doesn't help:** When a library is marked as external (not bundled), the bundler can't optimize it. If you bundle it to enable tree-shaking, builds become substantially slower analyzing the entire module graph.
|
||||
|
||||
**Incorrect (imports entire library):**
|
||||
|
||||
```tsx
|
||||
import { Check, X, Menu } from 'lucide-react';
|
||||
// Loads 1,583 modules, takes ~2.8s extra in dev
|
||||
// Runtime cost: 200-800ms on every cold start
|
||||
|
||||
import { Button, TextField } from '@mui/material';
|
||||
// Loads 2,225 modules, takes ~4.2s extra in dev
|
||||
```
|
||||
|
||||
**Correct (imports only what you need):**
|
||||
|
||||
```tsx
|
||||
import Check from 'lucide-react/dist/esm/icons/check';
|
||||
import X from 'lucide-react/dist/esm/icons/x';
|
||||
import Menu from 'lucide-react/dist/esm/icons/menu';
|
||||
// Loads only 3 modules (~2KB vs ~1MB)
|
||||
|
||||
import Button from '@mui/material/Button';
|
||||
import TextField from '@mui/material/TextField';
|
||||
// Loads only what you use
|
||||
```
|
||||
|
||||
**Alternative (Next.js 13.5+):**
|
||||
|
||||
```js
|
||||
// next.config.js - use optimizePackageImports
|
||||
module.exports = {
|
||||
experimental: {
|
||||
optimizePackageImports: ['lucide-react', '@mui/material'],
|
||||
},
|
||||
};
|
||||
|
||||
// Then you can keep the ergonomic barrel imports:
|
||||
import { Check, X, Menu } from 'lucide-react';
|
||||
// Automatically transformed to direct imports at build time
|
||||
```
|
||||
|
||||
Direct imports provide 15-70% faster dev boot, 28% faster builds, 40% faster cold starts, and significantly faster HMR.
|
||||

||||

## Deduplicate Global Event Listeners
|
||||
|
||||
Use `useSWRSubscription()` to share global event listeners across component instances.
|
||||
|
||||
**Incorrect (N instances = N listeners):**
|
||||
|
||||
```tsx
|
||||
function useKeyboardShortcut(key: string, callback: () => void) {

window.addEventListener('keydown', handler);

return () => window.removeEventListener('keydown', handler);
|

}, [key, callback]);
|
||||
}
|
||||
```
|
||||
|
||||
When using the `useKeyboardShortcut` hook multiple times, each instance will register a new listener.
|
||||
|
||||
**Correct (N instances = 1 listener):**
|
||||
|
||||
```tsx
|
||||
import useSWRSubscription from 'swr/subscription';
|
||||
|
||||
// Module-level Map to track callbacks per key

## Version and Minimize localStorage Data
|
||||
|
||||
Add version prefix to keys and store only needed fields. Prevents schema conflicts and accidental storage of sensitive data.
|
||||
|
||||
**Incorrect:**
|
||||
|
||||
```typescript
|
||||
// No version, stores everything, no error handling
|
||||
localStorage.setItem('userConfig', JSON.stringify(fullUserObject));
|
||||
const data = localStorage.getItem('userConfig');
|
||||
```
|
||||
|
||||
**Correct:**
|
||||
|
||||
```typescript
|
||||
const VERSION = 'v2';
|
||||
|
||||
function saveConfig(config: { theme: string; language: string }) {
|
||||
try {
|
||||
localStorage.setItem(`userConfig:${VERSION}`, JSON.stringify(config));
|
||||
} catch {
|
||||
// Throws in incognito/private browsing, quota exceeded, or disabled
|
||||
}
|
||||
}
|
||||
|
||||
function loadConfig() {
|
||||
try {
|
||||
const data = localStorage.getItem(`userConfig:${VERSION}`);
|
||||
return data ? JSON.parse(data) : null;
|
||||
} catch {
|
||||
return null;
|
||||
}
|
||||
}
|
||||
|
||||
// Migration from v1 to v2
|
||||
function migrate() {
|
||||
try {
|
||||
const v1 = localStorage.getItem('userConfig:v1');
|
||||
if (v1) {
|
||||
const old = JSON.parse(v1);
|
||||
saveConfig({ theme: old.darkMode ? 'dark' : 'light', language: old.lang });
|
||||
localStorage.removeItem('userConfig:v1');
|
||||
}
|
||||
} catch {}
|
||||
}
|
||||
```
|
||||
|
||||
**Store minimal fields from server responses:**
|
||||
|
||||
```typescript
|
||||
// User object has 20+ fields, only store what UI needs
|
||||
function cachePrefs(user: FullUser) {
|
||||
try {
|
||||
localStorage.setItem(
|
||||
'prefs:v1',
|
||||
JSON.stringify({
|
||||
theme: user.preferences.theme,
|
||||
notifications: user.preferences.notifications,
|
||||
}),
|
||||
);
|
||||
} catch {}
|
||||
}
|
||||
```
|
||||
|
||||
**Always wrap in try-catch:** `getItem()` and `setItem()` throw in incognito/private browsing (Safari, Firefox), when quota exceeded, or when disabled.
|
||||
|
||||
**Benefits:** Schema evolution via versioning, reduced storage size, prevents storing tokens/PII/internal flags.

|

## Use SWR for Automatic Deduplication
|
||||
|
||||
SWR enables request deduplication, caching, and revalidation across component instances.
|
||||
|
||||
**Incorrect (no deduplication, each instance fetches):**
|
||||
|
||||
```tsx
|
||||
function UserList() {
|
||||
const [users, setUsers] = useState([]);
|
||||
useEffect(() => {
|
||||
fetch('/api/users')
|
||||
.then((r) => r.json())
|
||||
.then(setUsers);
|
||||
}, []);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (multiple instances share one request):**
|
||||
|
||||
```tsx
|
||||
import useSWR from 'swr';
|
||||
|
||||
function UserList() {
|
||||
const { data: users } = useSWR('/api/users', fetcher);
|
||||
}
|
||||
```
|
||||
|
||||
**For immutable data:**
|
||||
|
||||
```tsx
|
||||
import { useImmutableSWR } from '@/lib/swr';
|
||||
|
||||
function StaticContent() {
|
||||
const { data } = useImmutableSWR('/api/config', fetcher);
|
||||
}
|
||||
```
|
||||
|
||||
**For mutations:**
|
||||
|
||||
```tsx
|
||||
import { useSWRMutation } from 'swr/mutation';
|
||||
|
||||
function UpdateButton() {
|
||||
const { trigger } = useSWRMutation('/api/user', updateUser);
|

return <button onClick={() => trigger()}>Update</button>;
|

}

title: Avoid Layout Thrashing
|
||||
impact: MEDIUM
|
||||
impactDescription: prevents forced synchronous layouts and reduces performance bottlenecks
|
||||
tags: javascript, dom, css, performance, reflow, layout-thrashing
|

---
|
||||
|
||||
## Avoid Layout Thrashing
|
||||
|
||||
Avoid interleaving style writes with layout reads. When you read a layout property (like `offsetWidth`, `getBoundingClientRect()`, or `getComputedStyle()`) between style changes, the browser is forced to trigger a synchronous reflow.
|
||||
|
||||
**This is OK (browser batches style changes):**
|
||||
|
||||
```typescript
|
||||
function updateElementStyles(element: HTMLElement) {
|
||||
// Each line invalidates style, but browser batches the recalculation
|
||||
element.style.width = '100px';
|
||||
element.style.height = '200px';
|
||||
element.style.backgroundColor = 'blue';
|
||||
element.style.border = '1px solid black';
|
||||
}
|
||||
```
|
||||
|
||||
**Incorrect (interleaved reads and writes force reflows):**
|
||||
|
||||
```typescript
|
||||
function layoutThrashing(element: HTMLElement) {
|
||||
element.style.width = '100px';
|
||||
const width = element.offsetWidth; // Forces reflow
|
||||
element.style.height = '200px';
|
||||
const height = element.offsetHeight; // Forces another reflow
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (batch writes, then read once):**
|
||||
|
||||
```typescript
|
||||
function updateElementStyles(element: HTMLElement) {
|
||||
// Batch all writes together
|
||||
element.style.width = '100px';
|
||||
element.style.height = '200px';
|
||||
element.style.backgroundColor = 'blue';
|
||||
element.style.border = '1px solid black';
|
||||
|
||||
// Read after all writes are done (single reflow)
|
||||
const { width, height } = element.getBoundingClientRect();
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (batch reads, then writes):**
|
||||
|
||||
```typescript
|
||||
function avoidThrashing(element: HTMLElement) {
|
||||
// Read phase - all layout queries first
|
||||
const rect1 = element.getBoundingClientRect();
|
||||
const offsetWidth = element.offsetWidth;
|
||||
const offsetHeight = element.offsetHeight;
|
||||
|
||||
// Write phase - all style changes after
|
||||
element.style.width = '100px';
|
||||
element.style.height = '200px';
|
||||
}
|
||||
```
|
||||
|
||||
**Better: use CSS classes**
|
||||
|
||||
```css
|
||||
.highlighted-box {
|
||||
width: 100px;
|
||||
height: 200px;
|
||||
background-color: blue;
|
||||
border: 1px solid black;
|
||||
}
|
||||
```
|
||||
|
||||
```typescript
|
||||
function updateElementStyles(element: HTMLElement) {
|
||||
element.classList.add('highlighted-box');
|
||||
|
||||
const { width, height } = element.getBoundingClientRect();
|
||||
}
|
||||
```
|
||||
|
||||
**React example:**
|
||||
|
||||
```tsx
|
||||
// Incorrect: interleaving style changes with layout queries
|
||||
function Box({ isHighlighted }: { isHighlighted: boolean }) {
|
||||
const ref = useRef<HTMLDivElement>(null);
|
||||
|
||||
useEffect(() => {
|
||||
if (ref.current && isHighlighted) {
|
||||
ref.current.style.width = '100px';
|
||||
const width = ref.current.offsetWidth; // Forces layout
|
||||
ref.current.style.height = '200px';
|
||||
}
|
||||
}, [isHighlighted]);
|
||||
|
||||
return <div ref={ref}>Content</div>;
|
||||
}
|
||||
|
||||
// Correct: toggle class
|
||||
function Box({ isHighlighted }: { isHighlighted: boolean }) {
|
||||
return <div className={isHighlighted ? 'highlighted-box' : ''}>Content</div>;
|
||||
}
|
||||
```
|
||||
|
||||
Prefer CSS classes over inline styles when possible. CSS files are cached by the browser, and classes provide better separation of concerns and are easier to maintain.

title: Cache Repeated Function Calls

tags: javascript, cache, memoization, performance
|

---
|
||||
|
||||
## Cache Repeated Function Calls
|
||||
|
||||
Use a module-level Map to cache function results when the same function is called repeatedly with the same inputs during render.
|
||||
|
||||
**Incorrect (redundant computation):**
|
||||
|
||||
```typescript
|
||||
function ProjectList({ projects }: { projects: Project[] }) {
|
||||
return (
|
||||
<div>
|
||||
{projects.map(project => {
|
||||
// slugify() called 100+ times for same project names
|
||||
const slug = slugify(project.name)
|
||||
|
||||
return <ProjectCard key={project.id} slug={slug} />
|
||||
})}
|
||||
</div>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (cached results):**
|
||||
|
||||
```typescript
|
||||
// Module-level cache
|
||||
const slugifyCache = new Map<string, string>()
|
||||
|
||||
function cachedSlugify(text: string): string {
|
||||
if (slugifyCache.has(text)) {
|
||||
return slugifyCache.get(text)!
|
||||
}
|
||||
const result = slugify(text)
|
||||
slugifyCache.set(text, result)
|
||||
return result
|
||||
}
|
||||
|
||||
function ProjectList({ projects }: { projects: Project[] }) {
|
||||
return (
|
||||
<div>
|
||||
{projects.map(project => {
|
||||
// Computed only once per unique project name
|
||||
const slug = cachedSlugify(project.name)
|
||||
|
||||
return <ProjectCard key={project.id} slug={slug} />
|
||||
})}
|
||||
</div>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
**Simpler pattern for single-value functions:**
|
||||
|
||||
```typescript
|
||||
let isLoggedInCache: boolean | null = null;
|
||||
|
||||
function isLoggedIn(): boolean {
|
||||
if (isLoggedInCache !== null) {
|
||||
return isLoggedInCache;
|
||||
}
|
||||
|
||||
isLoggedInCache = document.cookie.includes('auth=');
|
||||
return isLoggedInCache;
|
||||
}
|
||||
|
||||
// Clear cache when auth changes
|
||||
function onAuthChange() {
|
||||
isLoggedInCache = null;
|
||||
}
|
||||
```
|
||||
|
||||
Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.

tags: javascript, localStorage, storage, caching, performance
|

---
|

|

## Cache Storage API Calls
|
||||
|
||||
`localStorage`, `sessionStorage`, and `document.cookie` are synchronous and expensive. Cache reads in memory.
|
||||
|
||||
**Incorrect (reads storage on every call):**
|
||||
|
||||
```typescript
|
||||
function getTheme() {
|
||||
return localStorage.getItem('theme') ?? 'light';
|
||||
}
|
||||
// Called 10 times = 10 storage reads
|
||||
```
|
||||
|
||||
**Correct (Map cache):**
|
||||
|
||||
```typescript
|
||||
const storageCache = new Map<string, string | null>();
|
||||
|
||||
function getLocalStorage(key: string) {
|
||||
if (!storageCache.has(key)) {
|
||||
storageCache.set(key, localStorage.getItem(key));
|
||||
}
|
||||
return storageCache.get(key);
|
||||
}
|
||||
|
||||
function setLocalStorage(key: string, value: string) {
|
||||
localStorage.setItem(key, value);
|
||||
storageCache.set(key, value); // keep cache in sync
|
||||
}
|
||||
```
|
||||
|
||||
Use a Map (not a hook) so it works everywhere: utilities, event handlers, not just React components.
|
||||
|
||||
**Cookie caching:**
|
||||
|
||||
```typescript
|
||||
let cookieCache: Record<string, string> | null = null;
|
||||
|
||||
function getCookie(name: string) {
|
||||
if (!cookieCache) {
|
||||
cookieCache = Object.fromEntries(document.cookie.split('; ').map((c) => c.split('=')));
|
||||
}
|
||||
return cookieCache[name];
|
||||
}
|
||||
```
|
||||
|
||||
**Important (invalidate on external changes):**
|
||||
|
||||
If storage can change externally (another tab, server-set cookies), invalidate cache:
|
||||
|
||||
```typescript
|
||||
window.addEventListener('storage', (e) => {
|
||||

title: Early Length Check for Array Comparisons

impact: MEDIUM-HIGH
|

impactDescription: avoids expensive operations when lengths differ
|

tags: javascript, arrays, performance, optimization, comparison
|
||||
---
|
||||
|
||||
## Early Length Check for Array Comparisons
|
||||
|
||||
When comparing arrays with expensive operations (sorting, deep equality, serialization), check lengths first. If lengths differ, the arrays cannot be equal.
|
||||
|
||||
In real-world applications, this optimization is especially valuable when the comparison runs in hot paths (event handlers, render loops).
|
||||
|
||||
**Incorrect (always runs expensive comparison):**
|
||||
|
||||
```typescript
|
||||
function hasChanges(current: string[], original: string[]) {
|
||||
// Always sorts and joins, even when lengths differ
|
||||
return current.sort().join() !== original.sort().join();
|
||||
}
|
||||
```
|
||||
|
||||
Two O(n log n) sorts run even when `current.length` is 5 and `original.length` is 100. There is also overhead of joining the arrays and comparing the strings.
|
||||
|
||||
**Correct (O(1) length check first):**
|
||||
|
||||
```typescript
|
||||
function hasChanges(current: string[], original: string[]) {
|
||||
// Early return if lengths differ

if (current.length !== original.length) {

- It avoids the overhead of sorting and joining the arrays when lengths differ
|

- It avoids consuming memory for the joined strings (especially important for large arrays)
|
||||
- It avoids mutating the original arrays
|
||||
- It returns early when a difference is found

## Use Loop for Min/Max Instead of Sort
|
||||
|
||||
Finding the smallest or largest element only requires a single pass through the array. Sorting is wasteful and slower.
|
||||
|
||||
**Incorrect (O(n log n) - sort to find latest):**
|
||||
|
||||
```typescript
|
||||
interface Project {
|
||||
id: string;
|
||||
name: string;
|
||||
updatedAt: number;
|
||||
}
|
||||
|
||||
function getLatestProject(projects: Project[]) {
|
||||
const sorted = [...projects].sort((a, b) => b.updatedAt - a.updatedAt);
|
||||
return sorted[0];
|
||||
}
|
||||
```
|
||||
|
||||
Sorts the entire array just to find the maximum value.
|
||||
|
||||
**Incorrect (O(n log n) - sort for oldest and newest):**
|
||||
|
||||
```typescript
|
||||
function getOldestAndNewest(projects: Project[]) {
|
||||
const sorted = [...projects].sort((a, b) => a.updatedAt - b.updatedAt);
|
||||
return { oldest: sorted[0], newest: sorted[sorted.length - 1] };
|
||||
}
|
||||
```
|
||||
|
||||
Still sorts unnecessarily when only min/max are needed.
|
||||
|
||||
**Correct (O(n) - single loop):**
|
||||
|
||||
```typescript
|
||||
function getLatestProject(projects: Project[]) {
|
||||
if (projects.length === 0) return null;
|
||||
|
||||
let latest = projects[0];
|
||||
|
||||
for (let i = 1; i < projects.length; i++) {
|
||||
if (projects[i].updatedAt > latest.updatedAt) {
|
||||
latest = projects[i];
|
||||
}
|
||||
}
|
||||
|
||||
return latest;
|
||||
}
|
||||
|
||||
function getOldestAndNewest(projects: Project[]) {
|
||||
if (projects.length === 0) return { oldest: null, newest: null };
|
||||
|
||||
let oldest = projects[0];
|
||||
let newest = projects[0];
|
||||
|
||||
for (let i = 1; i < projects.length; i++) {
|
||||
if (projects[i].updatedAt < oldest.updatedAt) oldest = projects[i];
|
||||
if (projects[i].updatedAt > newest.updatedAt) newest = projects[i];
|
||||
}
|
||||
|
||||
return { oldest, newest };
|
||||
}
|
||||
```
|
||||
|
||||
Single pass through the array, no copying, no sorting.
|
||||
|
||||
**Alternative (Math.min/Math.max for small arrays):**
|
||||
|
||||
```typescript
|
||||
const numbers = [5, 2, 8, 1, 9];
|
||||
const min = Math.min(...numbers);
|
||||
const max = Math.max(...numbers);
|
||||
```
|
||||
|
||||
This works for small arrays, but can be slower or just throw an error for very large arrays due to spread operator limitations. Maximal array length is approximately 124000 in Chrome 143 and 638000 in Safari 18; exact numbers may vary - see [the fiddle](https://jsfiddle.net/qw1jabsx/4/). Use the loop approach for reliability.

---
|

|
||||
## Use toSorted() Instead of sort() for Immutability
|
||||
|
||||
`.sort()` mutates the array in place, which can cause bugs with React state and props. Use `.toSorted()` to create a new sorted array without mutation.
|
||||
|
||||
**Incorrect (mutates original array):**
|
||||
|
||||
```typescript
|
||||
function UserList({ users }: { users: User[] }) {
|
||||
// Mutates the users prop array!
|
||||
const sorted = useMemo(
|
||||
() => users.sort((a, b) => a.name.localeCompare(b.name)),
|
||||
[users]
|
||||
)
|
||||
return <div>{sorted.map(renderUser)}</div>
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (creates new array):**
|
||||
|
||||
```typescript
|
||||
function UserList({ users }: { users: User[] }) {
|
||||
// Creates new sorted array, original unchanged
|
||||
const sorted = useMemo(
|
||||
() => users.toSorted((a, b) => a.name.localeCompare(b.name)),
|
||||
[users]
|
||||
)
|
||||
return <div>{sorted.map(renderUser)}</div>
|
||||
}
|
||||
```
|
||||
|
||||
**Why this matters in React:**
|
||||
|
||||
1. Props/state mutations break React's immutability model - React expects props and state to be treated as read-only
|
||||
2. Causes stale closure bugs - Mutating arrays inside closures (callbacks, effects) can lead to unexpected behavior
|
||||
|
||||
**Browser support (fallback for older browsers):**
|
||||
|
||||
`.toSorted()` is available in all modern browsers (Chrome 110+, Safari 16+, Firefox 115+, Node.js 20+). For older environments, use spread operator:
|
||||
|
||||
```typescript
|
||||
// Fallback for older browsers
|
||||
const sorted = [...items].sort((a, b) => a.value - b.value);
|
||||
```
|
||||
|
||||
**Other immutable array methods:**
|
||||
|
||||
- `.toSorted()` - immutable sort
|
||||
- `.toReversed()` - immutable reverse
|
||||
- `.toSpliced()` - immutable splice
|
||||
- `.with()` - immutable element replacement

## Use Activity Component for Show/Hide
|

|

Use React's `<Activity>` to preserve state/DOM for expensive components that frequently toggle visibility.
|

|
||||
**Usage:**
|
||||
|
||||
```tsx
|
||||
import { Activity } from 'react';
|

function Dropdown({ isOpen }: Props) {

<Activity mode={isOpen ? 'visible' : 'hidden'}>

</Activity>
|

);

## Animate SVG Wrapper Instead of SVG Element
|
||||
|
||||
Many browsers don't have hardware acceleration for CSS3 animations on SVG elements. Wrap SVG in a `<div>` and animate the wrapper instead.
|
||||
|
||||
**Incorrect (animating SVG directly - no hardware acceleration):**
|
||||
|
||||
```tsx
|

function LoadingSpinner() {

return (
|
||||
<svg className="animate-spin" width="24" height="24" viewBox="0 0 24 24">

||||
<circle cx="12" cy="12" r="10" stroke="currentColor" />
|
||||
</svg>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (animating wrapper div - hardware accelerated):**
|
||||
|
||||
```tsx
|
||||
function LoadingSpinner() {
|
||||
return (
|
||||
<div className="animate-spin">
|

<svg width="24" height="24" viewBox="0 0 24 24">

</div>

);
|
||||
}
|
||||
```
|
||||
|
||||
This applies to all CSS transforms and transitions (`transform`, `opacity`, `translate`, `scale`, `rotate`). The wrapper div allows browsers to use GPU acceleration for smoother animations.

## Hoist Static JSX Elements
|

|

Extract static JSX outside components to avoid re-creation.

**Incorrect (recreates element every render):**
|
||||
|

```tsx
|

function LoadingSkeleton() {

|

function Container() {

return <div>{loading && <LoadingSkeleton />}</div>;
|

}
|

```
|
||||
|
||||
**Correct (reuses same element):**
|
||||
|
||||
```tsx
|
||||
const loadingSkeleton = <div className="h-20 animate-pulse bg-gray-200" />;
|
||||
|

function Container() {

|

This is especially helpful for large and static SVG nodes, which can be expensive to recreate on every render.
|

**Note:** If your project has [React Compiler](https://react.dev/learn/react-compiler) enabled, the compiler automatically hoists static JSX elements and optimizes component re-renders, making manual hoisting unnecessary.

title: Prevent Hydration Mismatch Without Flickering

|
||||
## Prevent Hydration Mismatch Without Flickering
|
||||
|
||||
When rendering content that depends on client-side storage (localStorage, cookies), avoid both SSR breakage and post-hydration flickering by injecting a synchronous script that updates the DOM before React hydrates.
|
||||
|
||||
**Incorrect (breaks SSR):**
|
||||
|
||||
```tsx
|
||||
function ThemeWrapper({ children }: { children: ReactNode }) {
|
||||
// localStorage is not available on server - throws error
|
||||
const theme = localStorage.getItem('theme') || 'light';
|
||||
|
||||
return <div className={theme}>{children}</div>;
|
||||
}
|
||||
```
|
||||
|
||||
Server-side rendering will fail because `localStorage` is undefined.
|
||||
|
||||
**Incorrect (visual flickering):**
|
||||
|
||||
```tsx
|
||||
function ThemeWrapper({ children }: { children: ReactNode }) {
|
||||
const [theme, setTheme] = useState('light');
|
||||
|
||||
useEffect(() => {
|
||||
// Runs after hydration - causes visible flash
|
||||
const stored = localStorage.getItem('theme');
|
||||
if (stored) {
|
||||
setTheme(stored);
|
||||
}
|
||||
}, []);
|
||||
|
||||
return <div className={theme}>{children}</div>;
|
||||
}
|
||||
```
|
||||
|
||||
Component first renders with default value (`light`), then updates after hydration, causing a visible flash of incorrect content.
|
||||
|
||||
**Correct (no flicker, no hydration mismatch):**
|
||||
|
||||
```tsx
|
||||
function ThemeWrapper({ children }: { children: ReactNode }) {
|
||||
return (
|
||||
<>
|
||||
<div id="theme-wrapper">{children}</div>
|
||||
<script
|
||||
dangerouslySetInnerHTML={{
|
||||
__html: `
|
||||
(function() {
|
||||
try {
|
||||
var theme = localStorage.getItem('theme') || 'light';
|
||||
var el = document.getElementById('theme-wrapper');
|
||||
if (el) el.className = theme;
|
||||
} catch (e) {}
|
||||
})();
|
||||
`,
|
||||
}}
|
||||
/>
|
||||
</>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
The inline script executes synchronously before showing the element, ensuring the DOM already has the correct value. No flickering, no hydration mismatch.
|
||||
|
||||
This pattern is especially useful for theme toggles, user preferences, authentication states, and any client-only data that should render immediately without flashing default values.

In SSR frameworks (e.g., Next.js), some values are intentionally different on server vs client (random IDs, dates, locale/timezone formatting).

- **Error resilience**: Pending state correctly resets even if the transition throws
|

- **Better responsiveness**: Keeps the UI responsive during updates
|
||||
- **Interrupt handling**: New transitions automatically cancel pending ones

## Calculate Derived State During Rendering
|
||||
|
||||
If a value can be computed from current props/state, do not store it in state or update it in an effect. Derive it during render to avoid extra renders and state drift. Do not set state in effects solely in response to prop changes; prefer derived values or keyed resets instead.
|
||||

**Incorrect (redundant state and effect):**

||||
|

```tsx

function Form() {

const [firstName, setFirstName] = useState('First');
|
||||
const [lastName, setLastName] = useState('Last');
|
||||
const [fullName, setFullName] = useState('');
|
||||
|
||||
useEffect(() => {
|
||||
setFullName(firstName + ' ' + lastName);
|
||||
}, [firstName, lastName]);
|
||||
|
||||
return <p>{fullName}</p>;
|
||||
}
|

```

**Correct (derive during render):**

const [firstName, setFirstName] = useState('First');
|

const [lastName, setLastName] = useState('Last');

}

|

|
||||
## Use Functional setState Updates
|
||||
|
||||
When updating state based on the current state value, use the functional update form of setState instead of directly referencing the state variable. This prevents stale closures, eliminates unnecessary dependencies, and creates stable callback references.
|
||||
|
||||
**Incorrect (requires state as dependency):**
|
||||
|
||||
```tsx
|
||||
function TodoList() {
|
||||
const [items, setItems] = useState(initialItems);
|
||||
|
||||
// Callback must depend on items, recreated on every items change
|
||||
const addItems = useCallback(
|
||||
(newItems: Item[]) => {
|
||||
setItems([...items, ...newItems]);
|
||||
},
|
||||
[items],
|
||||
); // ❌ items dependency causes recreations
|
||||
|
||||
// Risk of stale closure if dependency is forgotten
|
||||
const removeItem = useCallback((id: string) => {
|
||||
setItems(items.filter((item) => item.id !== id));
|
||||
}, []); // ❌ Missing items dependency - will use stale items!
|
||||
|
||||
return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />;
|
||||
}
|
||||
```
|
||||
|
||||
The first callback is recreated every time `items` changes, which can cause child components to re-render unnecessarily. The second callback has a stale closure bug—it will always reference the initial `items` value.
|
||||
|
||||
**Correct (stable callbacks, no stale closures):**
|
||||
|
||||
```tsx
|
||||
function TodoList() {
|
||||
const [items, setItems] = useState(initialItems);
|
||||
|
||||
// Stable callback, never recreated
|
||||
const addItems = useCallback((newItems: Item[]) => {
|
||||
setItems((curr) => [...curr, ...newItems]);
|
||||
}, []); // ✅ No dependencies needed
|
||||
|
||||
// Always uses latest state, no stale closure risk
|
||||
const removeItem = useCallback((id: string) => {
|
||||
setItems((curr) => curr.filter((item) => item.id !== id));
|
||||
}, []); // ✅ Safe and stable
|
||||
|
||||
return <ItemsEditor items={items} onAdd={addItems} onRemove={removeItem} />;
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
|
||||
1. **Stable callback references** - Callbacks don't need to be recreated when state changes
|
||||
2. **No stale closures** - Always operates on the latest state value
|
||||
3. **Fewer dependencies** - Simplifies dependency arrays and reduces memory leaks
|
||||
4. **Prevents bugs** - Eliminates the most common source of React closure bugs
|
||||
|
||||
**When to use functional updates:**
|
||||
|
||||
- Any setState that depends on the current state value
|
||||
- Inside useCallback/useMemo when state is needed
|
||||
- Event handlers that reference state
|
||||
- Async operations that update state
|
||||
|
||||
**When direct updates are fine:**
|
||||
|
||||
- Setting state to a static value: `setCount(0)`
|
||||
- Setting state from props/arguments only: `setName(newName)`
|
||||
- State doesn't depend on previous value
|
||||
|
||||
**Note:** If your project has [React Compiler](https://react.dev/learn/react-compiler) enabled, the compiler can automatically optimize some cases, but functional updates are still recommended for correctness and to prevent stale closure bugs.

title: Use Lazy State Initialization

tags: react, hooks, useState, performance, initialization

|

|

## Use Lazy State Initialization
|
||||
|
||||
Pass a function to `useState` for expensive initial values. Without the function form, the initializer runs on every render even though the value is only used once.
|
||||
|
||||
**Incorrect (runs on every render):**
|
||||
|
||||
```tsx
|
||||
function FilteredList({ items }: { items: Item[] }) {
|
||||
// buildSearchIndex() runs on EVERY render, even after initialization
|
||||
const [searchIndex, setSearchIndex] = useState(buildSearchIndex(items));
|
||||
const [query, setQuery] = useState('');
|
||||
|
||||
// When query changes, buildSearchIndex runs again unnecessarily
|
||||
return <SearchResults index={searchIndex} query={query} />;
|
||||
}
|
||||
|
||||
function UserProfile() {
|
||||
// JSON.parse runs on every render
|
||||
const [settings, setSettings] = useState(JSON.parse(localStorage.getItem('settings') || '{}'));
|
||||
|
||||
return <SettingsForm settings={settings} onChange={setSettings} />;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (runs only once):**
|
||||
|
||||
```tsx
|
||||
function FilteredList({ items }: { items: Item[] }) {
|
||||
// buildSearchIndex() runs ONLY on initial render
|
||||
const [searchIndex, setSearchIndex] = useState(() => buildSearchIndex(items));
|
||||
const [query, setQuery] = useState('');
|
||||
|
||||
return <SearchResults index={searchIndex} query={query} />;
|
||||
}
|
||||
|
||||
function UserProfile() {
|
||||
// JSON.parse runs only on initial render
|
||||
const [settings, setSettings] = useState(() => {
|
||||
const stored = localStorage.getItem('settings');
|
||||
return stored ? JSON.parse(stored) : {};
|
||||
});
|
||||
|
||||
return <SettingsForm settings={settings} onChange={setSettings} />;
|
||||
}
|
||||
```
|
||||
|
||||
Use lazy initialization when computing initial values from localStorage/sessionStorage, building data structures (indexes, maps), reading from the DOM, or performing heavy transformations.
|
||||
|
||||
For simple primitives (`useState(0)`), direct references (`useState(props.value)`), or cheap literals (`useState({})`), the function form is unnecessary.

## Extract Default Non-primitive Parameter Value from Memoized Component to Constant
|
||||
|
||||
When memoized component has a default value for some non-primitive optional parameter, such as an array, function, or object, calling the component without that parameter results in broken memoization. This is because new value instances are created on every rerender, and they do not pass strict equality comparison in `memo()`.

To address this issue, extract the default value into a constant.
