## Preload Based on User Intent
|
|
|
|
Preload heavy bundles before they're needed to reduce perceived latency.
|
|
|
|
**Example (preload on hover/focus):**
|
|
|
|
```tsx
|
|
function EditorButton({ onClick }: { onClick: () => void }) {
|
|
const preload = () => {
|
|
if (typeof window !== 'undefined') {
|
|
void import('./monaco-editor');
|
|
}
|
|
};
|
|
|
|
return (
|
|
<button onMouseEnter={preload} onFocus={preload} onClick={onClick}>
|
|
Open Editor
|
|
</button>
|
|
);
|
|
}
|
|
```
|
|
|
|
**Example (preload when feature flag is enabled):**
|
|
|
|
```tsx
|
|
function FlagsProvider({ children, flags }: Props) {
|
|
useEffect(() => {
|
|
if (flags.editorEnabled && typeof window !== 'undefined') {
|
|
void import('./monaco-editor').then((mod) => mod.init());
|
|
}
|
|
}, [flags.editorEnabled]);
|
|
|
|
return <FlagsContext.Provider value={flags}>{children}</FlagsContext.Provider>;
|
|
}
|
|
```
|
|
|
|
The `typeof window !== 'undefined'` check prevents bundling preloaded modules for SSR, optimizing server bundle size and build speed.
