## React 19 API Changes
|
|
|
|
> **⚠️ 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()`.
