# use-latest-callback
|
|
|
|
React hook which returns the latest callback without changing the reference.
|
|
|
|
This is useful for scenarios such as event listeners where you may not want to resubscribe when the callback changes.
|
|
|
|
## Installation
|
|
|
|
Open a Terminal in the project root and run:
|
|
|
|
```sh
|
|
npm install use-latest-callback
|
|
```
|
|
|
|
## Usage
|
|
|
|
The `useLatestCallback` hook accepts a function as its argument and returns a function that preserves its reference across renders.
|
|
|
|
```js
|
|
import useLatestCallback from 'use-latest-callback';
|
|
|
|
// ...
|
|
|
|
function MyComponent() {
|
|
const callback = useLatestCallback((value) => {
|
|
console.log('Changed', value);
|
|
});
|
|
|
|
React.useEffect(() => {
|
|
someEvent.addListener(callback);
|
|
|
|
return () => someEvent.removeListener(callback);
|
|
}, [callback]);
|
|
|
|
return <>{/* whatever */}</>;
|
|
}
|
|
```
|
|
|
|
It's important to note that the callback is not intended to be called during the render phase. Only call the callback in response to an event.
