react-use-event-hook

Same as React's useCallback, but returns a stable reference.

This library is a user-land implementation of the useEvent hook, proposed in this RFC.

Installation

1npm install react-use-event-hook

Usage

(this example was copied from the RFC)

You can wrap any event handler into useEvent.

1import useEvent from 'react-use-event-hook';
2
3function Chat() {
4  const [text, setText] = useState('');
5
6  const onClick = useEvent(() => {
7    sendMessage(text);
8  });
9
10  return <SendButton onClick={onClick} />;
11}

The code inside useEvent “sees” the props/state values at the time of the call. The returned function has a stable identity even if the props/state it references change. There is no dependency array.
