react-use-bound-callback-hook

A useBoundCallback hook for React. Similar to useCallback but binds the arguments instead of relying on closures.

What it does:

1. Memoizes a callback function based on arguments array and context passed
2. If callback function is not previously bound, binds it to passed in arguments and context
3. If callback function is previously bound, checks if passed in arguments and context differ from last bound ones.
4. If they differ, rebinds and returns rebound callback.
5. Else returns previously bound callback.

Installation

yarn add react-use-bound-callback-hook

npm install react-use-bound-callback-hook

Usage:

import { useBoundCallback } from 'react-use-bound-callback-hook';
 
function onChange(setText, ev) {
    setText(ev.currentValue.text);
};
 
function SomeComponent(props) {
    const [text, setText] = useState('');
 
    return (
        <input type="text" onChange={useBoundCallback(onChange, [setText])} />
    );
}

useBoundCallback takes three arguments:

• callback - The callback function to be memoized
• arguments - The arguments to be bound to the callback function
• context - The context to execute the callback function as i.e. the value of this inside the callback. Optional. Default null.
