Advanced tools
Package description
The npm package 'use-composed-ref' provides a React hook that allows you to compose multiple refs (both React ref objects and callback refs) into a single callback ref. This is particularly useful in scenarios where you need to attach multiple refs to a single element, such as when using third-party libraries that require a ref, while also maintaining your own ref for the same element.
Composing multiple refs
This feature allows the user to combine multiple refs into one, which can then be attached to a React element. In the code sample, `myRef` and `externalRef` are composed into a single ref `composedRef`, which is then used in a div element.
import React, { useRef } from 'react';
import useComposedRef from 'use-composed-ref';
function MyComponent() {
const myRef = useRef(null);
const externalRef = useRef(null);
const composedRef = useComposedRef(myRef, externalRef);
return <div ref={composedRef}>Hello, world!</div>;
}Similar to 'use-composed-ref', 'react-merge-refs' is another npm package that provides functionality to merge multiple React refs into one. It supports both callback and object refs and is used in a similar way. The main difference lies in the implementation details and possibly in the specific use cases each package is optimized for.
This package offers a way to create a stable callback ref. While it primarily focuses on creating individual callback refs rather than composing multiple refs, it shares the concept of managing refs in a more flexible way, similar to what 'use-composed-ref' offers.
