Package Exports
- use-callback-ref
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (use-callback-ref) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
use-callback-ref
Keep in mind that useRef doesn't notify you when its content changes. Mutating the .current property doesn't cause a re-render. If you want to run some code when React attaches or detaches a ref to a DOM node, you may want to use
a callback ref instead.... useCallbackRef instead.
API
API is 99% compatible with React createRef
and useRef
, and just adds another argument - callback
,
which would be called on ref update.
- (React.createRef)
createCallbackRef(callback)
- would call provided callback when ref is changed. - (React.useRef)
useRef(initialValue, callback)
- would call provided callback when ref is changed.
import {useRef, createRef, useState} from 'react';
import {useCallbackRef, createCallbackRef} from 'use-callback-ref';
const Component = () => {
const [,forceUpdate] = useState();
// I dont need callback when ref changes
const ref = useRef(null);
// but sometimes - it could be what you need
const anotherRef = useCallbackRef(null, () => forceUpdate());
useEffect( () => {
// now it's just possible
}, [anotherRef.current]) // react to dom node change
}
