useUnmountPromise.md

useUnmountPromise

A life-cycle hook that provides a higher order promise that does not resolve if component un-mounts.

Usage

import useUnmountPromise from 'react-use/lib/useUnmountPromise';

const Demo = () => {
  const mounted = useUnmountPromise();
  useEffect(async () => {
    await mounted(someFunction()); // Will not resolve if component un-mounts.
  });
};

Reference

const mounted = useUnmountPromise();

mounted(promise);
mounted(promise, onError);

• onError — if promise rejects after the component is unmounted, onError callback is called with the error.
