useUnmountEffect

Run an effect exactly once, when the component unmounts.

Usage#

import { useUnmountEffect } from '@primereact/hooks/use-unmount-effect';

useUnmountEffect(() => {
    socket.close();
});

Equivalent to useEffect(() => cleanup, []), expressed as the cleanup by itself. Reads clearer when the mount path has nothing to do.

function useUnmountEffect(effect: React.EffectCallback): void;
