@figliolia/react-hooks/dist/mjs/Hooks/useUnmount.js

A small collection of simple React Hooks you're probably rewriting on a regular basis

import { useEffect, useRef } from "react";
export const useUnmount = (onUnmount) => {
    const callback = useRef(onUnmount);
    callback.current = onUnmount;
    useEffect(() => {
        const { current: fn } = callback;
        return () => fn();
    }, []);
};
