useDebounce()

This is helpful if you need to call an API as a user is typing, and you don't want to make too many calls.

import { RefObject, useEffect } from 'react';

export default function useOnClickOutside<T extends HTMLElement = HTMLElement>(
  refs: RefObject<T>[],
  handler: (event: MouseEvent) => void
) {
  useEffect(() => {
    const listener = (event: Event) => {
      if (
        refs.find(
          (ref) => ref.current && ref.current.contains(event.target as Node)
        )
      ) {
        return;
      }
      handler(event as unknown as MouseEvent);
    };
    document.addEventListener('mousedown', listener);
    document.addEventListener('touchstart', listener);
    return () => {
      document.removeEventListener('mousedown', listener);
      document.removeEventListener('touchstart', listener);
    };
  }, [refs, handler]);
}
