React useClickInside hook

React, Hooks, Effect, Event · Nov 16, 2020

Handles the event of clicking inside the wrapped component.

  • Create a custom hook that takes a ref and a callback to handle the 'click' event.
  • Use the useEffect() hook to append and clean up the click event.
  • Use the useRef() hook to create a ref for your click component and pass it to the useClickInside hook.
const useClickInside = (ref, callback) => {
  const handleClick = e => {
    if (ref.current && ref.current.contains( {
  React.useEffect(() => {
    document.addEventListener('click', handleClick);
    return () => {
      document.removeEventListener('click', handleClick);
const ClickBox = ({ onClickInside }) => {
  const clickRef = React.useRef();
  useClickInside(clickRef, onClickInside);
  return (
        border: '2px dashed orangered',
        height: 200,
        width: 400,
        display: 'flex',
        justifyContent: 'center',
        alignItems: 'center'
      <p>Click inside this element</p>

  <ClickBox onClickInside={() => alert('click inside')} />,
