useBeforeUnMount

useBeforeUnMount is a React equivalent adaptation of Vue's onBeforeUnmount, which triggers a callback before a component is unmounted.

Basic Usage

This hook is suitable for placing logic that "executes immediately before leaving the page", such as stopping animations, tracking events, and unbinding resources.

useBeforeUnMount(() => {
  console.log('before unmount');
});

This code will not execute during the mount and update phases, only when unmounting.

API

function useBeforeUnMount(fn: EffectCallback): void;

Notes

• Triggered only during the unmount phase.
• The current implementation does not consume the returned cleanup function.
• Based on the cleanup path of useLayoutEffect.
