useUnmounted

useUnmounted is a React adaptation of Vue's onUnmounted, which executes when a component is unmounted.

Basic Usage

This hook is suitable for placing "cleanup logic on leaving", such as reporting logs and disconnecting connections.

useUnmounted(async () => {
  await reportLeave();
});

It will not run during the mount and update phases, only triggering when unmounted.

API

function useUnmounted(fn: EffectCallback): void;

Notes

• Executes only when unmounted.
• Asynchronous logic can be written.
• Based on useEffect cleanup.
