useEventListener()

useEventListener<KW, KH, KM, T>(eventName, handler, element?, options?, debounce?): void

Defined in: src/hooks/dom/useEventListener.ts:61

A custom React hook for attaching an event listener to a target element with automatic cleanup. This hook is useful for adding event listeners to DOM elements or the window object. It also supports optional debouncing to limit how often the handler is invoked.

}, buttonRef);

Example 3: Attach a document event listener

const documentRef = useRef<Document>(document);
useEventListener('keydown', (event) => {
  console.log('Key pressed:', event.key);
}, documentRef, { capture: true });

const mediaQueryListRef = useRef(window.matchMedia('(max-width: 600px)'));
useEventListener(
