preact-missing-hooks/dist/useMutationObserver.d.ts

A lightweight, extendable collection of missing React-like hooks for Preact — plus fresh, powerful new ones designed specifically for modern Preact apps.

import { RefObject } from 'preact';
export type UseMutationObserverOptions = MutationObserverInit;
/**
 * A Preact hook to observe DOM mutations using MutationObserver.
 * @param target - The element to observe.
 * @param callback - Function to call on mutation.
 * @param options - MutationObserver options.
 */
export declare function useMutationObserver(targetRef: RefObject<HTMLElement | null>, callback: MutationCallback, options: MutationObserverInit): void;
