useLongPress Hook

The useLongPress hook is designed for adding long press interactions to elements in React applications. It provides a flexible way to handle long press events with customizable thresholds and callbacks.

Features

• Customizable Long Press Duration: Set a threshold for how long the press should last to trigger the event.
• Multiple Event Callbacks: Options for onStart, onFinish, and onCancel callbacks.
• Support for Mouse and Touch: Works with both mouse and touch events.
• SSR Safe: Can be safely used in server-side rendered applications.

Usage

import React, { useState } from 'react';
import { useLongPress } from '@custom-react-hooks/all';

const LongPressTestComponent = () => {
  const [status, setStatus] = useState('Ready');

  const longPressCallback = () => {
    setStatus('Finished');
  };

  const longPressEvents = useLongPress(longPressCallback, {
    threshold: 500,
    onStart: () => setStatus('Started'),
    onFinish: () => setStatus('Finished'),
    onCancel: () => setStatus('Cancelled'),
  });

  return (
    <div>
      <button {...longPressEvents}>
        Press and Hold
      </button>
      <p>
        Status: <span>{status}</span>
