useIdle Hook

useIdle is a React hook designed to detect user inactivity or idle time in applications. It triggers a state change after a specified period of inactivity, making it useful for actions like auto-logout or activity pausing.

Features

• Idle Time Detection: Tracks user inactivity and changes state after a set period.
• Activity Monitoring: Resets the idle timer upon user interactions like mouse movement, keypresses, and scrolling.
• SSR Compatibility: Safely handles server-side rendering by checking for the window object.
• Configurable Idle Duration: Allows setting a custom duration to define user inactivity.

Usage

import React from 'react';
import { useIdle } from '@custom-react-hooks/all';
import { MoonIcon, SunIcon } from '@heroicons/react/24/solid';


const IdleComponent = () => {
  const isIdle = useIdle(1000);

  return (
    <div className="center">
      {isIdle ? (
        <div className="btns">
          <MoonIcon/>
          <p>Away</p>
        </div>
      ) : (
        <div className="btns">
          <SunIcon/>
          <p>Online</p>
        </div>
      )}
      <br />
      <p>To see the effect, do not move the mouse or touch the keyboard!</p>
    </div>
  );
};

export default IdleComponent;

In this example, the hook is used to detect when the user has been idle for more than 3 seconds.
