useTabChangeDetect

useTabChangeDetect is a custom React hook that allows you to detect tab switches or changes in visibility, triggering a callback when the specified number of tab switches has occurred.

Installation

You can install useTabChangeDetect via npm or yarn:

npm install use-tab-change-detect

or

yarn add use-tab-change-detect

Usage

To use the useTabChangeDetect hook, simply call it inside your component and provide a callback that should be triggered when the tab switch count exceeds the timesAllowed threshold. Optionally, you can set a custom value for timesAllowed (default is 0).

Example

import React, { useState } from 'react';
import useTabChangeDetect from 'use-tab-change-detect';

const App = () => {
  const [message, setMessage] = useState("You're on the current tab!");

  const handleTabChange = () => {
    setMessage("Tab switched!");
  };

  useTabChangeDetect(handleTabChange, 2);  // Set to trigger after 2 tab switches

  return (
    <div>
      <h1>{message}</h1>
      <p>Switch tabs and see the magic!</p>
    </div>
  );
};

export default App;

In the example above, the handleTabChange function is triggered after the tab is switched twice.

How It Works

• useTabChangeDetect listens to both the visibilitychange and blur events to detect tab changes.
• When a tab switch occurs (i.e., when the tab is either hidden or blurred), the hook increments a count (tabSwitchCount).
• Once the tabSwitchCount exceeds the specified threshold (timesAllowed), the callback function is triggered.

Parameters

• callback (required): A function that is called when the number of tab switches exceeds timesAllowed.
• timesAllowed (optional, default 0): The number of tab switches that need to occur before the callback is invoked. This value defaults to 0, meaning the callback will trigger on the first tab switch.

Cleanup

The hook automatically cleans up event listeners when the component using the hook is unmounted, ensuring there are no memory leaks.
