How to use the usePageVisibility hook for tracking changes in page visibility in Next.js

To use the usePageVisibility hook for tracking changes in page visibility in a Next.js application, you first need to create the hook or import it from a library that provides it. Then, you can use it within your components to monitor changes in the visibility state of the page.

Here's how you can implement it:

1. Install the necessary library if it's not already installed. You can use libraries like react-page-visibility or implement the hook yourself.

bashCopy code
npm install react-page-visibility

2. Create the usePageVisibility hook or import it from the library:

javascriptCopy code
// usePageVisibility.js

import { useEffect, useState } from 'react';

export const usePageVisibility = () => {
  const [isVisible, setIsVisible] = useState(true);

  useEffect(() => {
    const handleVisibilityChange = () => {
      setIsVisible(!document.hidden);
    };

    document.addEventListener('visibilitychange', handleVisibilityChange);

    return () => {
      document.removeEventListener('visibilitychange', handleVisibilityChange);
    };
  }, []);

  return isVisible;
};

3. Now, you can use this hook in your Next.js components to track changes in page visibility:

javascriptCopy code
// YourComponent.js

import { usePageVisibility } from '../hooks/usePageVisibility';

const YourComponent = () => {
  const isVisible = usePageVisibility();

  useEffect(() => {
    if (isVisible) {
      console.log('Page is visible');
    } else {
      console.log('Page is hidden');
    }
  }, [isVisible]);

  return (
    <div>
      {/* Your component JSX */}
    </div>
  );
};

export default YourComponent;

In this example, the usePageVisibility hook is used to track changes in the page visibility. It updates the isVisible state whenever the visibility changes, and then you can perform any actions or side effects based on the visibility state in your component.

Remember to import and use this component wherever you want to track page visibility within your Next.js application.
