To create a custom hook for handling user interactions with the browser's network status in Next.js, you can use the useEffect hook to listen for online/offline events and update the state accordingly. Here's a basic example:

jsx
import { useState, useEffect } from 'react';

const useNetworkStatus = () => {
  const [isOnline, setIsOnline] = useState(navigator.onLine);

  useEffect(() => {
    const handleOnline = () => setIsOnline(true);
    const handleOffline = () => setIsOnline(false);

    window.addEventListener('online', handleOnline);
    window.addEventListener('offline', handleOffline);

    return () => {
      window.removeEventListener('online', handleOnline);
      window.removeEventListener('offline', handleOffline);
    };
  }, []);

  return isOnline;
};

export default useNetworkStatus;

This custom hook, useNetworkStatus, returns a boolean value indicating whether the browser is currently online or offline.

To use this custom hook in your Next.js application, you can import it and call it within your component:

jsx
import React from 'react';
import useNetworkStatus from '../hooks/useNetworkStatus';

const MyComponent = () => {
  const isOnline = useNetworkStatus();

  return (
    <div>
      <h1>Network Status</h1>
      <p>{isOnline ? 'Online' : 'Offline'}</p>
    </div>
  );
};

export default MyComponent;

This component will render "Online" or "Offline" depending on the current network status.

Remember to create a folder named hooks in your project directory and place the useNetworkStatus hook inside a file, such as useNetworkStatus.js, within that folder. This ensures proper organization of your custom hooks.
