How to create a custom hook for handling user interactions with the browser's location in Next.js

To create a custom hook for handling user interactions with the browser's location in Next.js, you can utilize the useRouter hook provided by Next.js along with React's useState hook. Here's a step-by-step guide:

1. Install Dependencies: Ensure you have Next.js installed and set up in your project.

2. Create the Custom Hook: You can create a custom hook named useLocation:

javascriptCopy code
// hooks/useLocation.js

import { useRouter } from 'next/router';
import { useEffect, useState } from 'react';

const useLocation = () => {
  const router = useRouter();
  const [location, setLocation] = useState(router.asPath);

  useEffect(() => {
    const handleRouteChange = (url) => {
      setLocation(url);
    };

    // Subscribe to router events
    router.events.on('routeChangeComplete', handleRouteChange);

    // Unsubscribe from router events when component unmounts
    return () => {
      router.events.off('routeChangeComplete', handleRouteChange);
    };
  }, [router.events]);

  return location;
};

export default useLocation;

3. Use the Custom Hook in Your Components: You can now import and use the useLocation hook in your Next.js components:

javascriptCopy code
// components/MyComponent.js

import React from 'react';
import useLocation from '../hooks/useLocation';

const MyComponent = () => {
  const location = useLocation();

  return (
    <div>
      Current Location: {location}
    </div>
  );
};

export default MyComponent;

4. Testing: You can now use MyComponent in your pages or other components. It will automatically update whenever the browser's location changes.

This custom hook subscribes to router events provided by Next.js and updates the location state whenever the route changes. It then returns the current location, which can be used in components to reactively update UI based on the browser's location.
