How to go back to previous route after authentication in nextjs

To go back to the previous route after authentication in Next.js, you can follow these steps:

1. Use the useRouter hook from the next/router package to access the router object in your component.

2. Before redirecting the user to the login page for authentication, save the current route using the asPath property of the router object.

3. After successful authentication, use the replace method of the router object to replace the current route with the previously saved route using the saved path.

By following these steps, you can ensure that the user is redirected back to the previous route after successful authentication in Next.js.
