next js redirect if not logged in

To redirect if a user is not logged in using Next.js, you can follow these steps:

1. Create a higher-order component (HOC) to check if the user is authenticated.
2. Inside the HOC, use the useEffect hook to check if the user is logged in when the component mounts.
3. If the user is not logged in, use the useRouter hook to redirect to the login page.
4. Wrap the pages that require authentication with the HOC to protect them from unauthorized access.

I hope this helps!
