Configuring Authentication and Protecting Routes

Back to the Project

1. Adding Custom Sign-in Page

Create an auth.config.ts file at the project root with this content:

This specifies a custom sign-in page route (/login) using the pages option.

2. Protecting Routes with Middleware

Extend auth.config.ts to include route protection logic. Users are redirected to the login page if they try to access the dashboard without being logged in.

3. Middleware

Create a middleware.ts file to initialize NextAuth.js and protect routes using the specified configuration.

We set up a custom sign-in page and added logic to protect routes. The Middleware ensures that protected routes won't render until authentication is verified, improving both security and performance.
