### 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.

Next.js is a React framework designed for creating full-stack web applications. With Next.js, you utilize React to construct user interfaces while benefiting from additional features and optimizations provided by the framework.

Let's discuss what you need to learn before diving into the Next.js framework, what to expect from this course, and what you'll build.

We will set up the project, inspect ways to add styling to our app and cover visual aspects such as images, fonts, pages, and layouts.

Learn how to easily create and manage a new view for your app and navigate through all pages seamlessly with an incorporated routing system.

Deploy the Next.js app using GitHub and Vercel accounts. Additionally, establish a database to supply the app with the necessary data.

Consider how to obtain and show data to the user clearly and efficiently.

Discover how to implement modern web features such as pagination, CRUD operations, global search, form validation, and more.
