Next.js 15 Authentication: NextAuth, TypeScript, MailTrap

Create a Next.js authentication project with next-auth, using TypeScript and Tailwind CSS; install mongoose and bcrypt, build core pages and a header, and run the dev server.

Create a responsive header with a navbar using next/link, linking home, login, and register pages, integrated into layout.tsx and demonstrated with routing to /home, /login, and /register.

Create a signup user interface for the register page with an email and password form, a sign-up button, and a login link, plus a dark login with GitHub option.

Create a responsive login and registration UI in a Next.js project by updating the login page, adding a sign in button, linking to the register page, and ensuring proper spacing.

Create a MongoDB-backed database for next auth by configuring an env file, connecting with Mongoose to the Mongo URL, and defining a user model and register route.

Copy and save the db.js code to fix registration errors, then resubmit signup to see a 200 status and login redirect, while MongoDB shows the new user with hashed password.

Learn how to implement user login with next-auth in a Next.js project, configure providers including GitHub, set up api/auth routes, connect to a database, and validate credentials with bcrypt.

Set up a client side store and session provider to manage user state across the app with next auth, get server session, and routing in Next.js 15.

Switch to a client component to fix a server component error, enable login with session status, and redirect to /home on authentication, while showing the user email in the navigation.

Learn to server render the home page with next-auth by using getServerSession, redirecting unauthenticated users to /login, and configuring NEXTAUTH_URL and NEXTAUTH_SECRET.

Edit navbar to reflect authentication status using next-auth's useSession; show login or register links when not signed in, or display the user email with a logout button when signed in.
