🚀 Next-Auth with Express, MongoDB, and TailwindCSS

This repository showcases a full-stack authentication solution, combining:

• Next.js for frontend development, styled with the aesthetics of TailwindCSS. 🎨
• Express.js for backend API routes and logic. 🖥️
• MongoDB as the go-to database. 🗄️

🏛 Architecture

• Frontend: Combining Next.js, TailwindCSS, and the next-auth package, we offer a seamless user experience and session management.

• Backend: Express.js provides our API routes handling user registration, login, JWT creation, and validation. 🎩

• Database: MongoDB ensures secure storage of user details. Passwords are stored securely, hashed with bcrypt. 🔐

🔒 How Authentication Works

1. User Registration:

   • Input email and password. 📧
   • Passwords are hashed using bcrypt before storage.
   • Successful registration redirects to the login page. 👣

2. User Login:

   • Provide your email and password. 🌐
   • Express.js verifies credentials against MongoDB.
   • On successful authentication, receive a JWT as an HttpOnly cookie. 🍪

3. Authenticated Requests:

   • For authenticated requests, the browser sends the JWT cookie automatically. 🌍
   • Express verifies the JWT on each request.

4. Session Management on Frontend:

   • next-auth manages user sessions on the frontend. 🌈
   • Use utilities like useSession to render content based on authentication state. 📊

5. Logout:

   • Logout to end the session. 🔚
   • The JWT cookie is cleared. 🔄
