Learn how to build a secure, scalable authentication system from scratch! In this step-by-step tutorial, I’ll guide you through creating a Node.js backend with JWT (JSON Web Tokens), role-based authorization, and REST API best practices. Then, we’ll integrate it seamlessly into a Flutter mobile app for user signup, login, and protected routes.

Download Node.js : https://nodejs.org/en
Download Postman : https://www.postman.com/downloads/
MongoDB Server : https://www.postman.com/downloads/
MongoDB Compass : https://www.mongodb.com/try/download/...

📌 What You’ll Learn:
✅ Build a Node.js/Express.js backend with MongoDB
✅ Implement JWT authentication & authorization (Admin/User roles)
✅ Secure APIs with middleware and password hashing (bcrypt)
✅ Handle token refresh, cookies, and security best practices
✅ Integrate the backend with a Flutter app (Dart) for seamless auth flows
✅ Error handling, validation, and testing with Postman

Perfect for developers diving into full-stack development, authentication systems, or Flutter+Node.js integration.
