🧩 Node.js + Express + MongoDB + JWT Auth

A simple backend for managing posts or notes with user authentication using JWT and MongoDB Atlas.
Includes registration, login, and protected routes.

💡 Future goals:

• Multi-role access control (admin, super-admin, user)
• API documentation via Swagger
• Docker setup for containerized deployment

---

🛠️ Tech Stack

• Node.js + Express.js
• MongoDB Atlas (Mongoose ODM)
• JWT (jsonwebtoken) for authentication
• bcryptjs for password hashing
• dotenv for environment variables
• Jest or Vitest (for testing)
• GitHub Actions (for CI)
