Secure JWT Authentication API

This project is a backend API that implements JWT (JSON Web Token) authentication. It's built with Express.js, MongoDB, and Mongoose.

Features

• User registration and login
• Secure password hashing with bcrypt
• JWT for user authentication
• Middleware for route protection and authorization

Getting Started

1. Clone the repository
2. Install dependencies with npm install
3. Create your config.env file add your MongoDB connection string and JWT secret, like so:
   DB=your_mongodb_uri
JWT_SECRET=your_jwt_secret
JWT_EXPIRES_IN=90d
JWT_COOKIE_EXPIRES_IN=90
   
4. Run the application with npm start

Usage

The main entry point of the application is src/app.js. This file sets up the Express application, mounts the auth router, and handles any unhandled routes.

• Auth Router: Defines the routes for user authentication. These routes use the auth controller and auth middleware.

• Auth Controller: Contains the logic for user registration and login. It uses the User model to interact with the MongoDB database.

• Auth Middleware: Used to protect routes. It checks if the request has a valid JWT and if the user associated with the JWT exists.

• User Model: Defines the schema for users and includes methods for password hashing and checking if a password has been changed after a JWT was issued.

Feel at liberty to examine the code and employ it as a starting point for your individual projects.
