express-jwt-mongodb

This npm package provides a CLI tool to quickly scaffold a secure Express server with JWT authentication and MongoDB integration. It sets up a basic project structure with essential security features already implemented.

Features

• Express server setup with security middleware
• MongoDB integration
• JWT-based authentication
• Basic user registration and login
• Protected route example
• Organized folder structure (MVC pattern)

Prerequisites

Before you begin, ensure you have met the following requirements:

• Node.js (v12.0.0 or higher)
• MongoDB (Make sure it's installed and running)

Installation

To use this package, you can run it directly using npx:

npx express-jwt-mongodb my-project-name

Or you can install it globally:

npm install -g express-jwt-mongodb
express-jwt-mongodb my-project-name

Usage

After running the scaffold command, navigate to your new project directory:

cd my-project-name

Install the dependencies:

npm install

Create a .env file in the root directory and add the following:

MONGODB_URI=mongodb://localhost:27017/your_database_name
JWT_SECRET=your_jwt_secret_key
PORT=3000

Replace your_database_name with your desired database name and your_jwt_secret_key with a strong, unique secret key.

To start the server, run:

npm start

The server will start on the port specified in your .env file (default is 3000).

API Endpoints

1. Register a new user:

   • POST /api/auth/register
   • Body: { "username": "your_username", "password": "your_password" }

2. Login:

   • POST /api/auth/login
   • Body: { "username": "your_username", "password": "your_password" }

3. Access protected route (requires authentication):

   • GET /api/protected
   • Header: Authorization: Bearer your_jwt_token

Folder Structure

The scaffolded project will have the following structure:

my-project-name/
├── controllers/
│   └── authController.js
├── routes/
│   └── auth.js
├── models/
│   └── User.js
├── middleware/
│   └── auth.js
├── server.js
├── .env
└── package.json

Customization

You can extend the scaffolded project by:

1. Adding more routes in the routes/ directory
2. Creating new controllers in the controllers/ directory
3. Adding new models in the models/ directory
4. Implementing additional middleware in the middleware/ directory

Security Features

This scaffold includes several security features:

• CORS (Cross-Origin Resource Sharing)
• Helmet (sets various HTTP headers)
• Rate limiting (prevents brute-force attacks)
• JWT authentication (secures routes)
• Password hashing (using bcrypt)
