http://localhost:3000/api

Available Endpoints

• GET /health - Health check
• POST /auth/login - User authentication
• GET /users - Get all users (requires authentication)
• POST /users - Create new user (requires authentication)

Authentication

Include JWT token in Authorization header:

Authorization: Bearer <your-jwt-token>

Request Headers

x-request-id: MODULE_ACTION_UUID (optional)
x-correlation-id: <correlation-id> (optional)

🧪 Testing

# Run permission tests
npm run test:permissions

# Run all tests
npm test

🚀 Deployment

# Build for production
npm run build

# Start production server
npm start

# Docker deployment
npm run docker:build
npm run docker:run

🔧 Configuration

Environment Variables

• NODE_ENV - Environment (development/production)
• PORT - Server port
• MONGODB_URI - MongoDB connection string
• JWT_SECRET - JWT signing secret
• JWT_EXPIRES_IN - JWT expiration time

Database Configuration

• MongoDB with Mongoose ODM

📖 Examples

Creating a New Module

# Generate complete module structure
npm run generate:module -- --name=products --description="Product management"

# This creates:
# - Entity files (interfaces and schemas)
# - Service with CRUD operations
# - Controller with HTTP handlers
# - Routes with permission middleware
# - Swagger documentation

Permission Setup

# Initialize permission system
npm run setup:permissions

# Create admin user
npm run setup:admin
