Quick Start

bash
# Navigate to the project
cd /workspaces/claude-code-flow/examples/05-swarm-apps/rest-api-advanced

# Run the quick start script
./scripts/quick-start.sh

# Or manually:
# 1. Copy environment variables
cp .env.example .env

# 2. Install dependencies
npm install

# 3. Start services with Docker
docker-compose up -d

# 4. Seed the database
npm run seed

# 5. Start the development server
npm run dev

Available Services

Testing

bash
# Run all tests
npm test

# Run with coverage
npm run test:coverage

# Run specific test suite
npm test auth.test.js

# Run in watch mode
npm run test:watch

Key Endpoints

Authentication

  • POST /api/v1/auth/register - User registration
  • POST /api/v1/auth/login - User login
  • POST /api/v1/auth/logout - User logout
  • POST /api/v1/auth/refresh - Refresh tokens
  • POST /api/v1/auth/forgot-password - Password reset request
  • POST /api/v1/auth/reset-password - Reset password

Products

  • GET /api/v1/products - List products with filters
  • POST /api/v1/products - Create product (admin)
  • GET /api/v1/products/:id - Get product details
  • PUT /api/v1/products/:id - Update product (admin)
  • DELETE /api/v1/products/:id - Delete product (admin)
  • POST /api/v1/products/:id/reviews - Add review

Orders

  • POST /api/v1/orders - Create order
  • GET /api/v1/orders - List user orders
  • GET /api/v1/orders/:id - Get order details
  • PUT /api/v1/orders/:id/cancel - Cancel order
  • POST /api/v1/orders/:id/refund - Request refund

Security Best Practices

  1. Never commit the .env file - Use .env.example as a template
  2. Use strong JWT secrets - Generated automatically by quick-start script
  3. Enable HTTPS in production - Use reverse proxy with SSL
  4. Update dependencies regularly - Check for security updates
  5. Monitor rate limits - Adjust based on your needs
  6. Review logs regularly - Check for suspicious activity

Production Deployment

  1. Environment Variables: Set all required variables for production
  2. Database: Use MongoDB Atlas or self-hosted with backups
  3. Redis: Use Redis Cloud or self-hosted with persistence
  4. Process Manager: Use PM2 with cluster mode
  5. Reverse Proxy: Use Nginx or Apache with SSL
  6. Monitoring: Implement APM and error tracking
  7. CI/CD: Automate testing and deployment
