Thank you for confirming that the environment variables have been added to your Vercel project. These variables will be used by the Flight and Hotel services to connect to their respective external APIs.

Using the Environment Variables

The API is now configured to use these environment variables in the following services:

1. Flight Service (src/services/flight.service.ts):

   • FLIGHT_API_URL - The base URL for the flight search API
   • FLIGHT_API_KEY - The authentication key for the flight API

2. Hotel Service (src/services/hotel.service.ts):

   • HOTEL_API_URL - The base URL for the hotel search API
   • HOTEL_API_KEY - The authentication key for the hotel API

Testing the API Endpoints

Now that the environment variables are set up, you can test the flight and hotel search endpoints:

Flight Search

Hotel Search

Next Steps

1. Database Setup: Make sure your PostgreSQL database is properly set up and the connection string is configured in your environment variables.

2. Run Migrations: Execute the Prisma migrations to create your database schema:

   bun run db:migrate

3. Seed the Database: Populate your database with initial data:

   bun run db:seed

4. Start the Server: Run the development server:

   bun run dev
5. API Documentation: Consider adding API documentation using tools like Swagger/OpenAPI to make it easier for frontend developers to understand and use your API.

The implementation is now complete with all the required modules and endpoints. The API is structured in a modular way, making it easy to maintain and extend in the future. If you need any specific adjustments or have questions about any part of the implementation, please let me know!

Professional Travel API Enhancements

I'll enhance the API to make it more professional and production-ready, focusing on features that top travel APIs typically implement.

Professional Travel API Enhancements Summary

I've significantly enhanced the Travel API to make it more professional and production-ready, focusing on features that top travel APIs typically implement. Here's a summary of the improvements:

1. Security Enhancements

• Rate limiting with Redis support to prevent abuse
• Enhanced security headers to protect against common web vulnerabilities
• Improved error handling with detailed error codes and messages
• More robust authentication with refresh tokens

2. Performance Optimizations

• Redis-based caching system for frequently accessed data
• Caching middleware for API responses
• Performance monitoring to track response times

3. Advanced Features

• Internationalization support for multiple languages
• Enhanced search capabilities with filtering, sorting, and autocomplete
• Webhook system for real-time event notifications
• Improved payment processing with idempotency and refund support

4. Developer Experience

• Swagger API documentation for easier API exploration
• Comprehensive error handling with detailed error messages
• Monitoring and analytics for tracking API usage

5. DevOps & Deployment

• Docker support for containerization
• CI/CD pipeline with GitHub Actions
• Environment configuration for different deployment environments

6. Code Quality

• Linting and formatting with ESLint and Prettier
• Type safety with TypeScript
• Automated testing setup

These enhancements make the API more:

• Scalable - with caching and performance optimizations
• Secure - with proper authentication and security headers
• Maintainable - with better error handling and documentation
• User-friendly - with internationalization and better search
• Developer-friendly - with comprehensive documentation and tooling

The API now follows industry best practices and is ready for production use in a professional travel application.
