Backend Travel API

This project is a backend API for a travel-related application, built with Go. It provides endpoints and services for managing airports, flights, locations, notifications, authentication, and more. The architecture follows a modular structure with clear separation of concerns.

Features

• User authentication and authorization (JWT-based)
• Airport, flight, and location management
• Real-time notifications via WebSocket and FCM
• Integration with external aviation APIs
• Redis caching
• RESTful API design
• Middleware for CORS and authentication
