Flight API

A Go-based HTTP API for searching flights, authentication, health checks, and OpenAPI/Swagger documentation. Built with Fiber, Wire for DI, Go‑Playground/Validator for validation, JWT for auth, and Redis for rate‑limiting.

Features

• Health check endpoint (GET /api/health)
• User login with email/password (POST /api/v1/auth/login)
• JWT‑based authentication middleware for protected routes
• Flight search endpoint (GET /api/v1/flights/search)
• OpenAPI/Swagger docs served under /api/docs
• Docker support & Makefile commands
• Unit & integration tests with testify, Fiber’s test harness, Dockerized Redis
