Api Gateway Configuration

This covers the essentials for setting up API gateways across Kong, Nginx, AWS API Gateway, Traefik, and even a custom Node.js implementation. You get reference configs for routing, JWT authentication, rate limiting, CORS, and request transformation. The best practices section is solid on the basics like centralizing auth, implementing circuit breakers, and not exposing backend details. It's a decent starting point if you're wiring up microservices or need a reverse proxy with traffic management, though you'll still need to adapt these examples to your specific infrastructure and security requirements. The Kong and Nginx configs are probably the most immediately useful.
