Q49: How can Express be used as an API Gateway in a Microservices Architecture?
An Express API Gateway handles client entry points, centralizes authentication checks, applies rate limiting, and proxies requests downstream to internal microservices using express-http-proxy or http-proxy-middleware.
Key Takeaways
- Centralizes authentication, rate limiting, and request logging in one proxy layer.
- Proxies incoming client traffic seamlessly to downstream microservices.
