How Senior Engineers Design Production APIs
Content is AI-assisted and may contain inaccuracies.
A new video walks through building a production-grade API from scratch, focused on what separates a working API from one ready for production. Topics include clean route design, endpoint naming rules, the five common HTTP methods, contract-first development, DTOs with input and output validation, OpenAPI spec generation, consistent error handling, authentication versus authorization, and rate limiting via middleware.
The build uses oRPC to keep the contract, implementation, typed client, and documentation synchronized, with an advanced endpoint demonstrated alongside the base project setup. The premise: as AI coding agents make code generation faster and cheaper, rigorous API design matters more, not less.
