Building Robust APIs
APIs are the contract between systems. Whether you are exposing a public REST endpoint, designing an internal GraphQL schema, or integrating with a third-party service, the patterns you choose determine reliability, performance, and developer experience.
Here you will find recipes for handling CORS, implementing pagination, versioning endpoints, managing rate limits, and documenting APIs with OpenAPI. Each example includes runnable code in multiple languages so you can adapt it to your stack immediately.
