Building APIs
summary
Explains how to build production-ready web APIs using the standard library around http.HandlerFunc and the ResponseWriter/Request pair, favors JSON-only endpoints, and shows concrete tooling: routing with Gorilla M (path params and method-specific handlers), per-request DB session handling with mgo stored in request context, a reusable respond/decode/OK-validation pattern, composable middleware via adapter functions, and testing with the Testify style plus net/http/httptest server and table-driven tests.
