Auto-Generate OpenAPI and Swagger UI in Go with Rivaas
Keeping an OpenAPI file up to date by hand is slow and easy to get wrong. Your code changes, but the spec does not, and clients stop trusting the docs. Rivaas helps by building the OpenAPI document when your app runs. You describe each route next to the handler, and your Go types become JSON Schema in the spec. This tutorial shows a small working API and where to open Swagger UI.
