With tools like ogen[1], one can take a single Swagger or OpenAPI doc and generate server code with request/response validation, Prometheus metrics, OpenTelemetry, and more.
It can also generate clients and webhooks. Authentication is just declaring a SecurityScheme in the OpenAPI documentation then implementing a single function. The rest of the backend is just implementing a single interface. Unlike oapi-codegen, there is no need to tinker with middleware for authentication or logging.
Pair this with a tool like sqlc[2] and SQLite's `pragma user_version`, and you get type-safe database code and database migrations for free. I will concede that adding SQLite is a manual process, but its just two imports added to main.go.
Frontend is entirely your choice. Go's standard library provides good enough text templating that I don't miss ERB or Django-style templates. Using embed/fs, one can easily embed a bunch of assets into a single static binary, so deployment can be as simple as `go build` and moving a single binary.
I actually have a hard time using languages besides Go for developing backends, because the code generation tools eliminate the boilerplate I frequently face in other languages while also avoiding the hundreds of dependencies that Spring Boot or Quarkus need.
