Do you use swagger to generate backends?

• GoSwagger

  25 9,271 8.8 Go

  Swagger 2.0 implementation for go

  

Then define the corresponding YAML/JSON specification (again manually) either using Swagger 2.0 (with go-swagger) or OpenAPI 3 (with kin-openapi), and

• openapi-generator

  234 19,807 9.9 Java

  OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (v2, v3)

  

I had a play with this approach a couple of months ago. The goal was to come up with a workflow built around the https://openapi-generator.tech (https://github.com/OpenAPITools/openapi-generator) OpenAPI code generator which would enable a swagger/OpenAPI spec doc to be iterated upon and for changes to the spec doc to result in automated updates to generated GO server code.

• kin-openapi

  6 2,372 8.4 Go

  OpenAPI 3.0 (and Swagger v2) implementation for Go (parsing, converting, validation, and more)

  

Then define the corresponding YAML/JSON specification (again manually) either using Swagger 2.0 (with go-swagger) or OpenAPI 3 (with kin-openapi), and

• oapi-codegen

  64 5,178 9.1 Go

  Generate Go client and server boilerplate from OpenAPI 3 specifications

  

Finally, if you need to generate clients, use the corresponding generate -like tools, go-swagger uses swagger generate, and for OpenAPI 3 you could use oapi-codegen.

• go-user-api

  1 1 3.5 Go

  A sample Go user API

I ended up with https://github.com/jjssoftware/go-user-api which uses an automated github workflow and it did work.

• swagger-petstore

  28 16,527 8.5 Mustache

  swagger-codegen contains a template-driven engine to generate documentation, API clients and server stubs in different languages by parsing your OpenAPI / Swagger definition.

  

Not specific to Go, but included, there are two main code generators: Swagger codegen (the private company project) and OpenAPI codegen (the opensource, community driven project)

  11 311 6.6 Go

  Web services with OpenAPI and JSON Schema done quick in Go (by swaggest)

  

I've tried go-swagger comments to instrument existing code, but wasn't quite satisfied due to magical nature and error friendliness of those comments. So I decided to implement first-class OpenAPI generation on top of self-documenting action handlers: https://github.com/swaggest/rest/blob/master/_examples/basic/main.go. Schemas are generated from request and response structures using reflection and field tags.
