twirp-swagger-gen

A Twirp RPC Swagger/OpenAPI 2.0 generator

Usage

Installing the generator for protoc/buf:

go get -u github.com/candy-digital/twirp-swagger-gen

This should pull in the cmd/ folder as well. Installing just the binaries:

go install github.com/candy-digital/twirp-swagger-gen/cmd/...

Running the standalone version:

twirp-swagger-gen \
	-in example/example.proto \
	-out example/example.swagger.json \
	-host test.example.com

Running the protoc code with buf.build (buf.gen.yaml):

version: v1
plugins:
  - name: twirp-swagger
    opt: hostname=api.example.com,path_prefix=/api/v1
    out: example/buf

Other? Try to figure it out, then open a PR for the README.

Why?

The project elliots/protoc-gen-twirp_swagger is defunct due to upstream changes to grpc-ecosystem dependencies.

This project is a rewrite, that relies on both the official OpenAPI structures, and a generic .proto file parser. The output should be line compatible - my goal was just to replace the generator with a working one without still being exposed to breaking changes from the gRPC ecosystem packages.

The generated output is suitable for Swagger-UI.
