Using go server generator

Go server generator is used to generate HTTP router and models along with initial controller and service based on OpenAPI spec. So it’s just a matter of setting up the right service and wiring them to the router.

The openapi directory looks like:

├── openapi
│   ├── components
│   │   └── schemas.yaml
│   ├── config
│   │   └── go-server.yaml
│   ├── openapi.yaml
│   └── paths
│       └── journals.yaml

The configuration specifies the generator name, go-server, the source of specification, the output directory for the generated code, and the package name of the generated Go files.

go-server.yaml

generatorName: go-server
inputSpec: openapi/openapi.yaml
outputDir: server/gen
additionalProperties:
  packageName: gen
  enumClassPrefix: true

To run the generator: openapi-generator-cli generate -c openapi/config/go-server.yaml
