Registering Handlers Generated by oapi-codegen from an OpenAPI Specification

Implement oapi-codegen-generated ServerInterface

oapi-codegen generates a ServerInterface interface that exposes methods to be implemented by the server.

Implement that interface:

type PetStoreServer struct {
  // ...
}

func NewPetStoreServer() *PetStoreServer {
	return &PetStoreServer{}
}

func (s *PetStoreServer) GetPets(ctx echo.Context, params petstore.GetPetsParams) error {
  return nil
}

Register the Handlers

var server = NewPetStoreServer()
e := echo.New()
petstore.RegisterHandlers(e, server)
