I've created a PoC to automate GraphQL API creation (code first approach) from protobuf using protobuf extension to define graphql query / mutation name. I'm using protogen <https://pkg.go.dev/google.golang.org/protobuf/compiler/protogen> package to iterate protobuf file definition. Maybe you would like to take a look https://github.com/ncrypthic/graphql-grpc-edge.
