I see your problem (which is btw quite different from your original comment ;-) ). In a statically-typed language like Reason it's difficult to model dynamically-generated types like `hello_proto.Greeter`. One way is to use a functor ( https://v1.realworldocaml.org/v1/en/html/functors.html https://v1.realworldocaml.org/v1/en/html/functors.html ) but they have their limitations. This is why we have things like graphql_ppx which is a compiler extension to generate types from GraphQL schemas at compile-time. You'd need something like this (or, easier, a ReasonML-targeting gRPC/Protobuf client generator) to solve the issue brought up in GitHub.
