RPCProtoGenHelpers

This library defines a buf custom plugin.

This plugin reads in a bunch of proto files, and for the RPC services generates some helpers: behaviour modules and "impl" modules to make calling and testing gRPC methods easier.

This repo is not intended to be used directly, but rather includes an escript. This can be used as part of a shell script:

which protoc-gen-elixir-rpc || PATH="~/.mix/escripts:$PATH" && mix escript.install --force github surgeventures/elixir-rpc-proto-gen-helpers

Then you can use the plugin for buf generate. An example buf config file might be:

version: v1
plugins:
  - name: elixir
    strategy: all
    out: ./lib/generated
    opt: plugins=grpc
  - name: elixir-rpc
    strategy: all
    out: ./lib/generated
    opt: plugins=grpc
