echo_proto

README

1. Define your .proto file

Create echo.proto:

syntax = "proto3";

package pb;
option go_package = "./pb";

service EchoService {
    rpc Echo(EchoRequest) returns (EchoResponse);
}

message EchoRequest {
    string message = 1;
}

message EchoResponse {
    string message = 1;
}

---

2. Generate Go code

Run the following command to generate both Protobuf types and aRPC stubs:

protoc \
  --go_out=paths=source_relative:. \
  --arpc_out=paths=source_relative:. \
  proto/echo.proto

This will generate:

• Standard Go types from Protobuf definitions (via protoc-gen-go)
• aRPC client/server stubs (via protoc-gen-arpc) in *_arpc.pb.go

---

3. Run the client and server

Start the server:

go run server/server.go

In a separate terminal, run the client:

go run frontend/frontend.go

4. Test

curl http://localhost:8080?key=hello
