DynagRPC

DynagRPC is a Python library to help writing/using gRPC and protobuf.

Simple server implementation

Say we have this protobuf definition for a simple addition RPC:

syntax = "proto3";
package tests.maths;

service Maths {
  rpc Add (AddRequest) returns (AddResponse) {}
}

message AddRequest {
  int32 first = 1;
  int32 second = 2;
}

message AddResponse {
  int32 result = 1;
}

Keeping just the proto (i.e., not compiled with protoc), we can use it with the following implementation in Python is:

from dynagrpc import GrpcServer

server = GrpcServer("tests", "Maths", "maths")

@server.rpc()
def add(first, second):
    return first + second

Which you can run, for example, with:

server.run(host="localhost", port="50051")
