gRPC example

Usage

I've implemented some docker-compose file to make easy run tests. All docker-compose files have all clients written in NodeJS, Python, Ruby and Elixir.

To run the gRPC server in a specific language, choose between the docker-compose files:

1. docker-compose-nodejs-server.yaml - gRPC server implemented in NodeJS language
2. docker-compose-python-server.yaml - gRPC server implemented in Python language
3. docker-compose-ruby-server.yaml - gRPC server implemented in Ruby language
4. docker-compose-elixir-server.yaml - gRPC server implemented in Elixir language

To run the gRPC server use:

$ docker-compose -f ${docker-compose-file} up server

To run the grPC client use:

$ docker-compose -f ${docker-compose-file} up ${client}

${docker-compose-file} must be docker-compose-nodejs-server.yaml, docker-compose-python-server.yaml, docker-compose-ruby-server.yaml or docker-compose-elixir-server.yaml.

${client} must be nodejs, python, ruby or elixir.

Protocol Buffer

Simple protobuf definition in protobufs/greeter.proto.

gRPC NodeJS Server

Server implementation of protobufs/greeter.proto in nodejs/server.js.

gRPC Clients

NodeJS Client

Client implementation in nodejs/client.js.

Python Client

To generate the Python stub methods I've installed pip install grpcio grpcio-tools and ran python python/generate_pb.py. See python client implementation in python/client.py.

Ruby Client

To generate the Ruby stub methods I've installed gem install grpc grpc-tools and ran grpc_tools_ruby_protoc -I ../protobufs --ruby_out=. --grpc_out=. ../protobufs/greeter.proto. See ruby client implementation in ruby/client.rb.

Elixir Client

Client implementation in elixir/priv/client.exs.
