Compact gRPC server and client implementation (Go & Python)

To build and run

Using docker compose:

docker-compose up --build

Prerequisites

1. protoc for Windows, protobuf-compiler for Linux.
2. grpcio-tools, grpclib, protobuf (python packages).
3. https://github.com/nipunn1313/mypy-protobuf (pip install mypy-protobuf)

Generate proto files

Run makefile:

make

Export requirements.txt

Run uv export:

cd python
uv export --no-dev --output-file requirements.txt

Notes & Todos

• For newly proto generated python files, inside _pb2_grpc.py files, fix first import with absolute package path.
• No need to manage proto generated python files, as they are generated in the project directory, even though it would be a good idea to publish and use it as third party package.
• Would be nice to add multi-stage docker build.
• Would be nice to use uv for python docker build.
• Would be nice to add a proper di in python app.
• Would be nice to correctly set mypy to ignore proto generated python files to allow the use of --strict flag.
• Would be nice to use proper configuration techniques for both apps for different environments.

Even though it is just a short demo of how adequately use go grpc server and python grpc client.
