gRPC Zero to Hero

• Tech Stack: Python 3.12+, grpcio (grpc.aio), Protocol Buffers, pytest, Docker, uv
• Github URL: Project Link

A single, comprehensive Python codebase that doubles as an educational reference and a production-ready template for gRPC. It demonstrates all four RPC patterns — unary, server streaming, client streaming and bidirectional — alongside Proto3 features like nested messages, enums, oneofs, maps and versioning.

It goes deep on the operational side too: client and server interceptors (logging, auth, retries, metrics), TLS / mutual-TLS and bearer-token auth, DNS-based round-robin load balancing, health checking, server reflection, channelz introspection and graceful shutdown — all backed by an in-process test suite and load-testing utilities.
