Guessing game with gRPC

This example provides a simple version of the guessing game example using gRPC. At present, it only supports sending guesses--no other features from later lectures are supported.

Relevant files

• proto/guessing-game.proto: gRPC/protobuf specification for the messages
• cmd/server/main.go: Guessing game server (Golang)
• client/client.py: Guessing game client (Python)
• pkg/proto/*: protobuf-generated RPC code (Server)
• client/*_pb2.py: protobuf-generated RPC code (Client)

Setup

You can compile the server using make. To run the client, you will need a Python environment with gRPC--to set this up, you can create a virtual environment using the provided requirements.txt.

If you want to change the protobuf spec, you need to recompile the generated code. To do this, you need protobuf and gRPC installed for each language for which you intend to generate code (in this case, golang and Python). For details on how to do this yourself, see gRPC's setup docs:
