What it is and what it does
Twirp is a Python RPC framework that lets you define services in protobuf and automatically generate both server and client code. It implements the Twirp Wire Protocol v7, which is a lightweight alternative to gRPC that works over HTTP. The package provides an ASGI-compatible server wrapper (TwirpASGIApp) that you can run with uvicorn, plus client stubs that speak the Twirp protocol to remote services.
You define your service interface in a .proto file, run the protoc compiler with the twirpy plugin to generate Python code, then implement your service logic by subclassing the generated server class. The framework handles serialization, HTTP routing, and error handling. It depends on requests for HTTP calls, structlog for logging, and protobuf for message encoding.
Use it for
- Build microservices that communicate via Twirp RPC instead of REST or gRPC.
- Generate type-safe client and server stubs from protobuf definitions with minimal boilerplate.
- Migrate from Twirp services in other languages to Python.
- Create lightweight RPC services that run on standard ASGI servers like uvicorn.
