twirpy 0.3.0.dev2

Twirp runtime library for Python

Twirpy

Twirp is a framework for service-to-service communication emphasizing simplicity and minimalism. It generates routing and serialization from API definition files and lets you focus on your application's logic instead of thinking about folderol like HTTP methods and paths and JSON.

-- Twirp's README

Twirpy is a Python implementation of the Twirp framework. It currently supports Twirp Wire Protocol v7.

This repository contains:

• a protoc (aka the Protocol Compiler) plugin that generates sever and client code;
• a Python package with common implementation details.

Installation

Runtime Library

The runtime library package contains common types like TwirpServer and TwirpClient that are used by the generated code.

Add the Twirp package to your Python project with:

pip install twirpy

Code Generator

You need to install protoc, the Protocol Buffers compiler, and the protoc-gen-twirpy protoc plugin to generate code.

First, install the Protocol Buffers compiler. For installation instructions, see Protocol Buffer Compiler Installation documentation. You can also use your package manager (e.g. brew install protobuf on macOS).

Go the releases page, and download the protoc-gen-twirpy binary for your platform. Unzip the archive and move the binary to a directory in your PATH.

On macOS, you can use the following commands:

curl -L -o- \
  https://github.com/Cryptact/twirpy/releases/latest/download/protoc-gen-twirpy-darwin-arm64.tar.gz \
  | tar xz -C ~/.local/bin protoc-gen-twirpy

Generate and run

Use the protoc plugin to generate twirp server and client code.

protoc --python_out=. --pyi_out=. --twirpy_out=. example/rpc/haberdasher/service.proto

For more information on how to generate code, see the example.

Development

We use hatch to manage the development process.

To open a shell with the development environment, run: hatch shell. To run the linter, run: hatch fmt --check or hatch fmt to fix the issues.

To run the type checker, run: hatch run types:check.

Standing on the shoulders of giants

• The initial version of twirpy was made from an internal copy of https://github.com/daroot/protoc-gen-twirp_python_srv
• The work done by Verloop on the initial versions of Twirpy.
• The run_in_threadpool method comes from https://github.com/encode/starlette
