Asgineer

A really thin ASGI web framework 🐍🤘

Introduction

Asgineer is a tool to write asynchronous web applications, using as few abstractions as possible, while still offering a friendly API. The guide and reference take just a few minutes to read!

When running Asgineer on Uvicorn, it is one of the fastest web frameworks available. It supports http long polling, server side events (SSE), and websockets. And has utilities to serve assets the right (and fast) way.

Asgineer is proudly used to serve e.g. https://pyzo.org and https://timetagger.app.

Example

# example.py

import asgineer

@asgineer.to_asgi
async def main(request):
    return f"<html>You requested <b>{request.path}</b></html>"

if __name__ == '__main__':
    asgineer.run(main, 'uvicorn', 'localhost:8080')

You can start the server by running this script, or start it the ASGI way, e.g. with Uvicorn:

$ uvicorn example:main --host=localhost --port=8080

Installation and dependencies

Asgineer needs Python 3.8 or higher (may work on older versions but is not tested). To install or upgrade, run:

$ pip install -U asgineer

Asgineer has zero hard dependencies, but it needs an ASGI server to run on, like Uvicorn, Hypercorn, or Daphne.

Development

Install with pip install -e .[dev].

• ruff format to apply code formatting.
• ruff check to test for unused imports and more.
• pytest tests to run the tests, optionally set the ASGI_SERVER environment variable.
