FastWSGI

Note: FastWSGI is still under development...

FastWSGI is an ultra fast WSGI server for Python 3.

It is mostly written in C. It makes use of libuv and llhttp under the hood for blazing fast performance.

Installation

Install using the pip package manager.

pip install fastwsgi

Example usage with Flask

See example.py for more details.

import fastwsgi
from flask import Flask

app = Flask(__name__)


@app.get("/")
def hello_world():
    return "Hello, World!", 200


if __name__ == "__main__":
    fastwsgi.run(wsgi_app=app, host="127.0.0.1", port=5000)

Example usage with uWSGI

def application(environ, start_response):
    start_response("200 OK", [("Content-Type", "text/plain")])
    return [b"Hello, World!"]

if __name__ == "__main__":
    fastwsgi.run(wsgi_app=application, host="127.0.0.1", port=5000)

Testing

To run the test suite using pytest, run the following command:

python3 -m pytest

Contributing

Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.

Please make sure to update tests as appropriate.

TODO

• Comprehensive error handling
• Complete HTTP/1.1 compliance
• Test on multiple platforms (Windows/MacOS)
• Unit tests running in CI workflow
• Invoke WSGI app from server.c (from within libuv loop) instead of in request.c (in llhttp parsing callbacks)
