Granian

A Rust HTTP server for Python applications.

Rationale

The main reasons behind Granian design are:

  • Have a single, correct HTTP implementation, supporting versions 1, 2 (and eventually 3)
  • Provide a single package for several platforms
  • Avoid the usual Gunicorn + uvicorn + http-tools dependency composition on unix systems
  • Provide stable performance when compared to existing alternatives

Features

  • Supports ASGI/3, RSGI and WSGI interface applications
  • Implements HTTP/1 and HTTP/2 protocols
  • Supports HTTPS
  • Supports Websockets over HTTP/1 and HTTP/2

Quickstart

You can install Granian using pip:

$ pip install granian

Create an ASGI application in your main.py:

async def app(scope, receive, send):
    assert scope['type'] == 'http'

    await send({
        'type': 'http.response.start',
        'status': 200,
        'headers': [
            [b'content-type', b'text/plain'],
        ],
    })
    await send({
        'type': 'http.response.body',
        'body': b'Hello, world!',
    })

and serve it:

$ granian --interface asgi main:app

You can also create an app using the RSGI specification:

async def app(scope, proto):
    assert scope.proto == 'http'

    proto.response_str(
        status=200,
        headers=[
            ('content-type', 'text/plain')
        ],
        body="Hello, world!"
    )

and serve it using:

$ granian --interface rsgi main:app

Project status
