asgitools

A collection of tools for developing ASGI applications. Supports both ASGI servers, uvicorn and daphne.

Requirements: Python 3.5.3+ and an ASGI server

Currently includes:

• Protocol and URL routing
• WSGI debug middleware
• Redis broadcast middleware

Quickstart

You can find an example app in examples/ that demonstrates protocol, url routing, middleware usage, and wsgi debugger.

Otherwise you can try the example below to run a simple HTTP app:

Install using pip:

Create an application, in app.py:

from asgitools.routing import (
    AsgiProtocolRouter,
    AsgiProtocol,
    AsgiUrlRouter,
    AsgiUrlRoute
)


class HttpConsumer:

    def __init__(self, scope):
        self.scope = scope

    async def __call__(self, receive, send):
        message = await receive()
        if message['type'] == 'http.request':
            await send({
                'type': 'http.response.start',
                'status': 200,
                'headers': [
                    [b'content-type', b'text/html'],
                ],
            })
            await send({
                'type': 'http.response.body',
                'body': b'Hello world!',
                'more_body': False,
            })


app = AsgiProtocolRouter([
    AsgiProtocol(
        'http',
        AsgiUrlRouter([
            AsgiUrlRoute(
                '/', HttpConsumer, methods=['GET']
            ),
        ])
    ),
])

Run the server:

$ uvicorn app:app

OR

$ daphne app:app
