Usage

The following trival example uses the uvicorn server. See here for more.

import uvicorn
import json
from bareasgi import Application, text_reader, text_writer

async def get_info(scope, info, matches, content):
    text = json.dumps(info)
    return 200, [(b'content-type', b'application/json')], text_writer(text)

async def set_info(scope, info, matches, content):
    text = await text_reader(content)
    data = json.loads(text)
    info.update(data)
    return 204

app = Application(info={'name': 'Michael Caine'})
app.http_router.add({'GET'}, '/info', get_info)
app.http_router.add({'POST'}, '/info', set_info)

uvicorn.run(app, port=9009)

The above example demonstrates some of the key features of this implementation.

• All the handler arguments are simple Python objects (list, dict, tuple, etc).
• Arguments like scope are passed directly from the ASGI server without being processed into helper classes.
• All features (even JSON encoding) are the responsibility of the application, not the framework.
• Handlers are asynchronous. The text_writer function is a simple wrapper which turns text into an async byte stream.
