Asynchronous coroutines worker

Crate

Crate is a lightweight Python (3.5) coroutine worker (à la Celery) to allow asynchronous tasks into your application.

Getting started

Create your my_crate.py into your project:

import asyncio
from datetime import datetime

from crate import Crate

app = Crate()


@app.task
async def hello_world(waiting: int=2) -> None:
    print('[{}] Hello world!'.format(datetime.now()))
    await asyncio.sleep(waiting)
    print('[{}] Wumba lumba dub dub...'.format(datetime.now()))

And run your worker:

crate --app my_crate:app

You can call tasks in two different ways:

# If you have access to task code

from my_crate import hello_world

hello_world.delay()

# Or just task name

from crate import Crate

app = Crate()
app.send_task('hello_world')
