Support Dramatiq via Tidelift

If you want to use it with RabbitMQ

pipenv install 'dramatiq[rabbitmq, watch]'

or if you want to use it with Redis

pipenv install 'dramatiq[redis, watch]'

If you use and love Dramatiq and want to make sure it gets the love and attention it deserves then you should consider supporting the project. There are three ways in which you can do this right now:

1. If you're a company that uses Dramatiq in production then you can get a Tidelift subscription. Doing so will give you an easy route to supporting both Dramatiq and other open source projects that you depend on.
2. If you're an individual or a company that doesn't want to go through Tidelift then you can support the project via Patreon.
3. If you're a company and neither option works for you and you would like to receive an invoice from me directly then email me at [email protected] and let's talk.

Make sure you've got RabbitMQ running, then create a new file called example.py:

import dramatiq
import requests
import sys

@dramatiq.actor
def count_words(url):
    response = requests.get(url)
    count = len(response.text.split(" "))
    print(f"There are {count} words at {url!r}.")


if __name__ == "__main__":
    count_words.send(sys.argv[1])

In one terminal, run your workers:

In another, start enqueueing messages:

python example.py http://example.com
python example.py https://github.com
python example.py https://news.ycombinator.com
