Improve requirements handling (#1287)
* setup: read requirements.txt for dependencies

This makes it easier to keep required packages in sync.

Signed-off-by: Paul Spooren <>

* requirements: Update to click 5.0 and redis 3.5.0

Click 5.0 was already required by the `` and is not brought in
sync. Redis Python library 3.5.0 introduces the `HSET` command with
mapping support which replaces the previous `hmset`. By lifting the
minimal required version to 3.5.0 we can remove the combat function if
Redis server 4.0 is guaranteed.

* ci: remove Python3.4 testing

`redis-py` 3.5.0 does no longer support Python 3.4, so drop it in CI.

RQ (Redis Queue) is a simple Python library for queueing jobs and processing them in the background with workers. It is backed by Redis and it is designed to have a low barrier to entry. It should be integrated in your web stack easily.

RQ requires Redis >= 3.0.0.

Support RQ

If you find RQ useful, please consider supporting this project via Tidelift.

Getting started

First, run a Redis server, of course:

$ redis-server

To put jobs on queues, you don't have to do anything special, just define your typically lengthy or blocking function:

import requests

def count_words_at_url(url):
    """Just an example function that's called async."""
    resp = requests.get(url)
    return len(resp.text.split())

You do use the excellent requests package, don't you?

Then, create an RQ queue:

from redis import Redis
from rq import Queue

q = Queue(connection=Redis())

And enqueue the function call:

from my_module import count_words_at_url
job = q.enqueue(count_words_at_url, '')

For a more complete example, refer to the docs. But this is the essence.

The worker

To start executing enqueued function calls in the background, start a worker from your project's directory:

$ rq worker
*** Listening for work on default
Got count_words_at_url('') from default
Job result = 818
*** Listening for work on default

That's about it.


Simply use the following command to install the latest released version:

pip install rq

If you want the cutting edge version (that may well be broken), use this:

pip install -e git+

Project history

This project has been inspired by the good parts of Celery, Resque and this snippet, and has been created as a lightweight alternative to the heaviness of Celery or other AMQP-based queueing implementations.

You can’t perform that action at this time.
