Making Django REST Framework reactive

Project description

Build Status

This package enables regular Django REST Framework views to become reactive, that is so that client-side applications may get notified of changes to the underlying data as soon as they happen, without the need to poll the API again. While the initial request is done as a regular HTTP request, all the update notifications come through WebSockets.



The reactive extensions for Django REST Framework require the use of Django Channels for push notifications via WebSockets.

From PyPI

pip install djangorestframework-reactive

From source

pip install<git-tree-ish>.tar.gz

where <git-tree-ish> can represent any commit SHA, branch name, tag name, etc. in DRF Reactive’s GitHub repository. For example, to install the latest version from the master branch, use:

pip install


First, add rest_framework_reactive to INSTALLED_APPS.

Configure your Django Channels to include the required paths:

from django.conf.urls import url

from channels.routing import ChannelNameRouter, ProtocolTypeRouter, URLRouter

from rest_framework_reactive.consumers import ClientConsumer, PollObserversConsumer, WorkerConsumer
from rest_framework_reactive.protocol import CHANNEL_POLL_OBSERVER, CHANNEL_WORKER_NOTIFY

application = ProtocolTypeRouter({
    # Client-facing consumers.
    'websocket': URLRouter([
        # To change the prefix, you can import ClientConsumer in your custom
        # Channels routing definitions instead of using these defaults.
        url(r'^ws/(?P<subscriber_id>.+)$', ClientConsumer),

    # Background worker consumers.
    'channel': ChannelNameRouter({
        CHANNEL_POLL_OBSERVER: PollObserversConsumer,
        CHANNEL_WORKER_NOTIFY: WorkerConsumer,

Also, need to be updated to include some additional paths:

urlpatterns = [
  # ...
  url(r'^api/queryobserver/', include('rest_framework_reactive.api_urls')),
  # ...


In addition to running a Django application server instance, you need to also run a separate observer worker process (or multiple of them). You may start it by running:

python runworker rest_framework_reactive.worker rest_framework_reactive.poll_observer
