Unmaintained // Turbo for Django

Warning

This library is unmaintained. Integrating Hotwire and Django is so easy that you are probably better served by writing a little bit of Python in your code than using a full-blown library that adds another level of abstraction. It also seems that the Django community is leaning more towards HTMX than Hotwire so you might want to look over there if you want more "support" (but we still think that Hotwire is very well suited to be used with Django)

Integrate Hotwire Turbo with Django with ease.

Requirements

  • Python 3.8+
  • Django 3.1+
  • Channels 3.0+ (Optional for Turbo Frames, but needed for Turbo Stream support)

Installation

Turbo Django is available on PyPI - to install it, just run:

pip install turbo-django

Add turbo and channels to INSTALLED_APPS, and copy the following CHANNEL_LAYERS setting:

INSTALLED_APPS = [
    ...
    'turbo',
    'channels'
    ...
]

CHANNEL_LAYERS = {
    "default": {
        # You will need to `pip install channels_redis` and configure a redis instance.
        # Using InMemoryChannelLayer will not work as the memory is not shared between threads.
        # See https://channels.readthedocs.io/en/latest/topics/channel_layers.html
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("127.0.0.1", 6379)],
        },
    }
}

And collect static files if the development server is not hosting them:

./manage.py collectstatic

Note: Both Hotwire and this library are still in beta development and may introduce breaking API changes between releases. It is advised to pin the library to a specific version during install.

Quickstart

Want to see Hotwire in action? Here's a simple broadcast that can be setup in less than a minute.

The basics:

  • A Turbo Stream class is declared in python.

  • A template subscribes to the Turbo Stream.

  • HTML is be pushed to all subscribed pages which replaces the content of specified HTML p tag.

Example

First, in a django app called quickstart, declare BroadcastStream in a file named streams.py.

# streams.py

import turbo

class BroadcastStream(turbo.Stream):
    pass

Then, create a template that subscribes to the stream.

from django.urls import path
from django.views.generic import TemplateView

urlpatterns = [
    path('quickstart/', TemplateView.as_view(template_name='broadcast_example.html'))
]
# broadcast_example.html

{% load turbo_streams %}
<!DOCTYPE html>
<html lang="en">
<head>
    {% include "turbo/head.html" %}
</head>
<body>
    {% turbo_subscribe 'quickstart:BroadcastStream' %}

    <p id="broadcast_box">Placeholder for broadcast</p>
</body>
</html>

Now run ./manage.py shell. Import the Turbo Stream and tell the stream to take the current timestamp and update the element with id broadcast_box on all subscribed pages.

from quickstart.streams import BroadcastStream
from datetime import datetime

BroadcastStream().update(text=f"The date and time is now: {datetime.now()}", id="broadcast_box")

With the quickstart/ path open in a browser window, watch as the broadcast pushes messages to the page.

Now change .update() to .append() and resend the broadcast a few times. Notice you do not have to reload the page to get this modified behavior.
