Unicorn
The magical reactive component framework for Django β¨
Unicorn adds modern reactive component functionality to your Django templates without having to learn a new templating language or fight with complicated JavaScript frameworks. It seamlessly extends Django past its server-side framework roots without giving up all of its niceties or forcing you to rebuild your application. With Django Unicorn, you can quickly and easily add rich front-end interactions to your templates, all while using the power of Django.
https://www.django-unicorn.com has extensive documentation, code examples, and more!
β‘ Getting started
1. Install the package
pip install django-unicorn OR poetry add django-unicorn
2. Add django_unicorn to INSTALLED_APPS
# settings.py
INSTALLED_APPS = (
# other apps
"django_unicorn",
)
3. Update urls.py
# urls.py
import django_unicorn
urlpatterns = (
# other urls
path("unicorn/", include("django_unicorn.urls")),
)
4. Add Unicorn to the HTML template
<!-- template.html -->
{% load unicorn %}
<html>
<head>
{% unicorn_scripts %}
</head>
<body>
{% csrf_token %}
</body>
</html>
5. Create a component
python manage.py startunicorn myapp COMPONENT_NAME
Unicorn uses the term "component" to refer to a set of interactive functionality that can be put into templates. A component consists of a Django HTML template and a Python view class which contains the backend code. After running the management command, two new files will be created:
myapp/templates/unicorn/COMPONENT_NAME.html(component template)myapp/components/COMPONENT_NAME.py(component view)
6. Add the component to your template
<!-- template.html -->
{% load unicorn %}
<html>
<head>
{% unicorn_scripts %}
</head>
<body>
{% csrf_token %}
{% unicorn 'COMPONENT_NAME' %}
</body>
</html>
Example todo component
The unicorn: attributes bind the element to data and can also trigger methods by listening for events, e.g. click, input, keydown, etc.
<!-- todo.html -->
<div>
<form unicorn:submit.prevent="add">
<input type="text"
unicorn:model.defer="task"
unicorn:keyup.escape="task=''"
placeholder="New task" id="task"></input>
</form>
<button unicorn:click="add">Add</button>
<button unicorn:click="$reset">Clear all tasks</button>
<p>
{% if tasks %}
<ul>
{% for task in tasks %}
<li>{{ task }}</li>
{% endfor %}
</ul>
{% else %}
No tasks π
{% endif %}
</p>
</div>
# todo.py
from django_unicorn.components import UnicornView
from django import forms
class TodoForm(forms.Form):
task = forms.CharField(min_length=2, max_length=20, required=True)
class TodoView(UnicornView):
task = ""
tasks = []
def add(self):
if self.is_valid():
self.tasks.append(self.task)
self.task = ""
β¨ Wait, is this magic?
Sort of! At least it might feel like it. π€©
Unicornprogressively enhances a normal Django view, so the initial render is fast and great for SEO.Unicornbinds to the elements you specify and automatically makes AJAX calls when needed.Unicornseamlessly updates the DOM when the HTML changes.
Focus on building regular Django templates and Python classes without needing to switch to another language or use unnecessary infrastructure.
π€― But wait, there's more!
As if that wasn't enough, other features include:
- Form Validation
- Redirection
- Loading States
- Dirty States
- Partial Updates
- Polling
- Scroll Triggering
- Messages
- Javascript Integration
