Django Single File Templates -- inspired by Vue's Single file components
Make your Django templates more organized by holding your HTML and all the related CSS and JavaScript in a sensible way.

Disclaimer: This package serves as a proof of concept rather than a production-ready solution!
Motivation
From Vue's documentation:
One important thing to note is that separation of concerns is not equal to separation of file types. In modern UI development, we have found that instead of dividing the codebase into three huge layers that interweave with one another, it makes much more sense to divide them into loosely-coupled components and compose them. Inside a component, its template, logic and styles are inherently coupled, and collocating them actually makes the component more cohesive and maintainable.
Similar logic could be applied to Django's templates. HTML, JavaScript and CSS are inherently coupled so it makes sense to put them together.
Introducing Django Single File Templates (SFT).
Quickstart
Install Django Single File Templates:
pip install django-sft
Add it to your INSTALLED_APPS:
INSTALLED_APPS = (
...
'django_sft',
...
)
Add SFT Template loader (in your settings.py):
TEMPLATES = [
{
...
'OPTIONS': {
'loaders': [
'django_sft.template.SFTLoader',
'django.template.loaders.filesystem.Loader',
'django.template.loaders.app_directories.Loader',
],
...
}
}
]
You can now start using Single file templates as your templates.
Usage
Add a new SFT by adding a .sft file to your templates folder (either
in your apps or root templates folder). SFT should include at least HTML
(you can use Django's template language), but it can also include
script and style tags:
<template>
{% load static %}
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Example Website</title>
</head>
<body>
<header>
<nav>
<a href="/">Home</a>
<a href="/page" id="page">Page</a>
</nav>
</header>
{% block main %}
<h1>This is where the content will go</h1>
{% endblock %}
</body>
</html>
</template>
<script>
const page = document.getElementById('page');
page.addEventListener('click', (ev) => {
ev.preventDefault();
alert('You clicked the page');
});
</script>
<style>
body {
background-color: gray;
}
</style>
In your views you can render this template directly and SFT Template loader will get the right template for you.
def view(request):
return render('my-template.sft')
Single file templates can also extend other STFs.
<template>
{% extends 'example/base.sft' %}}
{% block main %}
<h1>This is index page</h1>
<h2>Update</h2>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Fugit eaque obcaecati maxime eos inventore tenetur, debitis atque quaerat modi, et illum id error quisquam consequatur reprehenderit, laboriosam exercitationem, provident aut.</p>
<h2 id="time"></h2>
{% endblock %}
</template>
<script>
document.getElementById('time').innerHTML = new Date();
</script>
<style>
p {
width: 50%;
background-color: white;
margin: auto;
}
</style>
It can also include external scripts and styles (bootstrap example):
<template>
...
</template>
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.bundle.min.js"></script>
<script>
const page = document.getElementById('page');
page.addEventListener('click', (ev) => {
ev.preventDefault();
alert('You clicked the page');
});
</script>
<style src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css"></style>
<style>
body {
background-color: gray;
}
</style>
Single file templates will automatically be parsed and compiled when you
manage.py runserver if DEBUG = True. You can also run
manage.py compile_sft to compile manually.
How does it work?
When SFT is compiled (on runserver or manually), django-sft will grab
the SFT file and produce appropriate .js, .css and .html files.
They will be created in sft directory (under static and templates
directories respectively). The html files will be automatically injected
with references to the static files. When a view will try to render
.sft template, the SFT Template Loader will look for resulting .html
file instead and return that.
The current implementation is quite simple and serves as a proof of concept rather than a production-ready solution.
Look for a working example under tests folder.
