1. Introduction
Replace JavaScript in your Django apps with... HTMX?
Discover how HTMX transforms Django apps by replacing complex JavaScript with simple HTML attributes. Faster, cleaner, and more maintainable.
Yes...HTMX lets you add AJAX, partial updates, and dynamic UX with simple HTML attributes. In this article, we’ll explore how HTMX works, how to integrate it with Django, and why it’s a game-changer. By the end, you’ll be able to build reactive Django apps without writing a single line of JavaScript all with the help of HTMX.
2. What is HTMX?
-
Lightweight JavaScript library that lets you make HTTP requests directly from HTML.
-
Supports GET, POST, PUT, and DELETE through attributes like hx-get, hx-post, etc.
-
Encourages HTML over the wire. server sends rendered HTML fragments, not raw JSON.
<button hx-post="/like/42/" hx-swap="outerHTML">Like</button>
3. Why replace javascript with HTMX?
| Traditional JS |
HTMX |
| JS logic + API |
HTML attributes |
| Handle JSON |
Return HTML |
| DOM manually updated |
Automatic swap via hx-target, hx-swap |

4. Integrating HTMX into Django
a. Install HTMX
Add to your base template:
<script src="https://unpkg.com/htmx.org@1.9.2"></script>
b. Create Django View
from django.shortcuts import render
def increment_counter(request):
count = int(request.GET.get('count', 0)) + 1
return render(request, 'partials/counter.html', {'count': count})
c. Add partials template
<!-- templates/partials/counter.html -->
<button hx-get="/increment/?count={{ count }}" hx-target="#counter" hx-swap="outerHTML">
Count: {{ count }}
</button>
d. Hook It Up in Main Page
<div id="counter">
{% include 'partials/counter.html' with count=0 %}
</div>
5. Security and Best Practices
-
CSRF: Django templates auto-include CSRF tokens, just add hx-headers='{"X-CSRFToken": "{{ csrf_token }}"}'
-
Use hx-boost="true" for progressive enhancement (links/forms become AJAX)
-
Structure your Django app with partial templates (partials/) for clean separation
6. Going Further
-
hx-trigger for advanced event control (keyup delay:500ms)
-
hx-ext extensions (e.g., WebSockets, history)
-
Use HTMX in Django admin or dashboards to improve responsiveness
7. Conclusion
HTMX brings back the power of the server by letting Django do what it does best which is render HTML. With just a few attributes, you can create powerful, dynamic experiences without bloated frontend frameworks.
HTMX + Django = Clean, Fast, Simple.
