HTMX & TailwindCSS: Server-Driven UI (SDUI)

~14 min read  //  Django Series  //  Coding India

1. Deep Architecture

HTMX swaps server-rendered HTML fragments directly into the DOM, avoiding client-side JSON parsing. This reduces Javascript execution overhead and speeds up the first paint. Combined with Tailwind’s utility-first CSS, it simplifies frontend updates.

2. The Feynman Gatekeeper

[KNOWLEDGE CHECK] What is the difference in DOM updates between updating state in React and swapping HTML fragments with HTMX?

3. The Code

# views.py
from django.shortcuts import render

def video_status_partial(request, video_id):
    video = Video.objects.get(id=video_id)
    if request.headers.get("HX-Request"):
        return render(request, "sanjaya/partials/status.html", {"video": video})
    return render(request, "sanjaya/full_status.html", {"video": video})

4. The Funnel

Sanjaya Integration: Update the status indicator on the dashboard without reloading the page.
