🎯 Quick Example

from djust import LiveView, event_handler

class CounterView(LiveView):
    template_string = """
    <div>
        <h1>Count: {{ count }}</h1>
        <button dj-click="increment">+</button>
        <button dj-click="decrement">-</button>
    </div>
    """

    def mount(self, request, **kwargs):
        self.count = 0

    @event_handler
    def increment(self):
        self.count += 1  # Automatically updates client!

    @event_handler
    def decrement(self):
        self.count -= 1

That's it! No JavaScript needed. State changes automatically trigger minimal DOM updates.

🔄 How Reactivity Works

djust uses a Rust-powered Virtual DOM (VDOM) to diff server-rendered HTML and send only the changed patches over WebSocket. Understanding a few core attributes makes everything click.

Template Anatomy

{% load djust_tags %}
<!DOCTYPE html>
<html>
<head>
    {% djust_scripts %}              {# Loads ~5KB client JavaScript #}
</head>
<body dj-view="{{ dj_view_id }}">   {# Identifies the WebSocket session #}
    <div dj-root>                    {# Reactive boundary — only this is diffed #}
        <h1>Count: {{ count }}</h1>
        <button dj-click="increment">+</button>
    </div>
    {# Static content outside dj-root is never touched by VDOM patching #}
</body>
</html>
Attribute Where Purpose
{% djust_scripts %} <head> Injects client JavaScript
dj-view="{{ dj_view_id }}" <body> Connects page to WebSocket session
dj-root Inner <div> Marks the reactive region; only HTML inside is diffed and patched

Stable List Identity

For lists that can reorder or have items inserted/deleted, add data-key or dj-key on each item. djust uses this to emit MoveChild patches instead of remove-then-insert pairs — preserving DOM state (focus, scroll position, animations):

{% for item in items %}
<div data-key="{{ item.id }}">
    {{ item.name }}
    <button dj-click="delete" data-item-id="{{ item.id }}">Delete</button>
</div>
{% endfor %}

Without a key, djust diffs by position — correct, but produces more DOM mutations for reorders.

Common Pitfall: One-Sided {% if %} in Class Attributes

Using {% if %} without {% else %} inside an HTML attribute value can cause VDOM patching misalignment due to djust's branch-aware div-depth counting:

{# WRONG: one-sided if inside class attribute #}
<div class="card {% if active %}active{% endif %}">

{# CORRECT: use full if/else #}
<div class="card {% if active %}active{% else %}{% endif %}">

{# ALSO CORRECT: move conditional outside the tag #}
{% if active %}
<div class="card active">
{% else %}
<div class="card">
{% endif %}
    ...
</div>

This applies only to attribute values — {% if %} blocks in element content work fine.

See the VDOM Architecture guide and Template Cheat Sheet for full details.

🚀 Getting Started

Here's a complete walkthrough from zero to a working reactive counter in 5 steps.

Step 1 — Install

pip install djust django-channels

Step 2 — Add to INSTALLED_APPS and configure settings

In myproject/settings.py:

INSTALLED_APPS = [
    # ... your existing apps ...
    'channels',   # WebSocket support
    'djust',
]

ASGI_APPLICATION = 'myproject.asgi.application'

CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels.layers.InMemoryChannelLayer',
    }
}

Step 3 — Configure asgi.py

Replace myproject/asgi.py with:

import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from djust.websocket import LiveViewConsumer
from django.urls import path

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AuthMiddlewareStack(
        URLRouter([
            path('ws/live/', LiveViewConsumer.as_asgi()),
        ])
    ),
})

Step 4 — Add the URL route

In myproject/urls.py:

from django.urls import path
from myapp.views import CounterView

urlpatterns = [
    path('counter/', CounterView.as_live_view(), name='counter'),
]

Step 5 — Write the view and template

myapp/views.py:

from djust import LiveView, event_handler

class CounterView(LiveView):
    template_name = 'counter.html'

    def mount(self, request, **kwargs):
        self.count = 0

    @event_handler
    def increment(self):
        self.count += 1

    @event_handler
    def decrement(self):
        self.count -= 1

myapp/templates/counter.html:

{% load djust_tags %}
<!DOCTYPE html>
<html>
<head>
    <title>Counter</title>
    {% djust_scripts %}
</head>
<body dj-view="{{ dj_view_id }}">
    <div dj-root>
        <h1>Count: {{ count }}</h1>
        <button dj-click="increment">+</button>
        <button dj-click="decrement">-</button>
    </div>
</body>
</html>

Run with uvicorn myproject.asgi:application --reload and open /counter/. Clicking the buttons updates the count without a page reload — no JavaScript written, no build step.

📖 Documentation

Setup

  1. Add to INSTALLED_APPS:
INSTALLED_APPS = [
    # ...
    'channels',  # Required for WebSocket support
    'djust',
    # ...
]
  1. Configure ASGI application (asgi.py):
import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from djust.websocket import LiveViewConsumer
from django.urls import path

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AuthMiddlewareStack(
        URLRouter([
            path('ws/live/', LiveViewConsumer.as_asgi()),
        ])
    ),
})

ASGI_APPLICATION = 'myproject.asgi.application'

CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels.layers.InMemoryChannelLayer'
    }
}

Creating LiveViews

Class-Based LiveView

from djust import LiveView, event_handler

class TodoListView(LiveView):
    template_name = 'todos.html'  # Or use template_string

    def mount(self, request, **kwargs):
        """Called when view is first loaded"""
        self.todos = []

    @event_handler
    def add_todo(self, text):
        """Event handler - called from client"""
        self.todos.append({'text': text, 'done': False})

    @event_handler
    def toggle_todo(self, index):
        self.todos[index]['done'] = not self.todos[index]['done']

Function-Based LiveView

from djust import live_view

@live_view(template_name='counter.html')
def counter_view(request):
    count = 0

    def increment():
        nonlocal count
        count += 1

    return locals()  # Returns all local variables as context

Template Syntax

djust supports Django template syntax with event binding:

<!-- Variables -->
<h1>{{ title }}</h1>

<!-- Filters (all 57 Django built-in filters supported) -->
<p>{{ text|upper }}</p>
<p>{{ description|truncatewords:20 }}</p>
<a href="?q={{ query|urlencode }}">Search</a>
{{ body|urlize }}  {# No |safe needed — djust's Rust engine auto-marks urlize output as safe via safe_output_filters. Unlike standard Django where you'd add |safe, djust handles this automatically. #}

<!-- Control flow -->
{% if show %}
    <div>Visible</div>
{% endif %}

{% if count > 10 %}
    <div>Many items!</div>
{% endif %}

{% for item in items %}
    <li>{{ item }}</li>
{% endfor %}

<!-- URL resolution -->
<a href="{% url 'myapp:detail' pk=item.id %}">View</a>

<!-- Template includes -->
{% include "partials/header.html" %}

<!-- Event binding -->
<button dj-click="increment">Click me</button>
<input dj-input="on_search" type="text" />
<form dj-submit="submit_form">
    <input name="email" />
    <button type="submit">Submit</button>
</form>

Django migration note: In standard Django, urlize requires |safe to render its HTML output. djust's Rust template engine automatically marks urlize, urlizetrunc, and unordered_list as safe (via safe_output_filters in the renderer) because these filters handle their own HTML escaping internally. Adding |safe after them is unnecessary.

Supported Events

  • dj-click - Click events
  • dj-input - Input events (passes value)
  • dj-change - Change events (passes value)
  • dj-submit - Form submission (passes form data as dict)

Reusable Components

djust provides a powerful component system with automatic state management and stable component IDs.

Basic Component Example

from djust.components import AlertComponent

class MyView(LiveView):
    def mount(self, request):
        # Components get automatic IDs based on attribute names
        self.alert_success = AlertComponent(
            message="Operation successful!",
            type="success",
            dismissible=True
        )
        # component_id automatically becomes "alert_success"

Component ID Management

Components automatically receive a stable component_id based on their attribute name in your view. This eliminates manual ID management:

# When you write:
self.alert_success = AlertComponent(message="Success!")

# The framework automatically:
# 1. Sets component.component_id = "alert_success"
# 2. Persists this ID across renders and events
# 3. Uses it in HTML: data-component-id="alert_success"
# 4. Routes events back to the correct component

Why it works:

  • The attribute name (alert_success) is already unique within your view
  • It's stable across re-renders and WebSocket reconnections
  • Event handlers can reference components by their attribute names
  • No manual ID strings to keep in sync

Event Routing Example:

class MyView(LiveView):
    def mount(self, request):
        self.alert_warning = AlertComponent(
            message="Warning message",
            dismissible=True
        )

    @event_handler
    def dismiss(self, component_id: str = None):
        """Handle dismissal - automatically routes to correct component"""
        if component_id and hasattr(self, component_id):
            component = getattr(self, component_id)
            if hasattr(component, 'dismiss'):
                component.dismiss()  # component_id="alert_warning"

When the dismiss button is clicked, the client sends component_id="alert_warning", and the handler uses getattr(self, "alert_warning") to find the component.

Creating Custom Components

from djust import Component, register_component, event_handler

@register_component('my-button')
class Button(Component):
    template = '<button dj-click="on_click">{{ label }}</button>'

    def __init__(self, label="Click"):
        super().__init__()
        self.label = label
        self.clicks = 0

    @event_handler
    def on_click(self):
        self.clicks += 1
        print(f"Clicked {self.clicks} times!")

Decorators

from djust import LiveView, event_handler, reactive

class MyView(LiveView):
    @event_handler
    def handle_click(self):
        """Marks method as event handler"""
        pass

    @reactive
    def count(self):
        """Reactive property - auto-triggers updates"""
        return self._count

    @count.setter
    def count(self, value):
        self._count = value

Configuration

Configure djust in your Django settings.py:

LIVEVIEW_CONFIG = {
    # Transport mode
    'use_websocket': True,  # Set to False for HTTP-only mode (no WebSocket dependency)

    # Debug settings
    'debug_vdom': False,  # Enable detailed VDOM patch logging (for troubleshooting)

    # Serialization (issue #292)
    'strict_serialization': False,  # Raise TypeError for non-serializable state values (recommended in development)

    # CSS Framework
    'css_framework': 'bootstrap5',  # Options: 'bootstrap5', 'tailwind', None
}

Common Configuration Options:

Option Default Description
use_websocket True Use WebSocket transport (requires Django Channels)
debug_vdom False Enable detailed VDOM debugging logs
strict_serialization False Raise TypeError for non-serializable state (recommended in dev)
css_framework 'bootstrap5' CSS framework for components

CSS Framework Setup:

For Tailwind CSS (recommended), use the one-command setup:

python manage.py djust_setup_css tailwind

This auto-detects template directories, creates config files, and builds your CSS. For production:

python manage.py djust_setup_css tailwind --minify

See the CSS Framework Guide for detailed setup instructions, Bootstrap configuration, and CI/CD integration.

Debug Mode:

When troubleshooting VDOM issues, enable debug logging:

# In settings.py
LIVEVIEW_CONFIG = {
    'debug_vdom': True,
}

# Or programmatically
from djust.config import config
config.set('debug_vdom', True)

This will log:

  • Server-side: Patch generation details (stderr)
  • Client-side: Patch application and DOM traversal (browser console)

State Management

djust provides Python-only state management decorators that eliminate the need for manual JavaScript.

🚀 Quick Start (5 minutes)

Build a debounced search in 8 lines of Python (no JavaScript):

from djust import LiveView
from djust.decorators import debounce

class ProductSearchView(LiveView):
    template_string = """
    <input dj-input="search" placeholder="Search products..." />
    <div>{% for p in results %}<div>{{ p.name }}</div>{% endfor %}</div>
    """

    def mount(self, request):
        self.results = []

    @debounce(wait=0.5)  # Wait 500ms after typing stops
    def search(self, query: str = "", **kwargs):
        self.results = Product.objects.filter(name__icontains=query)[:10]

That's it! Server only queries after you stop typing. Add @optimistic for instant UI updates, @cache(ttl=300) to cache responses for 5 minutes.

Available Decorators

Decorator Use When Example
@debounce(wait) User is typing Search, autosave
@throttle(interval) Rapid events Scroll, resize
@optimistic Instant feedback Counter, toggle
@cache(ttl, key_params) Repeated queries Autocomplete
@client_state(keys) Multi-component Dashboard filters
@background Long operations AI generation, file processing
DraftModeMixin Auto-save forms Contact form

Quick Decision Matrix:

  • Typing in input? → @debounce(0.5)
  • Scrolling/resizing? → @throttle(0.1)
  • Need instant UI update? → @optimistic
  • Same query multiple times? → @cache(ttl)
  • Multiple components? → @client_state([keys])
  • Long-running work? → @background or self.start_async(callback)
  • Auto-save forms? → DraftModeMixin

🧭 Navigation Patterns

djust provides three navigation mechanisms for building multi-view applications without full page reloads:

When to Use What

Scenario Use Why
Filter/sort/paginate within same view dj-patch / live_patch() No remount, URL stays bookmarkable
Navigate to a different LiveView dj-navigate / live_redirect() Same WebSocket, no page reload
Link to non-LiveView page Standard <a href> Full page load needed

Quick Decision Tree

Use this flowchart when choosing a navigation method:

Is this a direct user click on a link?
├─ Yes → Is it the same view (filter/sort)?
│   ├─ Yes → Use dj-patch
│   └─ No → Use dj-navigate
│
└─ No → Is navigation conditional on server logic?
    ├─ Yes → Use live_redirect() in @event_handler
    │   Examples: form validation, auth checks, async operations
    └─ No → You probably need dj-navigate (see anti-pattern below)

⚠️ Anti-Pattern: Don't Use dj-click for Navigation

This is the most common mistake when building multi-view djust apps. Using dj-click to trigger a handler that immediately calls live_redirect() creates an unnecessary round-trip.

❌ Wrong — using dj-click to trigger a handler that calls live_redirect():

# Anti-pattern: Handler does nothing but navigate
@event_handler()
def go_to_item(self, item_id, **kwargs):
    self.live_redirect(f"/items/{item_id}/")  # Wasteful round-trip!
<!-- Wrong: Forces WebSocket round-trip just to navigate -->
<button dj-click="go_to_item" dj-value-item_id="{{ item.id }}">View</button>

What actually happens:

  1. User clicks button → Client sends WebSocket message (50-100ms)
  2. Server receives message, processes handler (10-50ms)
  3. Server responds with live_redirect command (50-100ms)
  4. Client finally navigates to new view Total: 110-250ms + handler processing time

✅ Right — using dj-navigate directly:

<!-- Right: Client navigates immediately, no server round-trip -->
<a dj-navigate="/items/{{ item.id }}/">View Item</a>

What happens:

  1. User clicks link → Client navigates directly Total: ~10ms (just DOM updates)

Why it matters:

  • Performance: 10-20x faster navigation
  • Network efficiency: Saves WebSocket bandwidth
  • User experience: Instant response, no loading indicators needed
  • Simplicity: Less code, fewer moving parts

When to Use live_redirect() in Handlers

Use handlers for navigation only when navigation depends on server-side logic or validation:

✅ Conditional navigation after form validation:

@event_handler()
def submit_form(self, **kwargs):
    if self.form.is_valid():
        self.form.save()
        self.live_redirect("/success/")  # OK: Conditional on validation
    else:
        # Stay on form to show errors
        pass

✅ Navigation based on auth/permissions:

@event_handler()
def view_sensitive_data(self, **kwargs):
    if not self.request.user.has_perm('app.view_sensitive'):
        self.live_redirect("/access-denied/")  # OK: Auth check required
        return
    self.show_sensitive = True

✅ Navigation after async operations:

@event_handler()
async def create_and_view_item(self, name, **kwargs):
    item = await Item.objects.acreate(name=name, owner=self.request.user)
    self.live_redirect(f"/items/{item.id}/")  # OK: Navigate to newly created item

✅ Multi-step wizard logic:

@event_handler()
def next_step(self, **kwargs):
    if self.current_step == "payment" and not self.payment_valid:
        # Stay on payment step if invalid
        return
    self.current_step = self.get_next_step()
    self.live_patch(params={"step": self.current_step})  # OK: Conditional flow

Common theme: The handler does meaningful work before navigating. If your handler only calls live_redirect(), use dj-navigate instead.

Quick Example: Multi-View App

from djust import LiveView
from djust.mixins.navigation import NavigationMixin
from djust.decorators import event_handler

class ProductListView(NavigationMixin, LiveView):
    template_string = """
    <!-- Filter within same view: use dj-patch -->
    <a dj-patch="?category=electronics">Electronics</a>
    <a dj-patch="?category=books">Books</a>

    <div>
        {% for product in products %}
            <!-- Navigate to different view: use dj-navigate -->
            <a dj-navigate="/products/{{ product.id }}/">{{ product.name }}</a>
        {% endfor %}
    </div>
    """

    def mount(self, request, **kwargs):
        self.category = "all"
        self.products = []

    def handle_params(self, params, uri):
        """Called when URL changes via dj-patch or browser back/forward"""
        self.category = params.get("category", "all")
        self.products = Product.objects.filter(category=self.category)

Developer Tooling

Debug Panel

Interactive debugging tool for LiveView development (DEBUG mode only):

# In settings.py
DEBUG = True  # Debug panel automatically enabled

Open: Press Ctrl+Shift+D (Windows/Linux) or Cmd+Shift+D (Mac), or click the 🐞 floating button

Features:

  • 🔍 Event Handlers - Discover all handlers with parameters, types, and descriptions
  • 📊 Event History - Real-time log with timing metrics (e.g., search • 45.2ms)
  • VDOM Patches - Monitor DOM updates with sub-millisecond precision
  • 🔬 Variables - Inspect current view state

Learn More:

Event Handlers

Always use @event_handler decorator for auto-discovery and validation:

from djust.decorators import event_handler

@event_handler()
def search(self, value: str = "", **kwargs):
    """Search handler - description shown in debug panel"""
    self.search_query = value

Parameter Convention: Use value for form inputs (dj-input, dj-change events):

# ✅ Correct - matches what form events send
@event_handler()
def search(self, value: str = "", **kwargs):
    self.search_query = value

# ❌ Wrong - won't receive input value
@event_handler()
def search(self, query: str = "", **kwargs):
    self.search_query = query  # Always "" (default)

  • 💜 GitHub Sponsors - Monthly support from $5/month

Your support helps us maintain and improve djust for everyone!

🤝 Contributing

Contributions welcome! Please read CONTRIBUTING.md first.

Areas we'd love help with:

  • More example applications
  • Performance optimizations
  • Documentation improvements
  • Browser compatibility testing

📝 Roadmap

  • Template inheritance ({% extends %})
  • {% url %} and {% include %} tags
  • Comparison operators in {% if %} tags
  • All 57 Django built-in template filters
  • Security hardening (WebSocket origin validation, HMAC signing, rate limiting)
  • Developer debug panel with event history and VDOM inspection
  • Reusable component library (djust_components crate)
  • JIT pipeline improvements and stale-closure fixes
  • Authentication & authorization (view-level + handler-level)
  • File upload handling
  • Server-sent events (SSE) fallback
  • React/Vue component compatibility
  • TypeScript definitions (djust.d.ts shipped with the package)
  • Redis-backed session storage
  • Horizontal scaling support

🔒 Security

  • CSRF protection via Django middleware
  • XSS protection via automatic template escaping (Rust engine escapes all variables by default)
  • HTML-producing filters (urlize, urlizetrunc, unordered_list) handle their own escaping internally — the Rust engine's safe_output_filters whitelist prevents double-escaping, so |safe is never needed with these filters
  • WebSocket authentication via Django sessions
  • WebSocket origin validation and HMAC message signing (v0.2.1)
  • Per-view and global rate limiting support
  • Configurable allowed origins for WebSocket connections
  • View-level auth enforcement (login_required, permission_required) before mount()
  • Handler-level @permission_required for protecting individual event handlers
  • djust_audit command and djust.S005 system check for auth posture visibility
