** What is HTML over the Wire?

HTML over the Wire, or HTML over WebSockets, is a strategy for creating real-time SPAs by establishing a WebSocket connection between a client and server. It allows JavaScript to request actions—its only responsibility is to handle events—while the backend handles the business logic and renders HTML. This means you can create dynamic pages without reloading, without AJAX or APIs. This technology provides a secure, stable, and low-latency connection for real-time web applications.

#+ATTR_HTML: :class center-block image image--home
[[#/img/step-2.avif][Architecture receive]]

** What is Django LiveView? 🚀

Django LiveView is a framework for creating real-time, interactive web applications entirely in Python 🐍, inspired by [[https://hexdocs.pm/phoenix_live_view/][Phoenix LiveView]] and [[https://laravel-livewire.com/][Laravel Livewire]]. It is built on top of Django Channels.

Build rich, dynamic user experiences ✨ with server-rendered HTML without writing a single line of JavaScript. Perfect for Django developers who want real-time features ⚡ without the complexity of a separate frontend framework.

Let's illustrate with an example. I want to print article number 2.

1. A WebSocket connection (a channel) is established between the client and the server.

2. JavaScript sends a message via WebSocket to the server (Django).

#+ATTR_HTML: :class center-block image image--home
[[#/img/step-3.avif][Send string]]

3. Django interprets the message and renders the HTML of the article through the template system and the database.

4. Django sends the HTML to JavaScript via the channel and specifies which selector to embed it in.

#+ATTR_HTML: :class center-block image image--home
[[#/img/step-4.avif][Send JSON]]

5. JavaScript renders the received HTML in the indicated selector.

#+ATTR_HTML: :class center-block image image--home
[[#/img/step-5.avif][Place HTML]]

The same process is repeated for each action, such as clicking a button, submitting a form, etc.

* Install
:PROPERTIES:
:ONE: one-custom-default-doc
:CUSTOM_ID: /docs/install/
:TITLE: Install
:DESCRIPTION: Install Django LiveView.
:NAVIGATOR-ACTIVE: docs
:END:

** Requirements

- Python 3.10+
- Django 4.2+
- Redis (for Channels layer)
- Channels 4.0+

** Installation

Install Django LiveView with pip:

#+BEGIN_SRC sh
pip install django-liveview
#+END_SRC

** Configure Django

Add to your ~settings.py~:

#+BEGIN_SRC python
# settings.py
INSTALLED_APPS = [
    "daphne",  # Must be first for ASGI support
    "channels",
    "liveview",
    # ... your other apps
]

# ASGI configuration
ASGI_APPLICATION = "your_project.asgi.application"

# Configure Channels with Redis
CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("127.0.0.1", 6379)],
        },
    },
}
#+END_SRC

** Setup ASGI routing

Create or update ~asgi.py~:

#+BEGIN_SRC python
# asgi.py
import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from channels.security.websocket import AllowedHostsOriginValidator
from liveview.routing import get_liveview_urlpatterns

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "your_project.settings")

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AllowedHostsOriginValidator(
        AuthMiddlewareStack(
            URLRouter(
                get_liveview_urlpatterns()
            )
        )
    ),
})
#+END_SRC

** Add JavaScript to your base template

#+BEGIN_SRC html
<!-- templates/base.html -->
{% load static %}
<!DOCTYPE html>
<html lang="en" data-room="{% if request.user.is_authenticated %}{{ request.user.id }}{% else %}anonymous{% endif %}">
<head>
    <meta charset="UTF-8">
    <title>{% block title %}My Site{% endblock %}</title>
</head>
<body data-controller="page">
    {% block content %}{% endblock %}

    <!-- Django LiveView JavaScript -->
    <script src="{% static 'liveview/liveview.min.js' %}" defer></script>
</body>
</html>
#+END_SRC

**Important attributes:**
- ~data-room~ on ~<html>~ — unique identifier for WebSocket room (user-specific or shared)
- ~data-controller="page"~ on ~<body>~ — activates the Stimulus controller

We strongly recommend that you follow the [[#/tutorial/][Tutorial]] to see the installation in action.

* Handlers
:PROPERTIES:
:ONE: one-custom-default-doc
:CUSTOM_ID: /docs/handlers/
:TITLE: Handlers
:DESCRIPTION: LiveView handlers of Django LiveView.
:NAVIGATOR-ACTIVE: docs
:END:

Handlers are Python functions that respond to WebSocket messages from the client. They contain your business logic and can render HTML, update the database, broadcast to multiple users, and more.

** Creating Handlers

Use the ~@liveview_handler~ decorator to register functions that can be called from the client:

#+BEGIN_SRC python
from liveview import liveview_handler, send
from django.template.loader import render_to_string

@liveview_handler("say_hello")
def say_hello(consumer, content):
    """
    Args:
        consumer: WebSocket consumer instance
        content: dict with:
            - function: str - the function name
            - data: dict - custom data from data-data-* attributes
            - form: dict - form input values
            - lang: str - current language
            - room: str - room identifier
    """
    name = content.get("form", {}).get("name", "World")

    html = render_to_string("hello_message.html", {
        "message": f"Hello, {name}!"
    })

    send(consumer, {
        "target": "#greeting",
        "html": html
    })
#+END_SRC

** Auto-discovery

Django LiveView automatically discovers handlers in ~liveview_components/~ directories within your installed apps:

#+BEGIN_SRC
my_app/
├── liveview_components/
│   ├── __init__.py
│   ├── users.py
│   ├── posts.py
│   └── comments.py
#+END_SRC

Handlers are loaded on startup with this output:
#+BEGIN_SRC
✓ Imported: my_app.liveview_components.users
✓ Imported: my_app.liveview_components.posts
✓ Imported: my_app.liveview_components.comments
#+END_SRC

** Using the send() function

The ~send()~ function sends data back to the client with many options:

*** Replace HTML (Basic Update)

#+BEGIN_SRC python
@liveview_handler("update_content")
def update_content(consumer, content):
    send(consumer, {
        "target": "#my-element",
        "html": "<p>New content</p>"
    })
#+END_SRC

*** Append HTML

#+BEGIN_SRC python
@liveview_handler("add_item")
def add_item(consumer, content):
    send(consumer, {
        "target": "#items-list",
        "html": "<li>New item</li>",
        "append": True  # Adds to the end
    })
#+END_SRC

*** Remove Element

#+BEGIN_SRC python
@liveview_handler("delete_item")
def delete_item(consumer, content):
    item_id = content["data"]["id"]
    # Delete from database...

    send(consumer, {
        "target": f"#item-{item_id}",
        "remove": True
    })
#+END_SRC

*** Update URL and Title

#+BEGIN_SRC python
@liveview_handler("navigate")
def navigate(consumer, content):
    send(consumer, {
        "target": "#content",
        "html": render_to_string("new_page.html"),
        "url": "/new-page/",
        "title": "New Page Title"
    })
#+END_SRC

*** Scroll Management

#+BEGIN_SRC python
@liveview_handler("show_section")
def show_section(consumer, content):
    send(consumer, {
        "target": "#content",
        "html": render_to_string("section.html"),
        "scroll": "#section-2"  # Smooth scroll to element
    })

@liveview_handler("back_to_top")
def back_to_top(consumer, content):
    send(consumer, {
        "target": "#content",
        "html": render_to_string("content.html"),
        "scrollTop": True  # Scroll to top of page
    })
#+END_SRC

* Frontend Integration
:PROPERTIES:
:ONE: one-custom-default-doc
:CUSTOM_ID: /docs/frontend/
:TITLE: Frontend Integration
:DESCRIPTION: How to call handlers from the frontend.
:NAVIGATOR-ACTIVE: docs
:END:

The frontend is responsible for capturing events and sending messages over WebSocket. No logic, rendering, or state is in the frontend—the backend does all the work.

Django LiveView uses [[https://stimulus.hotwired.dev/][Stimulus]] to manage DOM events and avoid collisions. The JavaScript assets are bundled within the package.

** Calling Handlers

To call a handler from a button click:

#+BEGIN_SRC html
<button
    data-liveview-function="say_hello"
    data-action="click->page#run">
    Say Hello
</button>
#+END_SRC

- ~data-liveview-function~ — The handler name registered with ~@liveview_handler~
- ~data-action~ — Stimulus action (event->controller#action)

** Sending Form Data

All form fields are automatically extracted and sent in ~content["form"]~:

#+BEGIN_SRC html
<div>
    <input type="text" name="name" placeholder="Enter your name">
    <button
        data-liveview-function="say_hello"
        data-action="click->page#run">
        Submit
    </button>
</div>
#+END_SRC

** Sending Custom Data

Use ~data-data-*~ attributes to send additional data:

#+BEGIN_SRC html
<button
    data-liveview-function="open_modal"
    data-data-modal-id="123"
    data-data-user-id="456"
    data-action="click->page#run">
    Open Modal
</button>
#+END_SRC

Access in Python:

#+BEGIN_SRC python
@liveview_handler("open_modal")
def open_modal(consumer, content):
    data = content.get("data", {})
    modal_id = data.get("modalId")      # from modal-id
    user_id = data.get("userId")        # from user-id
#+END_SRC

** Stimulus Actions Reference

Available Stimulus actions:

- ~data-action="click->page#run"~ — Execute LiveView function on click
- ~data-action="input->page#run"~ — Execute on input change (real-time)
- ~data-action="submit->page#run"~ — Execute on form submit
- ~data-action="change->page#run"~ — Execute on change event
- ~data-action="blur->page#run"~ — Execute when element loses focus
- ~data-action="page#stop"~ — Stop event propagation

* Forms
:PROPERTIES:
:ONE: one-custom-default-doc
:CUSTOM_ID: /docs/forms/
:TITLE: Forms
:DESCRIPTION: Form handling in Django LiveView.
:NAVIGATOR-ACTIVE: docs
:END:

Django LiveView works seamlessly with Django forms. Form data is sent via WebSocket instead of HTTP.

** Form Handling Example

Python handler:

#+BEGIN_SRC python
@liveview_handler("submit_contact")
def submit_contact(consumer, content):
    from .forms import ContactForm

    form = ContactForm(content["form"])

    if form.is_valid():
        # Save to database
        contact = form.save()

        # Show success message
        html = render_to_string("contact_success.html", {
            "message": "Thank you! We'll be in touch."
        })
    else:
        # Show form with errors
        html = render_to_string("contact_form.html", {
            "form": form
        })

    send(consumer, {
        "target": "#contact-container",
        "html": html
    })
#+END_SRC

HTML template:

#+BEGIN_SRC html
<div id="contact-container">
    <form>
        <input type="text" name="name" placeholder="Name" required>
        <input type="email" name="email" placeholder="Email" required>
        <textarea name="message" placeholder="Message" required></textarea>

        <button
            data-liveview-function="submit_contact"
            data-action="click->page#run"
            type="button">
            Submit
        </button>
    </form>
</div>
#+END_SRC

** Real-time Validation

#+BEGIN_SRC python
@liveview_handler("validate_field")
def validate_field(consumer, content):
    field_name = content["data"]["field"]
    field_value = content["form"].get(field_name, "")

    # Validate
    error = None
    if field_name == "email" and "@" not in field_value:
        error = "Invalid email address"
    elif field_name == "name" and len(field_value) < 3:
        error = "Name must be at least 3 characters"

    # Show error or success
    html = f'<span class="{"error" if error else "success"}">{error or "✓"}</span>'

    send(consumer, {
        "target": f"#error-{field_name}",
        "html": html
    })
#+END_SRC

#+BEGIN_SRC html
<input
    type="text"
    name="email"
    data-liveview-function="validate_field"
    data-data-field="email"
    data-action="blur->page#run">
<span id="error-email"></span>
#+END_SRC

* Broadcasting
:PROPERTIES:
:ONE: one-custom-default-doc
:CUSTOM_ID: /docs/broadcasting/
:TITLE: Broadcasting
:DESCRIPTION: Broadcasting updates to multiple users.
:NAVIGATOR-ACTIVE: docs
:END:

Send updates to all connected clients using the ~broadcast~ parameter:

** Simple Broadcast

#+BEGIN_SRC python
@liveview_handler("notify_all")
def notify_all(consumer, content):
    message = content["form"]["message"]

    html = render_to_string("notification.html", {
        "message": message
    })

    send(consumer, {
        "target": "#notifications",
        "html": html,
        "append": True
    }, broadcast=True)  # Sends to ALL connected users
#+END_SRC

** Background Thread Broadcast with Auto-removal

#+BEGIN_SRC python
from threading import Thread
from time import sleep
from uuid import uuid4

@liveview_handler("send_notification")
def send_notification(consumer, content):
    notification_id = str(uuid4().hex)
    message = "New update available!"

    def broadcast_notification():
        # Send notification
        html = render_to_string("notification.html", {
            "id": notification_id,
            "message": message
        })

        send(consumer, {
            "target": "#notifications",
            "html": html,
            "append": True
        }, broadcast=True)

        # Remove after 5 seconds
        sleep(5)
        send(consumer, {
            "target": f"#notification-{notification_id}",
            "remove": True
        }, broadcast=True)

    Thread(target=broadcast_notification).start()
#+END_SRC

:END:

** Intersection Observer (Infinite Scroll)

Trigger functions when elements enter or exit the viewport:

#+BEGIN_SRC python
ITEMS_PER_PAGE = 10

@liveview_handler("load_more")
def load_more(consumer, content):
    page = int(content["data"].get("page", 1))

    # Fetch items
    start = (page - 1) * ITEMS_PER_PAGE
    end = start + ITEMS_PER_PAGE
    items = Item.objects.all()[start:end]
    is_last_page = end >= Item.objects.count()

    # Append items to list
    send(consumer, {
        "target": "#items-list",
        "html": render_to_string("items_partial.html", {
            "items": items
        }),
        "append": True
    })

    # Update or remove intersection observer trigger
    if is_last_page:
        html = ""
    else:
        html = render_to_string("load_trigger.html", {
            "next_page": page + 1
        })

    send(consumer, {
        "target": "#load-more-trigger",
        "html": html
    })
#+END_SRC

HTML template:

#+BEGIN_SRC html
<!-- load_trigger.html -->
<div
    data-liveview-intersect-appear="load_more"
    data-data-page="{{ next_page }}"
    data-liveview-intersect-threshold="200">
    <p>Loading more...</p>
</div>
#+END_SRC

**Attributes:**
- ~data-liveview-intersect-appear="function_name"~ — Call when element appears
- ~data-liveview-intersect-disappear="function_name"~ — Call when element disappears
- ~data-liveview-intersect-threshold="200"~ — Trigger 200px before entering viewport (default: 0)

** Auto-focus

Automatically focus elements after rendering:

#+BEGIN_SRC html
<input
    type="text"
    name="title"
    value="{{ item.title }}"
    data-liveview-focus="true">
#+END_SRC

** Init Functions

Execute functions when elements are first rendered:

#+BEGIN_SRC html
<div
    data-liveview-init="init_counter"
    data-data-counter-id="1"
    data-data-initial-value="0">
    <span id="counter-1-value"></span>
</div>
#+END_SRC

** Debounce

Reduce server calls by adding a delay before sending requests. Perfect for search inputs and real-time validation:

#+BEGIN_SRC html
<input
    type="search"
    name="search"
    data-liveview-function="search_articles"
    data-liveview-debounce="500"
    data-action="input->page#run"
    placeholder="Search articles...">
#+END_SRC

The ~data-liveview-debounce="500"~ attribute waits 500ms after the user stops typing before sending the request. This dramatically reduces server load and provides a better user experience.

**Example: Real-time search with debounce**

#+BEGIN_SRC python
from liveview import liveview_handler, send
from django.template.loader import render_to_string

@liveview_handler("search_articles")
def search_articles(consumer, content):
    query = content["form"]["search"]
    articles = Article.objects.filter(title__icontains=query)

    html = render_to_string("search_results.html", {
        "articles": articles
    })

    send(consumer, {
        "target": "#search-results",
        "html": html
    })
#+END_SRC

Without debounce, typing "python" would send 6 requests (one per letter). With ~data-liveview-debounce="500"~, it sends only 1 request after the user stops typing for 500ms.

** Middleware System

Add middleware to run before handlers for authentication, logging, or rate limiting:

#+BEGIN_SRC python
from liveview import liveview_registry, send

def auth_middleware(consumer, content, function_name):
    """Check if user is authenticated before running handler"""
    user = consumer.scope.get("user")

    if not user or not user.is_authenticated:
        send(consumer, {
            "target": "#error",
            "html": "<p>You must be logged in</p>"
        })
        return False  # Cancel handler execution

    return True  # Continue to handler

def logging_middleware(consumer, content, function_name):
    """Log all handler calls"""
    import logging
    logger = logging.getLogger(__name__)

    user = consumer.scope.get("user")
    logger.info(f"Handler '{function_name}' called by {user}")

    return True  # Continue to handler

# Register middleware
liveview_registry.add_middleware(auth_middleware)
liveview_registry.add_middleware(logging_middleware)
#+END_SRC

* Internationalization

:ONE: one-custom-default-doc
:CUSTOM_ID: /docs/internationalization/
:TITLE: Internationalization
:DESCRIPTION: Multi-language support in Django LiveView.
:NAVIGATOR-ACTIVE: docs
:END:

Django LiveView automatically passes the current language to handlers:

#+BEGIN_SRC python
from django.utils import translation

@liveview_handler("show_content")
def show_content(consumer, content):
    # Get language from WebSocket message
    lang = content.get("lang", "en")

    # Activate language for this context
    translation.activate(lang)

    try:
        html = render_to_string("content.html", {
            "title": _("Welcome"),
            "message": _("This content is in your language")
        })

        send(consumer, {
            "target": "#content",
            "html": html
        })
    finally:
        # Always deactivate to avoid side effects
        translation.deactivate()
#+END_SRC

The language is automatically detected from the ~<html>~ tag:

#+BEGIN_SRC html
{% load static i18n %}
<!doctype html>{% get_current_language as CURRENT_LANGUAGE %}
<html lang="{{ CURRENT_LANGUAGE }}">
#+END_SRC

:DESCRIPTION: Frequently asked questions about Django LiveView.
:NAVIGATOR-ACTIVE: docs
:END:

** Do I need to know JavaScript to use Django LiveView?

No, you don't need to. You can create SPAs without using APIs, without JavaScript, and without learning anything new. If you know Python, you know how to use Django LiveView.

** Can I use JavaScript?

Yes, you can. You can use JavaScript to enhance your application, but it's not required for basic functionality.

** Can I use Django's native tools?

Of course. You can still use all of Django's native tools, such as its ORM, forms, authentication, admin, etc.

** Do I need to use React, Vue, Angular or any other frontend framework?

No. All logic, rendering and state is in the backend.

** Can I use Django REST Framework or GraphQL?

Yes, you can use both alongside Django LiveView.

** What's the difference between v0.1.0 and v2.0.0?

v2.0.0 is a complete rewrite with a much simpler API:
- Module name changed from ~django_liveview~ to ~liveview~ for cleaner imports
- Simpler decorator-based API with ~@liveview_handler~
- Built-in auto-discovery of handlers
- JavaScript assets bundled within the package
- More comprehensive documentation

** Who finances the project?

# ASGI configuration
ASGI_APPLICATION = "your_project.asgi.application"

# Configure Channels with Redis
CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("127.0.0.1", 6379)],
        },
    },
}
#+END_SRC

** Step 3: Setup ASGI routing

Create or update ~asgi.py~:

#+BEGIN_SRC python
# asgi.py
import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from channels.security.websocket import AllowedHostsOriginValidator
from liveview.routing import get_liveview_urlpatterns

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "your_project.settings")

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AllowedHostsOriginValidator(
        AuthMiddlewareStack(
            URLRouter(
                get_liveview_urlpatterns()
            )
        )
    ),
})
#+END_SRC

** Step 4: Add JavaScript to your base template

#+BEGIN_SRC html
<!-- templates/base.html -->
{% load static %}
<!DOCTYPE html>
<html lang="en" data-room="{% if request.user.is_authenticated %}{{ request.user.id }}{% else %}anonymous{% endif %}">
<head>
    <meta charset="UTF-8">
    <title>{% block title %}My Site{% endblock %}</title>
</head>
<body data-controller="page">
    {% block content %}{% endblock %}

    <!-- Django LiveView JavaScript -->
    <script src="{% static 'liveview/liveview.min.js' %}" defer></script>
</body>
</html>
#+END_SRC

** Step 5: Create your first LiveView handler

Create ~app/liveview_components/hello.py~:

#+BEGIN_SRC python
# app/liveview_components/hello.py
from liveview import liveview_handler, send
from django.template.loader import render_to_string

@liveview_handler("say_hello")
def say_hello(consumer, content):
    """Handle 'say_hello' function from client"""
    name = content.get("form", {}).get("name", "World")

    html = render_to_string("hello_message.html", {
        "message": f"Hello, {name}!"
    })

    send(consumer, {
        "target": "#greeting",
        "html": html
    })
#+END_SRC

Create the template ~templates/hello_message.html~:

#+BEGIN_SRC html
<h1>{{ message }}</h1>
#+END_SRC

** Step 6: Use it in your page

#+BEGIN_SRC html
<!-- templates/hello_page.html -->
{% extends "base.html" %}

{% block content %}
<div>
    <input type="text" name="name" placeholder="Enter your name">
    <button
        data-liveview-function="say_hello"
        data-action="click->page#run">
        Say Hello
    </button>

    <div id="greeting">
        <h1>Hello, World!</h1>
    </div>
</div>
{% endblock %}
#+END_SRC

** Step 7: Run your project

#+BEGIN_SRC sh
# Run Django with Daphne (ASGI server)
python manage.py runserver
#+END_SRC
