Hybrid solution for dynamic UX in Django without JS.

Why? New websites are dynamic for attractive to user. Using vue/angular/react isn't perfect solution for SEO and doesn't work without JS.

This solution allow creating dynamic website with small dependencies and full-server rendering. You can use dynamic forms as additional, and handle forms also traditionally. Then it will works with js and non-js browsers.

Installation

1. Install django-smooth and/or add to your requirements file.
2. Add 'django-smooth' to installed_apps in settings.
3. Add to start html template: {% load static %}
4. Add to end body:

<script
  src="https://code.jquery.com/jquery-3.6.0.min.js"
  integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4="
  crossorigin="anonymous"></script>

<script src="{% static 'smooth-core.js' %}"></script>

Usage

Use case: Cart incrementation.

To execute your form by smooth, add smooth="true" attribute in form. Like this:

<form method="post" smooth="true">

Mark your html element for manipulating by views:

<p smooth-id="cart-count">0</p>

In your view function or method of class add:

if request.is_ajax():
    response = SmoothResponse(
        actions=[
            SmoothAction(
                action_type=SmoothIncrement(val=1.0),
                elements=['cart-count']
            )
        ]
    ).dict()
    return JsonResponse(response)

More example coming soon.

Available actions

• SmoothIncrement and SmoothDecrement - val (float) parameter as increment/decrement value.
• SmoothRemove - without parameters.
• SmoothAddClass and SmoothRemoveClass - class_name (str) parameter as css class name.
