`QuickUI` is a front-end rendering framework derived from [PDRenderKit](https://github.com/pardnchiu/PDRenderKit), focusing on enhancing front-end framework features.<br>
By integrating a virtual DOM, it rewrites the rendering logic to improve rendering efficiency, enabling faster data observation and automatic updates.<br>

This project removes the `prototype` extensions from `PDRenderKit` to ensure compatibility and performance, making it suitable for complex applications.<br>
It provides both `module` and non-`module` versions and changes the license from `GPL-3.0` in `PDRenderKit` to `MIT`.

## Features

- **Clear Architecture**: Separates UI from data logic, making it easier to maintain.
- **Code Simplicity**: Reduces redundant code and enhances readability.
- **Automatic Rendering**: Monitors data changes and updates automatically, minimizing manual operations.
- **Lightweight**: Maintains full functionality within a file size of less than `20kb`.

## Installation

- **Install from npm**
    ```bash
    npm i @pardnchiu/quickui
    ```
- **Include from CDN**
    - **Directly include `QuickUI`**
        ```html
        <!-- Version 0.6.0 and above -->
        <script src="https://cdn.jsdelivr.net/npm/@pardnchiu/quickui@[VERSION]/dist/QuickUI.js"></script>

        <!-- Version 0.5.4 and below -->

        ```javascript
        // Version 0.6.0 and above
        import { QUI } from "https://cdn.jsdelivr.net/npm/@pardnchiu/quickui@[VERSION]/dist/QuickUI.esm.js";
        
        // Version 0.5.4 and below
        import { QUI } from "https://cdn.jsdelivr.net/npm/pdquickui@[VERSION]/dist/PDQuickUI.module.js";
        ```

## Usage

- Initialize `QUI`
    ```Javascript
    const app = new QUI({
        id: "", // Specify rendering element
        data: {
            // Custom DATA
        },
        event: {
            // Custom EVENT
        },
        when: {
            before_render: function () {
                // Stop rendering
            },
            rendered: function () {
                // Rendered
            },
            before_update: function () {
                // Stop updating
            },
            updated: function () {
                // Updated
            },
            before_destroy: function () {
                // Stop destruction
            },
            destroyed: function () {
                // Destroyed
            }
        }
    });
    ```

## Overview
Automatic Rendering: Automatically reloads when data changes are detected.

<details>
<summary>Attributes Overview</summary>

| Attribute | Description |
| --- | --- |
| `{{value}}` | Inserts text into HTML tags and automatically updates with data changes. |
| `:path` | Used with the `temp` tag to load HTML fragments from external files into the current page. |
| `:html` | Replaces the element's `innerHTML` with text. |
| `:for` | Supports formats like `item in items`, `(item, index) in items`, `(key, value) in object`. Iterates over data collections to generate corresponding HTML elements. |
| `:if`<br>`:else-if`<br>`:elif`<br>`:else` | Displays or hides elements based on specified conditions, enabling branching logic. |
| `:model` | Binds data to form elements (e.g., `input`), updating data automatically when input changes. |
| `:hide` | Hides elements based on specific conditions. |
| `:animation` | Specifies transition effects for elements, such as `fade-in` or `expand`, to enhance user experience. |
| `:mask` | Controls block loading animations, supporting `true|false|1|0`, to enhance dynamic visual effects during loading. |
| `:[attr]` | Sets element attributes, such as `ID`, `class`, image source, etc.<br>Examples: `:id`/`:class`/`:src`/`:alt`/`:href`... |
| `:[css]` | Sets element CSS, such as margin, padding, etc.
Examples: `:background-color`, `:opacity`, `:margin`, `:top`, `:position`... |
| `@[event]` | Adds event listeners that trigger specified actions upon activation.<br>Examples: `@click`/`@input`/`@mousedown`... |
