Frenzy UI

Vanilla web components for things I and maybe you need.

Components

Frenzy UI is a collection of lightweight, dependency-free web components designed for ease of use and flexibility.

Currently, the following components are available:

• fz-carousel: A flexible and touch-friendly carousel/slider component.
• fz-color-picker (internally ColorChanger): A component to change the background color of its first slotted child element, with an interactive color picker button.
• fz-edit-image: A component that wraps a slotted <img> element, allowing users to replace its source by selecting a new image file.
• fz-edit-text: Enhances a slotted HTML element, making it directly editable inline, with an optional formatting toolbar.
• fz-modal: A simple modal/dialog component.
• fz-pager: A component for paginating slotted child elements.

Getting Started

Installation

Since these are vanilla JavaScript web components, you can use them directly in your HTML files. Ensure the component's JavaScript file is imported as a module.

Example:

HTML

<script type="module" src="/path/to/fz-carousel.js"></script>
<script type="module" src="/path/to/fz-modal.js"></script>

Basic Usage

Each component is used as a custom HTML tag. Content is typically provided via slots, and behavior is configured through HTML attributes.

Example: fz-carousel

HTML

<fz-carousel loop autoplay autoplay-delay="3000" slide-gap="15px">
    <div>Slide 1</div>
    <div>Slide 2</div>
    <img src="image3.jpg" alt="Slide 3" />
</fz-carousel>

Example: fz-edit-text

HTML

<fz-edit-text toolbar persist id="editable-header">
    <h1>Edit this Header</h1>
</fz-edit-text>

Example: fz-edit-image

HTML

<fz-edit-image persist storage-key="profile-pic">
    <img src="default-avatar.png" alt="User Avatar" />
</fz-edit-image>

Refer to the JSDoc comments at the top of each component's .js file for a detailed list of attributes, properties, events, CSS custom properties, and CSS parts.

Demo

A demonstration page (index.html) is included in this repository. To view the demo:

1. Clone or download this repository.
2. Serve the index.html file using a local web server. A simple way to do this is by using a tool like live-server (available via npm: npm install -g live-server and then run live-server in the project root) or Python's built-in HTTP server (python -m http.server in the project root).
3. Open the served page in your web browser (e.g., http://localhost:8080).

The demo page showcases each component with interactive controls to modify their attributes and observe their behavior.
