ZUI Framework ⚡

ZUI is a next-generation, lightweight abstraction layer for building native Web Components. It leverages TypeScript Stage 3 Decorators to eliminate boilerplate, manage reactive state, and streamline DOM interactions while staying close to the metal of the browser.

🚀 Why ZUI?

Standard Web Components require significant boilerplate: managing observedAttributes, manually handling shadowRoot, and verbose event dispatching. ZUI solves this with a declarative, type-safe API:

• ⚡ Stage 3 Decorators: Built for modern TypeScript, utilizing the standard accessor pattern.
• 🔄 Reactive State: Properties automatically trigger view updates and lifecycle hooks.
• 🎯 Zero-Boilerplate Refs: Type-safe DOM element caching without manual querySelector calls.
• 📡 Magic Event Emitters: Auto-generated, strictly typed event dispatch methods.
• 🎨 Scoped Styling: Seamless integration with standard Shadow DOM or scoped styles.
• 🛠 Customized Built-ins: First-class support for extending native elements (e.g., <div is="my-component">).

📦 Installation

npm install @o.z/zui
# or
yarn add @o.z/zui
# or
pnpm add @o.z/zui

🛠️ Usage Example

ZUI is designed to work seamlessly with Vite’s raw and inline string imports for templates and styles.

1. The Component (counter.ts)

import { defineElement, event, property, ref, Zui, EventEmitter } from "@o.z/zui"
import htmlStr from "./counter.html?raw"
import cssStr from "./counter.scss?inline"

export type CounterClickEvent = { count: number; e?: MouseEvent }

@defineElement({
  tagName: "my-counter",
  html: htmlStr,
  css: cssStr,
  options: { extends: 'div' } // Extend native div functionality
})
export class Counter extends Zui(HTMLDivElement) {
  // 1. Reactive State: Synchronized with 'count' attribute
  @property()
  accessor count = 0

  // 2. DOM References: Automatically queried from Shadow Root
  @ref(".counter-display")
  displayRef!: HTMLDivElement

  @ref(".btn-inc")
  incBtn!: HTMLButtonElement

  // 3. Event Emitter: Typed event dispatcher
  @event()
  counterClick!: EventEmitter<CounterClickEvent>

  connected() {
    this.incBtn.addEventListener("click", () => {
        this.counterClick.emit({ count: 1 })
    })
  }

  // 4. Reactive Hook: Called when 'count' changes
  countUpdate(oldValue: number, newValue: number) {
    this.displayRef.innerHTML = newValue.toString()
  }
}

2. Usage in HTML

Since we extended the native div, we use the is attribute:

<div id="counter" is="my-counter">
  <span slot="increase">Increment</span>
</div>

<script type="module">
  import { Counter } from "./counter"
  
  const el = document.querySelector("#counter")
  
  // Fully typed event details via e.detail.value
  el.addEventListener("counter-click", (e) => {
    el.count += e.detail.value.count
  })
</script>
