```

## Quick Start

### 1. Create Your Component

```typescript
import { DeesElement, customElement, html, css, property } from '@design.estate/dees-element';

@customElement('my-button')
export class MyButton extends DeesElement {
  // Define a demo for the catalogue
  public static demo = () => html`
    <my-button .label=${'Click me!'} .variant=${'primary'}></my-button>
  `;

  @property({ type: String })
  accessor label: string = 'Button';

  @property({ type: String })
  accessor variant: 'primary' | 'secondary' = 'primary';

  public static styles = [
    css`
      :host {
        display: inline-block;
      }
      button {
        padding: 8px 16px;
        border-radius: 4px;
        border: none;
        font-size: 14px;
        cursor: pointer;
        transition: all 0.3s;
      }
      button.primary {
        background: #007bff;
        color: white;
      }
      button.secondary {
        background: #6c757d;
        color: white;
      }
      button:hover {
        opacity: 0.9;
      }
    `
  ];

  public render() {
    return html`
      <button class="${this.variant}">
        ${this.label}
      </button>
    `;
  }
}
```

### 2. Set Up Your Catalogue

```typescript
// catalogue.ts
import { setupWccTools } from '@design.estate/dees-wcctools';
import { html } from 'lit';

// Import your components
import { MyButton } from './components/my-button.js';
import { MyCard } from './components/my-card.js';

// Define elements for the catalogue
const elements = {
  'my-button': MyButton,
  'my-card': MyCard,
};

// Optionally define pages
const pages = {
  'home': () => html`
    <div style="padding: 20px;">
      <h1>Welcome to My Component Library</h1>
      <p>Browse components using the sidebar.</p>
    </div>
  `,
  'getting-started': () => html`
    <div style="padding: 20px;">
      <h2>Getting Started</h2>
      <p>Installation and usage instructions...</p>
    </div>
  `,
};

// Initialize the catalogue
setupWccTools(elements, pages);
```

### 3. Create an HTML Entry Point

```html
<!DOCTYPE html>
<html>
<head>
  <title>Component Catalogue</title>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body style="margin: 0; padding: 0;">
  <script type="module" src="./catalogue.js"></script>
</body>
</html>
```

## Features

### 🎯 Live Property Editing

The properties panel automatically detects and allows editing of:

| Property Type | Editor |
|--------------|--------|
| **String** | Text input |
| **Number** | Number input |
| **Boolean** | Checkbox |
| **Enum** | Select dropdown |
| **Object/Array** | JSON editor modal |

### 📱 Viewport Testing

Test your components across different screen sizes:

- **Phone** — 320px width
- **Phablet** — 600px width
- **Tablet** — 768px width
- **Desktop** — Full width (native)

### 🌓 Theme Support

Components automatically adapt to light/dark themes using the `goBright` property:

```typescript
public render() {
  return html`
    <div class="${this.goBright ? 'light-theme' : 'dark-theme'}">
      <!-- Your component content -->
    </div>
  `;
}
```

Or use CSS custom properties with the theme manager:

```typescript
import { cssManager } from '@design.estate/dees-element';

public static styles = [
  css`
    :host {
      color: ${cssManager.bdTheme('#000', '#fff')};
      background: ${cssManager.bdTheme('#fff', '#000')};
    }
  `
];
```

### 🎬 Screen Recording

Record component demos directly from the catalogue! The built-in recorder supports:

- **Viewport Recording** — Record just the component viewport
- **Full Screen Recording** — Capture the entire screen
- **Audio Support** — Add microphone commentary with live level monitoring
- **Video Trimming** — Trim start/end before export with visual timeline
- **WebM Export** — High-quality video output

Click the red record button in the bottom toolbar to start.

### 🧪 Demo Tools

The demotools module provides enhanced testing capabilities with `dees-demowrapper`:

```typescript
import '@design.estate/dees-wcctools/demotools';

@customElement('my-component')
export class MyComponent extends DeesElement {
  public static demo = () => html`
    <dees-demowrapper .runAfterRender=${async (wrapper) => {
      // Find elements using standard DOM APIs
      const myComponent = wrapper.querySelector('my-component');

      // Simulate user interactions
      myComponent.value = 'Test value';
      await myComponent.updateComplete;

      // Work with multiple elements
      wrapper.querySelectorAll('.item').forEach((el, i) => {
        console.log(`Item ${i}:`, el.textContent);
      });
    }}>
      <my-component></my-component>
      <div class="item">Item 1</div>
      <div class="item">Item 2</div>
    </dees-demowrapper>
  `;
}
```

### ⏳ Async Demos

Return a `Promise` from `demo` for async setup. The dashboard waits for resolution:

```typescript
public static demo = async () => {
  const data = await fetchSomeData();
  return html`<my-component .data=${data}></my-component>`;
};
```

### 🎭 Container Queries

Components can respond to their container size using the `wccToolsViewport` container:

```typescript
public static styles = [
  css`
    @container wccToolsViewport (min-width: 768px) {
      :host {
        flex-direction: row;
      }
    }

    @container wccToolsViewport (max-width: 767px) {
      :host {
        flex-direction: column;
      }
    }
  `
];
```

## Component Guidelines

### Required for Catalogue Display

1. Components must expose a static `demo` property returning a Lit template
2. Use `@property()` decorators with the `accessor` keyword for editable properties
3. Export component classes for proper detection

### Best Practices

```typescript
@customElement('best-practice-component')
export class BestPracticeComponent extends DeesElement {
  // ✅ Static demo property
  public static demo = () => html`
    <best-practice-component
      .complexProp=${{ key: 'value' }}
      simpleAttribute="test"
    ></best-practice-component>
  `;

  // ✅ Typed properties with defaults (TC39 decorators)
  @property({ type: String })
  accessor title: string = 'Default Title';

  // ✅ Complex property without attribute
  @property({ attribute: false })
  accessor complexProp: { key: string } = { key: 'default' };

  // ✅ Enum with proper typing
  @property({ type: String })
  accessor variant: 'small' | 'medium' | 'large' = 'medium';
}
```

## URL Routing

The catalogue uses URL routing for deep linking:

```
/wcctools-route/:type/:name/:viewport/:theme

Examples:
/wcctools-route/element/my-button/desktop/dark
/wcctools-route/page/home/tablet/bright
```

## API Reference

### `setupWccTools(elements, pages?)`

Initialize the WCC Tools dashboard.

| Parameter | Type | Description |
|-----------|------|-------------|
| `elements` | `Record<string, typeof LitElement>` | Map of element names to classes |
| `pages` | `Record<string, TTemplateFactory>` | Optional map of page names to template functions |

### `DeesDemoWrapper`

Component for wrapping demos with post-render logic.

| Property | Type | Description |
|----------|------|-------------|
| `runAfterRender` | `(wrapper) => void \| Promise<void>` | Callback after wrapped elements render |

The wrapper provides full DOM API access:
- `wrapper.querySelector()` — Find single element
- `wrapper.querySelectorAll()` — Find multiple elements
- `wrapper.children` — Access child elements directly

### Recording Components (Advanced)

For custom recording integrations:

```typescript
import { RecorderService } from '@design.estate/dees-wcctools';

const recorder = new RecorderService({
  onDurationUpdate: (duration) => console.log(`${duration}s`),
  onRecordingComplete: (blob) => console.log('Recording done!', blob),
  onAudioLevelUpdate: (level) => console.log(`Audio: ${level}%`),
});

await recorder.startRecording({ mode: 'viewport' });
// ... later
recorder.stopRecording();
```
