const fullscreen = new FullscreenManager();

Methods:

• toggle(): void - Toggle fullscreen mode
• enter(): void - Enter fullscreen
• exit(): void - Exit fullscreen
• isInFullscreen(): boolean - Check fullscreen status

---

LoadingIndicator

Loading progress display and animations.

const indicator = new LoadingIndicator();

Methods:

• show(): void - Show loading overlay
• hide(): void - Hide loading overlay
• updateProgress(percentage: number): void - Update progress (0-100)

Setup & Configuration

Basic Setup

1. Prepare Images

   image/
   ├── 001.jpg  # First page
   ├── 002.jpg  # Second page
   └── ...      # Up to 026.jpg
   

   It can hold as many images as you'll like to use.

2. Add turn.js Dependency

   <script src="/js/turn.js"></script>

3. Customize Image URLs

   this.imageUrls = [
     "/image/001.jpg",
     "/image/002.jpg",
     // Add your images here
   ];

Advanced Configuration

Turn.js Settings (in MagazineViewer.js):

$('.flipbook').turn({
  width: 800,
  height: 600,
  autoCenter: true,
  duration: 1000,        // Animation speed
  acceleration: true,    // Hardware acceleration
  gradients: true,      // Page shadows
  elevation: 50         // 3D effect depth
});

Device-Specific Behavior:

// Customize in DeviceManager.js
if (this.deviceType === 'ios') {
  this.disableIOSBounce(); // Prevent elastic scrolling
}

Usage Examples

Basic Initialization

document.addEventListener('DOMContentLoaded', () => {
  const app = new MagazineApp();
  document.getElementById('magazine-app').appendChild(app.element);
});

Custom Event Handling

const app = new MagazineApp();

app.components.viewer.on('pageTurned', (data) => {
  console.log(`Now on page ${data.page}`);
  // Custom page change logic
});

app.components.preloader.on('progress', (data) => {
  console.log(`Loading: ${data.percentage}%`);
  // Custom progress handling
});

Programmatic Navigation

// Navigate to specific page
app.components.viewer.goToPage(5);

// Go to next page
app.components.viewer.nextPage();

// Toggle fullscreen
app.components.fullscreenManager.toggle();

Development

Adding New Components

1. Create Component

   class NewComponent extends EventEmitter {
     constructor(options) {
       super();
       this.options = options;
       this.init();
     }
     
     init() {
       // Component logic
     }
   }

2. Register in MagazineApp

   this.components = {
     // existing components...
     newComponent: new NewComponent(options)
   };

3. Set up Communication

   this.components.newComponent.on('event', (data) => {
     // Handle component events
   });

Event System

All components extend EventEmitter for consistent communication:

// Emit events
this.emit('eventName', { data: 'value' });

// Listen for events  
component.on('eventName', (data) => {
  // Handle event
});

// Remove listeners
component.off('eventName', callback);

Performance Optimization

Image Optimization

• Use progressive JPEG format
• Optimize file sizes (recommended: 200-500KB per page)
• Consider WebP format for modern browsers

Memory Management

• Images are preloaded but not cached indefinitely
• Event listeners are properly managed
• Mobile-specific optimizations included

Loading Strategy

• Progressive loading with visual feedback
• Error handling for failed image loads
• Graceful degradation on slow connections

Browser Compatibility

Fully Supported

• Chrome 60+ (Desktop/Mobile)
• Firefox 55+ (Desktop/Mobile)
• Safari 10+ (Desktop/Mobile)
• Edge 79+ (Chromium-based)

Partially Supported

• Internet Explorer 11 (limited ES6 support)
• Older mobile browsers (may need polyfills)

Troubleshooting

Common Issues

Images not loading:

• Verify image paths in MagazineApp.js
• Check web server static file serving
• Ensure proper CORS headers if serving from different domain

Turn.js not working:

• Add <script src="/js/turn.js"></script> to HTML
• Verify jQuery loads before turn.js
• Check browser console for JavaScript errors

Mobile touch issues:

• Test on actual devices, not just browser dev tools
• Verify touch event handling in NavigationControls
• Check iOS bounce prevention is working

Performance issues:

• Monitor memory usage on mobile devices
• Optimize image file sizes
• Consider reducing animation duration

Debug Mode

Enable console logging:

// Add to MagazineApp constructor
this.debug = true;

// Components will log events when debug is enabled
