🚀 Quick Start

1. Basic Setup

<!DOCTYPE html>
<html>
<head>
    <title>Your App</title>
</head>
<body>
    <!-- Your content here -->
    
    <!-- Load CDN loader -->
    <script src="main.js"></script>
    
    <!-- Auto-load libraries -->
    <script>
        // Load Bootstrap + AOS automatically
        loadCDN();
    </script>
</body>
</html>

2. Advanced Usage

// Configure untuk optimal performance
configureCDN({
    parallelLoading: true,  // Load parallel (default: true)
    useCache: true,         // Enable caching (default: true)
    timeout: 10000,         // Timeout 10 detik
    retryAttempts: 3,       // Retry 3x jika gagal
    logLevel: 'info'        // Log level: silent/error/warn/info/debug
});

// Load specific libraries
await loadCDN(['bootstrap']);           // Bootstrap only
await loadCDN(['aos']);                // AOS only
await loadCDN(['bootstrap', 'aos']);   // Both libraries

// Load dengan options
await loadCDN(['bootstrap'], {
    logLevel: 'debug',
    parallelLoading: false
});

🔧 API Reference

Core Functions

`loadCDN(libraries, options)`

// Load libraries dengan configuration
const result = await loadCDN(['bootstrap', 'aos'], {
    parallelLoading: true,
    useCache: true,
    logLevel: 'info'
});

console.log(result);
// {
//   totalTime: 850,
//   successful: 2,
//   failed: 0,
//   results: [...]
// }

`configureCDN(options)`

configureCDN({
    timeout: 15000,         // Loading timeout
    retryAttempts: 5,       // Retry attempts
    parallelLoading: true,  // Parallel vs sequential
    useCache: true,         // Enable caching
    logLevel: 'debug'       // Log verbosity
});

`addCustomLibrary(name, config)`

// Add custom library
addCustomLibrary('animate', {
    css: 'https://cdnjs.cloudflare.com/ajax/libs/animate.css/4.1.1/animate.min.css',
    js: null, // CSS-only library
    init: () => {
        // Custom initialization code
        console.log('Animate.css loaded!');
    }
});

// Load custom library
await loadCDN(['animate']);

`getCDNStats()`

const stats = getCDNStats();
console.log(stats);
// {
//   cached: 4,      // Cached items
//   loading: 0,     // Currently loading
//   libraries: 6    // Available libraries
// }

`clearCDNCache()`

// Clear all cache
clearCDNCache();

📚 Built-in Libraries

Bootstrap 5.3.3

await loadCDN(['bootstrap']);
// Includes: CSS + JS bundle with integrity checking

AOS (Animate On Scroll) 2.3.1

await loadCDN(['aos']);
// Auto-initialized with optimal settings:
// - duration: 800ms
// - easing: ease-out-cubic
// - once: true (animate only once)
// - offset: 50px

SweetAlert2 (Example custom)

addCustomLibrary('sweetalert', {
    css: 'https://cdn.jsdelivr.net/npm/sweetalert2@11/dist/sweetalert2.min.css',
    js: 'https://cdn.jsdelivr.net/npm/sweetalert2@11/dist/sweetalert2.all.min.js'
});

await loadCDN(['sweetalert']);

🎯 Quick Functions

Quick Load Options

// Quick functions for common use cases
quickBootstrap();  // Load Bootstrap only
quickAOS();        // Load AOS only  
quickAll();        // Load Bootstrap + AOS

⚡ Performance Features

1. Parallel Loading

// Libraries loaded simultaneously, bukan sequential
await loadCDN(['bootstrap', 'aos', 'sweetalert']); // Semua parallel!

2. Smart Caching

// First load: ~2000ms (download from CDN)
await loadCDN(['bootstrap']);

// Second load: ~50ms (from cache)
await loadCDN(['bootstrap']); // Cache hit!

3. Resource Preloading

// Resources di-preload dengan optimal attributes
// - async/defer untuk scripts
// - crossOrigin untuk security
// - integrity untuk verification

4. Error Recovery

// Auto-retry dengan exponential backoff
// Timeout protection
// Fallback error handling

🛠️ Development Features

1. Debug Mode

configureCDN({ logLevel: 'debug' });
// Akan show detailed loading info:
// 🐛 Cache hit: bootstrap-css
// 🐛 Loading: aos-js  
// 🐛 ✅ Loaded: aos-js in 245ms

2. Performance Monitoring

const result = await loadCDN(['bootstrap']);
console.log(`Libraries loaded in ${result.totalTime}ms`);

3. Error Handling

try {
    await loadCDN(['bootstrap']);
} catch (error) {
    console.error('Loading failed:', error);
    // Handle gracefully
}

🎮 Demo & Testing

✅ Mobile browsers (iOS Safari, Chrome Mobile)

🎯 Best Practices

1. Optimal Configuration

// Recommended untuk production
configureCDN({
    parallelLoading: true,
    useCache: true,
    timeout: 8000,
    retryAttempts: 3,
    logLevel: 'warn' // Atau 'silent' untuk production
});

2. Error Handling

// Always handle loading errors gracefully
try {
    await loadCDN(['bootstrap', 'aos']);
    // Initialize your app
    initializeApp();
} catch (error) {
    // Fallback atau retry logic
    console.warn('Some libraries failed to load, using fallbacks');
    initializeAppWithFallbacks();
}

3. Performance Tips

// Load libraries as early as possible
document.addEventListener('DOMContentLoaded', () => {
    loadCDN(['bootstrap', 'aos']); // Start loading immediately
});

// Atau preload di head
<link rel="preload" href="./scripts/callLibrary.js" as="script">
