Error Handling and Fallbacks

async function handleVideoProcessing(url) { try { showLoader(); // Try primary method let result = await primaryProcessingMethod(url); if (!result) { // Fallback to secondary method result = await secondaryProcessingMethod(url); } if (!result) { throw new Error('Unable to process this video'); } displayResults(result); } catch (error) { showError(error.message); // Suggest alternative solutions if (error.message.includes('private video')) { showAlternativeSolutions('private'); } else if (error.message.includes('age restricted')) { showAlternativeSolutions('age-restricted'); } } finally { hideLoader(); } }

Progress Tracking

// Using EventSource for progress updates function trackProgress(downloadId) { const eventSource = new EventSource(`/progress/${downloadId}`); eventSource.onmessage = (event) => { const progress = JSON.parse(event.data); updateProgressBar(progress.percentage); if (progress.status === 'completed') { eventSource.close(); enableDownload(progress.downloadUrl); } }; eventSource.onerror = () => { showError('Progress tracking failed'); eventSource.close(); }; }

Platform-Specific Processing

async function processYouTubeVideo(url) { // Extract video ID const videoId = url.match(/(?:youtube\.com\/(?:[^\/]+\/.+\/|(?:v|e(?:mbed)?)\/|.*[?&]v=)|youtu\.be\/)([^"&?\/\s]{11})/i)[1]; // Use YouTube API or yt-dlp const response = await fetch(`https://your-backend.com/youtube?videoId=${videoId}`); const data = await response.json(); return { title: data.title, thumbnail: data.thumbnails.maxres?.url || data.thumbnails.standard?.url, formats: data.formats.map(format => ({ quality: format.qualityLabel, type: format.mimeType.split(';')[0].split('/')[1], size: format.contentLength ? (format.contentLength / (1024 * 1024)).toFixed(1) + 'MB' : 'Unknown', url: format.url })) }; }
