Youtube-mp3-downloader Npm ✦ [POPULAR]

node download.js In a few moments, you’ll have a full MP3 of Rick Astley in your ./downloads folder. The default setup works, but to build a production-ready tool, you need to tweak several parameters. Custom Output File Names By default, the file is named [videoTitle].mp3 . You can override this:

YD.on("progress", (progress) => bar.update(progress.progress.percentage); );

const requestId = uuidv4(); console.log(`[$requestId] Starting download for $videoId`); youtube-mp3-downloader npm

YD.on("finished", (err, data) => bar.stop(); if (err) console.log("Error:", err); else console.log( \n✅ Saved to $data.file ); );

// Configure downloader const YD = new YoutubeMp3Downloader( outputPath: DOWNLOAD_DIR, youtubeVideoQuality: "highest", queueParallelism: 1, progressTimeout: 1000 ); node download

| Error | Cause | Solution | |-------|-------|----------| | FFmpeg not found | FFmpeg missing or not in PATH | Install FFmpeg and verify ffmpeg -version in terminal | | Video unavailable | Deleted, private, or region-blocked video | Check the URL manually; use cookies for private videos | | No audio stream | YouTube video has no audio (e.g., a static image slideshow) | Skip or notify user | | Rate limiting | Too many requests from same IP | Implement delays (e.g., setTimeout loop) or proxy rotation | | EPIPE or stream closed | Node memory limits or unstable connection | Increase memory: node --max-old-space-size=4096 script.js | async function downloadWithRetry(videoId, retries = 3) for (let i = 0; i < retries; i++) try await new Promise((resolve, reject) => YD.download(videoId); YD.once("finished", resolve); YD.once("error", reject); ); console.log("Success!"); return; catch (err) console.log(`Attempt $i+1 failed: $err.message`); if (i === retries - 1) throw err; await new Promise(r => setTimeout(r, 2000)); // wait 2 sec

Run it:

// Start download (YouTube video ID) // Example: https://www.youtube.com/watch?v=dQw4w9WgXcQ -> ID = dQw4w9WgXcQ const videoId = "dQw4w9WgXcQ"; YD.download(videoId);
