Youtube-mp3-downloader Npm May 2026

Downloading videos from YouTube generally violates YouTube's Terms of Service (ToS), specifically Section 3, which states: "You shall not download any Content unless you see a 'download' or similar link displayed by YouTube on the Service for that Content."

const YouTubeMp3Downloader = require("youtube-mp3-downloader");
// Configure downloader
const YD = new YouTubeMp3Downloader(
ffmpegPath: "/usr/bin/ffmpeg",        // Path to ffmpeg
outputPath: "./downloads",            // Where to save MP3s
youtubeVideoQuality: "highestaudio", // highestaudio, lowestaudio
queueParallelism: 2,                 // parallel downloads
progressTimeout: 2000                // progress event interval (ms)
);
// Download video by ID (extract from YouTube URL)
const videoId = "dQw4w9WgXcQ"; // example
YD.download(videoId, $videoId.mp3);
YD.on("finished", (err, data) => 
console.log(✅ Downloaded: $data.file);
);
YD.on("error", (error) => 
console.error("❌ Error:", error);
);
YD.on("progress", (progress) => 
console.log($progress.progress.percentage% downloaded);
);

Before you write a single line of JavaScript, you need to set up your environment.

Create a file download.js:

const YouTubeMp3Downloader = require("youtube-mp3-downloader");
const readline = require("readline");
const rl = readline.createInterface(
input: process.stdin,
output: process.stdout
);
rl.question("YouTube URL: ", (url) => 
const videoId = extractId(url);
if (!videoId) 
console.log("Invalid URL");
process.exit(1);

const downloader = new YouTubeMp3Downloader( "ffmpeg",
outputPath: "./mp3s",
queueParallelism: 1
); Before you write a single line of JavaScript,
downloader.download(videoId, $videoId.mp3);
downloader.on("progress", (p) => 
process.stdout.write(\r⏳ $p.progress.percentage.toFixed(1)%);
);
downloader.on("finished", () => 
console.log("\n✅ Done!");
process.exit();
);
downloader.on("error", (e) => 
console.error("\n❌", e);
process.exit(1);
);
);
function extractId(url) /\d/
