Inside the downloadMp3 function, use ytdl-core to download the YouTube video:
Create a new file called index.js in your project directory. This will be the main script for our YouTube MP3 downloader. youtube-mp3-downloader npm
ytdl(url, { filter: 'audioonly' }) .pipe(ffmpeg({ // ... })) .on('progress', (progress) => { console.log(`Downloading ${progress.percent}%`); }) .on('end', () => { console.log('Download complete!'); }) .on('error', (err) => { console.error(err); }); Here, we’re using ytdl-core to download the audio-only stream of the YouTube video. We’re then piping the output to fluent-ffmpeg , which will handle the audio processing. Inside the downloadMp3 function, use ytdl-core to download
const ytdl = require('ytdl-core'); const ffmpeg = require('fluent-ffmpeg'); const fs = require('fs'); Inside the downloadMp3 function
npm install ytdl-core fluent-ffmpeg
