Installation

npm install ytdlp-nodejs

Note: FFmpeg is recommended for full functionality. Install it manually or use the built-in downloadFFmpeg() method.

Quick Start

import { YtDlp } from 'ytdlp-nodejs';

const ytdlp = new YtDlp();

// Download a video with fluent API
const result = await ytdlp
  .download('https://youtube.com/watch?v=dQw4w9WgXcQ')
  .filter('mergevideo')
  .quality('1080p')
  .type('mp4')
  .on('progress', (p) => console.log(`${p.percentage_str}`))
  .run();

console.log('Downloaded:', result.filePaths);

// Get video info
const info = await ytdlp.getInfoAsync(
  'https://youtube.com/watch?v=dQw4w9WgXcQ',
);
console.log(info.title);

// Stream to file
import { createWriteStream } from 'fs';
const stream = ytdlp.stream('https://youtube.com/watch?v=dQw4w9WgXcQ');
await stream.pipeAsync(createWriteStream('video.mp4'));

CLI Usage

Interactive Mode

Launch the interactive menu to access all features with guided prompts:

ytdlp

Direct Commands

These commands run without prompts:

# List available formats
ytdlp formats <url>

# Download with specific quality (non-interactive)
ytdlp video <url> --quality 1080p

# Download FFmpeg binaries
ytdlp ffmpeg

# Update yt-dlp binary
ytdlp update

API Reference

Constructor

const ytdlp = new YtDlp({
  binaryPath?: string,  // Path to yt-dlp binary
  ffmpegPath?: string,  // Path to ffmpeg binary
});

Download Methods

download(url, options?)

Returns a fluent builder for downloading with chainable methods.

// Fluent builder API (recommended)
const result = await ytdlp
  .download('https://youtube.com/watch?v=...')
  .format({ filter: 'mergevideo', quality: '1080p', type: 'mp4' })
  .output('./downloads')
  .embedThumbnail()
  .on('progress', (p) => console.log(`${p.percentage_str}`))
  .run();

console.log('Files:', result.filePaths);

// With initial options
const result = await ytdlp
  .download(url, {
    format: { filter: 'mergevideo', quality: '1080p', type: 'mp4' },
  })
  .embedThumbnail()
  .on('progress', (p) => console.log(p))
  .run();

Events	.on('start' | 'progress' | 'beforeDownload' | 'stdout' | 'stderr' | 'error' | 'finish', fn)
Execute	.run() - returns Promise<DownloadFinishResult> - Also directly awaitable

downloadAsync(url, options?)

Downloads a video asynchronously with callback-style progress.

const result = await ytdlp.downloadAsync(url, {
  format: { filter: 'mergevideo', type: 'mp4', quality: '1080p' },
  output: './downloads/%(title)s.%(ext)s',
  onProgress: (progress) => console.log(progress),
});

downloadAudio(url, format?, options?)

Downloads audio only.

await ytdlp.downloadAudio(url, 'mp3'); // 'aac', 'flac', 'mp3', 'm4a', 'opus', 'vorbis', 'wav', 'alac'

downloadVideo(url, quality?, options?)

Downloads video with specific quality.

await ytdlp.downloadVideo(url, '1080p'); // 'best', '2160p', '1440p', '1080p', '720p', etc.

Streaming

stream(url, options?)

Returns a fluent builder for streaming with chainable methods.

import { createWriteStream } from 'fs';

// Fluent builder API
const result = await ytdlp
  .stream('https://youtube.com/watch?v=...')
  .filter('audioandvideo')
  .quality('highest')
  .type('mp4')
  .on('progress', (p) => console.log(p.percentage_str))
  .pipeAsync(createWriteStream('video.mp4'));

console.log(`Bytes: ${result.bytes}`);

// Sync pipe
ytdlp.stream(url).filter('audioandvideo').pipe(writableStream);

// Stream to buffer
const buffer = await ytdlp.stream(url).filter('audioonly').toBuffer();

Stream Builder Methods

Method	Description
.filter(), .quality(), .type()	Set format options (same as Download)
.pipe(dest, options?)	Pipe to writable stream, returns Promise

.getStream()	Get underlying PassThrough stream
.on('start' | 'progress' | 'beforeDownload' | 'data' | 'error' | 'end', fn)	Event listeners

getFileAsync(url, options?)

Returns a File object without saving to disk.

const file = await ytdlp.getFileAsync(url, {
  format: { filter: 'audioonly', type: 'mp3' },
  onProgress: (p) => console.log(p),
});
console.log(file.name, file.size);

Information Methods

const info = await ytdlp.getInfoAsync(url);
console.log(info.title, info.duration, info.formats);

const title = await ytdlp.getTitleAsync(url);

getThumbnailsAsync(url)

const thumbnails = await ytdlp.getThumbnailsAsync(url);

getVersionAsync()

const version = await ytdlp.getVersionAsync();

Utility Methods

checkInstallationAsync(options?)

const installed = await ytdlp.checkInstallationAsync({ ffmpeg: true });

downloadFFmpeg()

await ytdlp.downloadFFmpeg();

updateYtDlpAsync(options?)

const result = await ytdlp.updateYtDlpAsync();
console.log(`Updated to ${result.version}`);

Format Options

Use structured format options for type-safe configuration:

// Video only
{ filter: 'videoonly', type: 'mp4', quality: '1080p' }

// Audio only
{ filter: 'audioonly', type: 'mp3', quality: 5 }

// Audio and video (single file)
{ filter: 'audioandvideo', type: 'mp4', quality: 'highest' }

// Merge video and audio
{ filter: 'mergevideo', type: 'mp4', quality: '1080p' }

Quality Options

Filter	Quality Values
videoonly, mergevideo	'2160p', '1440p', '1080p', '720p', '480p', '360p', '240p', '144p', 'highest', 'lowest'
audioandvideo	'highest', 'lowest'
audioonly	0 to 10 (VBR quality)

Type Options

Filter	Type Values
videoonly, audioandvideo	'mp4', 'webm'
audioonly	'aac', 'flac', 'mp3', 'm4a', 'opus', 'vorbis', 'wav', 'alac'
mergevideo	'mkv', 'mp4', 'ogg', 'webm', 'flv'

Advanced Options

JavaScript Runtime

Node.js is used as the default JavaScript runtime for yt-dlp extractors:

await ytdlp.execAsync(url, {
  jsRuntime: 'node', // default, or 'deno', 'phantomjs'
});

Raw Arguments

Pass any yt-dlp argument directly:

await ytdlp.downloadAsync(url, {
  rawArgs: ['--match-filter', 'duration > 60', '--geo-bypass'],
});

Debug Mode

await ytdlp.execAsync(url, {
  debugPrintCommandLine: true,
  verbose: true,
});

Troubleshooting

Binary not found

import { helpers } from 'ytdlp-nodejs';
await helpers.downloadYtDlp();
await helpers.downloadFFmpeg();

Or provide custom paths:

const ytdlp = new YtDlp({
  binaryPath: '/path/to/yt-dlp',
  ffmpegPath: '/path/to/ffmpeg',
});
