Warning:

We're currently in the process of rewriting some parts of the library to improve performance, maintainability and quality. While this might take a little while, most of this documentation will no longer be valid after v2 (see #65).

Live chats:


Currently, the library can retrieve the live chat, stats, and send messages.

Example:

import Innertube from 'youtubei.js';

const youtube = await new Innertube();

const search = await youtube.search('Lofi girl live');
const video = await youtube.getDetails(search.videos[0].id);
  
const livechat = video.getLivechat();

// Updated stats about the livestream
livechat.on('update-metadata', (data) => {
  console.info('Info:', data);
});
   
// Fired whenever there is a new message or other chat events
livechat.on('chat-update', (message) => {
  console.info(`- ${message.author.name}\n${message.text}\n\n`);
    
  if(message.text == '!info') {
    livechat.sendMessage('Hello! This message was sent from YouTube.js');
  }
});

Stop fetching the live chat:

livechat.stop();

Delete a message:

const msg = await livechat.sendMessage('Nice livestream!');
await msg.deleteMessage();

Downloading videos:


const options = {
  format?: string,
  quality?: string,
  type?: string,
  range?: { start: number, end: number }
};

const stream = youtube.download('VIDEO_ID', options);

Options:

  • format: mp4 | webm etc.. (note: only formats provided by YouTube are available)

  • quality: 144p, 240p, 360p, 480p, 720p, 1080p etc..

  • type: video | audio | videoandaudio

  • range: indicates which bytes should be downloaded

    • start: an integer indicating the beginning of the range
    • end: an integer indicating the end of the range

Cancel a download:

stream.cancel();

Example:

import fs from 'fs';
import Innertube from 'youtubei.js';

const youtube = await new Innertube();
const search = await youtube.search('Sound Coming From A Massive Black Hole - Anton Petrov');
  
const stream = youtube.download(search.videos[0].id, {
  format: 'mp4', // defaults to mp4
  quality: '720p', // falls back to 360p if a specific quality isn't available
  type: 'videoandaudio' 
});
  
stream.pipe(fs.createWriteStream(`./${search.videos[0].id}.mp4`));
 
stream.on('start', () => {
  console.info('[YOUTUBE.JS]', 'Starting now!');
});
  
stream.on('info', (info) => {
  console.info('[YOUTUBE.JS]', `Downloading ${info.video_details.title} by ${info.video_details.metadata.channel_name}`);
});
  
stream.on('progress', (info) => {
  process.stdout.clearLine();
  process.stdout.cursorTo(0);
  process.stdout.write(`[YOUTUBE.JS] Downloaded ${info.percentage}% (${info.downloaded_size}MB) of ${info.size}MB`);
});
  
stream.on('end', () => {
  process.stdout.clearLine();
  process.stdout.cursorTo(0);
  console.info('[YOUTUBE.JS]', 'Done!');
});
  
stream.on('error', (err) => console.error('[ERROR]', err)); 

Alternatively, you can get the deciphered streaming data and handle the download yourself:

await youtube.getStreamingData('VIDEO_ID', options);
Output

{
  selected_format: {
    itag: number,
    mimeType: string,
    bitrate: number,
    initRange: { start: string, end: string },
    indexRange: { start: string, end: string },
    lastModified: string,
    contentLength: string,
    quality: string,
    projectionType: string,
    averageBitrate: number,
    highReplication: boolean,
    audioQuality: string,
    approxDurationMs: string,
    audioSampleRate: string,
    audioChannels: number,
    loudnessDb: number,
    url: string,
    has_audio: boolean,
    has_video: boolean
  },
  formats: [
    {
      itag: number,
      mimeType: string,
      bitrate: number,
      initRange: { start: string, end: string },
      indexRange: { start: string, end: string },
      lastModified: string,
      contentLength: string,
      quality: string,

      averageBitrate: number,
      highReplication: boolean,
      audioQuality: string,
      approxDurationMs: string,
      audioSampleRate: string,
      audioChannels: number,
      loudnessDb: number,
      url: string,
      has_audio: boolean,
      has_video: boolean
    }
  ]
}
  

Signing in:


When signing in to a Google account, you have two options:

  • OAuth 2.0; easy, simple & reliable.
  • Cookies; usually complicated to extract and unreliable.

OAuth:

import fs from 'fs';
import Innertube from 'youtubei.js';

const youtube = await new Innertube();

const creds_path = './yt_oauth_creds.json'; 
const creds = fs.existsSync(creds_path) && JSON.parse(fs.readFileSync(creds_path).toString()) || {};

youtube.ev.on('auth', (data) => {
  switch (data.status) {
    case 'AUTHORIZATION_PENDING':
      console.info(`
        Hello! On your phone or computer,
        go to ${data.verification_url} and enter
        the code ${data.code}.
      `);
      break;
    case 'SUCCESS':
      fs.writeFileSync(creds_path, JSON.stringify(data.credentials));
      console.info('Successfully signed in, enjoy!');
      break;
  }
});

youtube.ev.on('update-credentials', (data) => {
  fs.writeFileSync(creds_path, JSON.stringify(data.credentials));
