youtubei.js
Advanced tools
A full-featured library that allows you to get detailed info about any video, subscribe, unsubscribe, like, dislike, comment, search, download videos/music and much more!
A full-featured wrapper around the Innertube API, which is what YouTube itself uses.
Innertube is an API used across all YouTube clients, it was made to simplify the internal structure of the platform and make it easy to push updates. This library takes advantage of that API, therefore providing a simple & efficient way to interact with YouTube programmatically.
And big thanks to @gatecrasher777 for his research on the workings of the Innertube API!
As of now, this is one of the most advanced & stable YouTube libraries out there, here's a short summary of its features:
Do note that you must be signed-in to perform actions that involve an account, such as commenting, subscribing, sending messages to a live chat, etc.
No, YouTube.js does not use any official API so no API keys are required.
NodeJS v14 or greater
To verify things are set up properly, you can run this:
node --version
npm install youtubei.js@latest
yarn add youtubei.js@latest
First of all we're gonna start by initializing the Innertube instance. And to make things faster, you should do this only once and reuse the Innertube object when needed.
const Innertube = require('youtubei.js');
const youtube = await new Innertube();
YouTube:
const search = await youtube.search('Looking for life on Mars - Documentary');
YTMusic:
const search = await youtube.search('Interstellar Main Theme', { client: 'YTMUSIC' });

The library makes it easy to interact with YouTube programmatically. However, don't forget that you must be signed in to use the following features!
Subscribe/Unsubscribe:
await youtube.interact.subscribe('CHANNEL_ID');
await youtube.interact.unsubscribe('CHANNEL_ID');
Like/Dislike:
await youtube.interact.like('VIDEO_ID');
await youtube.interact.dislike('VIDEO_ID');
await youtube.interact.removeLike('VIDEO_ID');
Comment:
await youtube.interact.comment('VIDEO_ID', 'Haha, nice video!');
Change notification preferences:
// Options: ALL | NONE | PERSONALIZED
await youtube.interact.changeNotificationPreferences('CHANNEL_ID', 'ALL');
These methods will always return { success: true, status_code: 200 } if successful.
It is also possible to manage an account's settings:
Get account info:
await youtube.account.info();
{
name: string,
photo: [
{
url: string,
width: number,
height: number
}
],
country: string,
language: string;
}
Subscription notifications:
await youtube.account.settings.notifications.setSubscriptions(true);
Recommended content notifications:
await youtube.account.settings.notifications.setRecommendedVideos(true);
Channel activity notifications:
await youtube.account.settings.notifications.setChannelActivity(true);
Comment replies notifications:
await youtube.account.settings.notifications.setCommentReplies(true);
Channel mention notifications:
await youtube.account.settings.notifications.setSharedContent(true);
Subscriptions privacy:
await youtube.account.settings.privacy.setSubscriptionsPrivate(true);
Saved playlists privacy:
await youtube.account.settings.privacy.setSavedPlaylistsPrivate(true);
YouTube.js isn't able to download live content yet, but it does allow you to fetch live chats plus you can also send messages!
const Innertube = require('youtubei.js');
async function start() {
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');
}
});
}
start();
Stop fetching the live chat:
livechat.stop();
Delete a message:
const msg = await livechat.sendMessage('Nice livestream!');
await msg.deleteMessage();
YouTube.js provides an easy-to-use and simple downloader:
const fs = require('fs');
const Innertube = require('youtubei.js');
async function start() {
const youtube = await new Innertube();
const search = await youtube.search('Looking for life on Mars - documentary');
const stream = youtube.download(search.videos[0].id, {
format: 'mp4', // Optional, defaults to mp4 and I recommend to leave it as it is unless you know what you're doing
quality: '360p', // if a video doesn't have a specific quality it'll fall back to 360p, also ignored when type is set to audio
type: 'videoandaudio' // can be “video”, “audio” and “videoandaudio”
});
stream.pipe(fs.createWriteStream(`./${search.videos[0].title}.mp4`));
stream.on('start', () => {
console.info('[DOWNLOADER]', 'Starting download now!');
});
stream.on('info', (info) => {
// { video_details: {..}, selected_format: {..}, formats: {..} }
console.info('[DOWNLOADER]', `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(`[DOWNLOADER] Downloaded ${info.percentage}% (${info.downloaded_size}MB) of ${info.size}MB`);
});
stream.on('end', () => {
process.stdout.clearLine();
process.stdout.cursorTo(0);
console.info('[DOWNLOADER]', 'Done!');
});
stream.on('error', (err) => console.error('[ERROR]', err));
}
start();
You can also specify a range:
const stream = youtube.download(VIDEO_ID, {
//...
type: 'videoandaudio',
range: { start: 0, end: 1048576 * 5 }
});
Cancel a download:
stream.cancel();
Alternatively, you can get the deciphered streaming data and handle the download yourself:
const streaming_data = await youtube.getStreamingData(search.videos[0].id, {
format: 'mp4',
quality: '360p',
type: 'videoandaudio'
});
{
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,

}
When signing in to your account, you have two options:
const fs = require('fs');
const Innertube = require('youtubei.js');
const creds_path = './yt_oauth_creds.json';
async function start() {
const creds = fs.existsSync(creds_path) && JSON.parse(fs.readFileSync(creds_path).toString()) || {};
const youtube = await new Innertube();
youtube.ev.on('auth', (data) => {
if (data.status === 'AUTHORIZATION_PENDING') {
console.info(`Hello!\nOn your phone or computer, go to ${data.verification_url} and enter the code ${data.code}`);
} else if (data.status === 'SUCCESS') {
fs.writeFileSync(creds_path, JSON.stringify(data.credentials));
console.info('Successfully signed-in, enjoy!');
}
});
youtube.ev.on('update-credentials', (data) => {
fs.writeFileSync(creds_path, JSON.stringify(data.credentials));
console.info('Credentials updated!', data);
});
await youtube.signIn(creds);
//...
}
start();
const Innertube = require('youtubei.js');
async function start() {
const youtube = await new Innertube(COOKIE_HERE);
//...
}
start();
