Getting Started

Prerequisites

YouTube.js runs on Node.js, Deno, and modern browsers.

It requires a runtime with the following features:

  • fetch
    • On Node, we use undici's fetch implementation, which requires Node.js 16.8+. If you need to use an older version, you may provide your own fetch implementation. See providing your own fetch implementation for more information.
    • The Response object returned by fetch must thus be spec compliant and return a ReadableStream object if you want to use the VideoInfo#download method. (Implementations like node-fetch return a non-standard Readable object.)
  • EventTarget and CustomEvent are required.

Installation

# NPM
npm install youtubei.js@latest

# Yarn
yarn add youtubei.js@latest

# Git (edge version)
npm install github:LuanRT/YouTube.js
