ytmusicapiJS: Unofficial API for YouTube Music

ytmusicapiJS is a TypeScript implementation of the Python 3 library ytmusicapi for NodeJS

It emulates YouTube Music web client requests using the user's cookie data for authentication.

This library is intended to carry the same functionality as the library it is inspired by. As such, unless the need becomes great enough for a specific feature in this library, I recommend all API specific changes be directed to ytmusicapi instead.

Features

See API here https://codyduong.github.io/ytmusicapiJS/

Setup and Usage

npm yarn
npm install @codyduong/ytmusicapi yarn add @codyduong/ytmusicapi

For authenticated requests

To run authenticated requests you need to set up you need to copy your request headers from a POST request in your browser. To do so, follow these steps:

  • Open a new tab
  • Open the developer tools (Ctrl-Shift-I) and select the “Network” tab
  • Go to https://music.youtube.com and ensure you are logged in
  • Find an authenticated POST request. The simplest way is to filter by /browse using the search bar of the developer tools. If you don’t see the request, try scrolling down a bit or clicking on the library button in the top bar.

A sample headers.json is provided below:

{
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0",
    "Accept": "*/*",
    "Accept-Language": "en-US,en;q=0.5",
    "Content-Type": "application/json",
    "X-Goog-AuthUser": "0",
    "x-origin": "https://music.youtube.com",
    "Cookie" : "PASTE_COOKIE"
}

Either point to this file when instantiating YTMusic, or load the file with JSON.parse ahead of time and pass in the object.

const ytm = new YTMusic({auth: 'path/to/headers.json'})
const ytm = new YTMusic({auth: JSON.parse('path/to/headers.json')}
// Or even a raw string object is accepted
const ytm = new YTMusic({auth: fs.readFileSync('path/to/file', {encoding: 'utf-8'})}

Quick Usage

Quick Usage Snippet

import YTMusic from '@codyduong/ytmusicapi';

const ytm = new YTMusic()

const results = await ytm.search('Rickroll')

Contributing

The library is intended to keep features within the same scope of the original Python 3 library. This may/may not change at my discretion.

Pull requests are welcome, esp. with regards to resolving any API differences that occured through mistakes or otherwise. However, note that I would like to remain with similar API to the original library, so it is unlikely new API features will be approved (unless strictly relevant to the JS/TS version).

The source code is structured almost identically to the Python 3 Library. I've also mocked some other dependencies, this is to maintain readability and ease of changes between the two APIs.
