YTMusic API

YouTube Music API (Unofficial) is a YouTube Music data scraper. It comes with TypeScript support API for return types. The NPM Package can be found here

Motivation

I used to use youtube-music-api as my youtube music api data scraper. I liked looking into the source code of how it works but it never made sense to me. I also didn't like that there were no TypeScript annotations for the return types of methods. Because of this, I decided to build my own version of a youtube music api with TypeScript annotations, testing and written in a way I can understand.

Features

• TypeScript Support for data return types
  • Data from YouTube can be inconsistent but YTMusic API has been tested and the data matches the TypeScript types 95% of the time
• Scrape information directly from YouTube Music API
  • Search Suggestions
  • Songs
  • Videos
  • Artists
  • Albums
  • Playlists

The function when nothing is passed as the category returns a Promise<SearchResult[]> which are the search results of all categories

ytmusic.search("Lilac").then(results => {
	console.log(results)
})

When you pass in "SONG" as the category,

Credits

A lot of the credit should go to youtube-music-api. I build this package as a refactored and tested version of youtube-music-api with TypeScript annotations

Testing

YTMusic API's data return types are tested with Mocha. To run the tests, run the command

$ npm run test
