YouTube-Playlist-downloader-with-cover-art

Semi-automatic script to download videos from youtube playlist to mp3 files with cover art for offline usage
This is a side project.
It is not production ready code

Why?

I listen to my music offline.
Simply not enough data.
But I like my music to have cover art.
In android, cover art is displayed for each folder if there is any.
So if you have 10 songs, for the correct cover art to be shown, each song needs to reside in its own folder
Also if I have a playlist of 1000+ songs - manually downloading is too much of a waste of time and tedious
It also acronyms the folder into file name so it is easier to find in music player

Step 1

Go a youtube playlist page for example like this one Make sure you scroll all the way to the bottom and all the entire playlist is loaded correctly.
This is very important!
Run this code in Developer Tools

function run(){
    function  extractVideoURLsFromPlaylist()  {
		let  urls  = []
		let  div  =  document.querySelectorAll('#contents > ytd-playlist-video-renderer')
		let  hrefClass  =  '.yt-simple-endpoint.style-scope.ytd-playlist-video-renderer'

		for (let  d  in  div) {
			div[ d ].querySelector  &&  urls.push( div[ d ].querySelector(hrefClass).href )
		}
		return  urls.join('\n')
	}
	return extractVideoURLsFromPlaylist()
}
run()

It should print a URL per line Copy this and paste it in a YOUR_NEW_FILE.txt Make youre YOUR_NEW_FILE.txt is in the Playlists folder and Playlists is located in the same directory as FileNames.json

Step 2

Locate the file FileNames.json and paste the following in your file:

{
	"name":  "YOUR_NEW_FILE Name",
	"done":  false,
	"completed":  0,
	"lastDone":  "",
	"stats":  []
}

Step 3

Create a new folder by name: MEDIA (Can be anything) Open the terminal/bash/cmd in the folder where index.js and FileNames.json resides

run node index.js and follow the on-screen instructions Enjoy!
