Spotify Playlist To JSON

Quickly and easily get any Spotify playlist metadata in JSON returned via HTTP API . No Spotify API key required.

How Does It Work?

This app will load a full Chrome browser with no GUI (headless) into memory and load the playlist web page into it. The app will scroll to the very bottom allowing all the lazily loaded AJAX items to be downloaded. At this point go through all the HTML and pull out the necessary metadata. Open all song requests to get album/song cover arts. Returns a friendly JSON response for you or your app to consume.

Getting Started

Prerequisites

Make sure you have these installed:

• Docker
• Docker-Compose

Download and run web service

git clone git@github.com:dantheman213/spotify-playlist-to-json.git
cd spotify-playlist-to-json/
docker-compose up --build -d

Find Spotify Playlists you want to ingest

Look for Spotify playlists that you are interested in and get the Spotify Playlist ID. This can be done in many ways. You can get an ID by right clicking a playlist in Spotify, select the "share via URL menu" option, paste the URL into a text editor, and then extract the ID from the URL to give to the application. This can also be automated programmatically.

Here is an example:

https://open.spotify.com/playlist/3NcxM1LJJdua8AcRxtijNY

Send queries to web service via HTTP API

Here is an example:

http://localhost:3000/playlist/query/3NcxM1LJJdua8AcRxtijNY

Get status and results

Here is an example:

http://localhost:3000/playlist/result/3NcxM1LJJdua8AcRxtijNY
