Create spotify playlists that contain other spotify playlists, and then easily update the resulting playlists. Supports custom sorting of the resulting playlists and lets you import/export your data.
This is a serverless app (except for Spotify, of course), so it only needs static file hosting. Because there is no backend, all logic is done in the website and so I chose to use Typescript.
Requires having node.js installed on your system. I am using node.js 16. npm version 7+ is required.
Copy src/config.example.ts to src/config.ts and fill in values with your own Spotify developer application settings.
Run npm i to install dependencies.
Run npm start and visit http://localhost:3000.
