Spotify PromoCards API
An unofficial generator for Spotify style shareable song cards.
What it is
Spotify makes those shareable song cards inside its own app. This API makes one for any track, album or artist from a URL, so you can embed it anywhere.
How it works
Express fetches metadata and artwork from the Spotify Web API, samples a background colour from the cover, and draws the card with node-canvas. Packaged in Docker. My first project that other people actually used.
