Questions tagged [spotify-app]

The Spotify App API is no longer supported by Spotify. It allowed developers to work with Spotify using modern web technologies. For Spotify API questions that are not about the App API, use the [spotify] tag.

The Spotify platform allowed 3rd party developers to create applications using the Spotify Apps API as web applications integrated into the desktop product using Chrome Embedded Framework. It is no longer accepting new changes - announcement.

What Questions should I ask?

Questions using this tag should be about how to use one of these platforms. You may find that, in some cases, a question that arises while developing for these platforms is not Spotify specific; e.g. a common JavaScript question while creating a Spotify App. In many cases, you should tag your question with the tag instead. However, the Spotify platform does have its own idiosyncrasies, so may be appropriate. It is also advisable to include the tag as well, to ensure wider visibility.

Platforms

Spotify Apps API

The newest addition to the platform is the Spotify Apps API, which allows developers to create applications which are tightly integrated to the Spotify application. Such applications are created using a mix of HTML5, JavaScript and CSS. Because of this, as well as the official documentation's usefulness, developers should also find any documentation on HTML5, JavaScript, and CSS (such as the Mozilla Developer Center) useful.

The JavaScript API accessible within the Spotify App environment gives access to classes representing Albums, Tracks and Artists; amongst others.
