Java/Spring Boot and AngularJS web application to generate a "latest additions" playlist of the most recently added tracks from a user-selected set of Spotify playlists. Built with spotify-web-api-java library.

Links:

• Heroku web app (note that application is running on free dynos, so it may take up to 30 seconds for first load of application)
• Swagger UI
• Travis CI

Tools:

• Java/Spring Boot
• AngularJS
• Material AngularJS
• Spotify Java API
• MongoDB
• Heroku

If not already authorized, click "Authorize" button to connect your Spotify account to the application.

The left panel is where the specifications for the playlist to be created belong, such as the name and description for the playlist. If you have previously created a playlist with the app, you can instead check the "Overwrite existing playlist" option to select a previously created playlist to overwrite.

In the right panel, all of your playlists (including those that you follow) are displayed; from there you can select the playlists to generate the "latest additions" playlist from. The radio buttons and filter allow you to limit and sort your playlists according to the specified query. The "information" icon beside each playlist can be clicked to open a dialog containing more information about the given playlist.

Other todos:

• load selected feeder playlists for existing playlist
• cache loaded playlists instead of making API call on every refresh
• set minimum amount for skip track calls
• inform users if any local tracks are skipped?
• include playlist title in mongodb document

Main application view:

Upon clicking the info button next to each playlist name, a popup dialog opens containing more details about the playlist including its title, owner, description, and number of tracks.

Upon successful playlist creation after submitting the form, a popup dialog opens showing the first 10 tracks of the playlist, and linking to the playlist on Spotify.
