Epic Collection helps you reclaim space in your Spotify library when you have reached the limit of 10000 tracks. It interactively moves albums to playlists, keeping all your music around.

I made this app to work around Spotify's library limit, and as an example React application with a traditional layered architecture, removing the complexity that state-management libraries bring.

You'll find the frontend application itself in the frontend directory. At the top level, there is a Gradle project used for browser-based acceptance tests.

All tests can be run with:

CI=1 MOZ_HEADLESS=1 ./gradlew clean npm_install npm_test test

The acceptance tests expect a current version of Firefox to be installed.

Most tests are in frontend where they can be run with CI=1 npm test.

The app can be deployed to CloudFoundry (Staticfile buildpack) by manually running deploy.sh. The script expects cf-cli to be present, logged in and targeting the right space.

Deploying anywhere else should be pretty straight-forward:

• npm run build
• index.html should be served as a fallback for all paths
• service-worker.js should never be cached
