Spotify playlist collaboration through Slack. Based on SlackBox.

Simply create a Slash Command, such as /jukebox, which accepts a track name (also the artist too for a less fuzzy search) to add to a pre-defined Spotify playlist:

/jukebox Bell Biv DeVoe – Poison

And/Or add it as a listener on your slack channel; paste YouTube/Spotify links to get your song added to the shared playlist!

First you'll want to create your Slack Slash Command, which you can do by going to your Slash Commands page.

During setup, have your slash command submit a POST to your app's /store endpoint, e.g. https://app-name.herokuapp.com/store.

Make a note of the Token, as you'll need it later to help guard against cross-site request forgery.

1. Head to Slack > CustomIntegrations > Outgoing Webhooks and add a new configuration. Set the Channel to listen to, and add your app's /parse endpoint (e.g. https://app-name.herokuapp.com/parse) to URL(s). Make a note of the Token, as you'll need it later to help guard against cross-site request forgery.
2. Head to Slack > CustomIntegrations > Incoming Webhooks and add a new configuration. Note the Webhook URL for the settings and customize the look of the incoming message bot to your preference.

Head over to Spotify's Developer Site and create a new Application. Make sure you add whatever slackbox's callback URI as a valid callback URI. If you're running locally, this will be /callback endpoint (e.g. on Heroku https://app-name.herokuapp.com/callback).

Make a note of the key, secret and callback URI too, as you'll need these later as well.

Also, don't forget to make a playlist. If you do this through Spotify's web interface then the playlist identifier will be the last segment of the URI - make a note of this too! If there's a better way of finding this out, we're all ears. If you do this through the app, right-click the playlist to get it's web URL and again, you need the last segment of the URI.

Once you've cloned OneJukeBox or hit the "Deploy with Heroku" button you'll need to setup the following environment variables. These can either be stored in a .env file or set up as config variables in Heroku.

• SLACK_TOKEN - The token from Slack's Slash Command.
• SLACK_TOKEN2 - The token from Slack's Outgoing Webhook.
• SLACK_INCOMING_HOOK_URL - The WebhookURL from Slack's Incoming Webhooks.
• SPOTIFY_KEY - Your Spotify application key (a.k.a Client ID).
• SPOTIFY_SECRET - Your Spotify application secret (a.k.a Client Secret).
• SPOTIFY_USERNAME - Your Spotify username.
• SPOTIFY_PLAYLIST_ID - Your playlist identifier.
• SPOTIFY_REDIRECT_URI - URI to redirect to once your user has allowed the application's permissions.

Visit your OneJukeBox's /authorise end to authenticate yourself with Spotify and you should be all set!
