Update your Slack status based on the track currently playing in Spotify.

You can update your status via the /spotify-status command in Slack once you've added the app to your team's Slack.

You will need PostgreSQL, Bundler, RubyGems, and Ruby installed.

Create a Spotify app. Add http://localhost:9292/callback/spotify as a redirect URI.

Create a Heroku app.

bundle install
cp dotenv.sample .env

Create a Slack app. Add http://localhost:9292/callback/slack as a redirect URI. Set up a "Slash Command" on your app with the name /spotify-status and the request URL https://your-heroku-app.herokuapp.com/command/spotify-status. When you add the slash command to your Slack app, a verification token will appear under "Basic Information". Set this token in your .env as SLACK_VERIFICATION_TOKEN.

Edit .env to set your Spotify and Slack client IDs and secrets. Run rake generate:secret and put the output of that as the SESSION_SECRET value in your .env.

createdb spotify_slack_status_dev
rake db:migrate
rackup
open http://localhost:9292/

Set https://your-heroku-app.herokuapp.com/callback/spotify as a redirect URI on your Spotify app. Set https://your-heroku-app.herokuapp.com/callback/slack as a redirect URI on your Slack app. You want the Heroku URL as the first redirect URL.

heroku git:remote -a your-heroku-app
git push heroku master
heroku run rake db:migrate
heroku restart

Set environment variables on your Heroku app via:

heroku config:set SPOTIFY_CLIENT_ID=
heroku config:set SPOTIFY_CLIENT_SECRET=
heroku config:set SLACK_CLIENT_ID=
heroku config:set SLACK_CLIENT_SECRET=
heroku config:set SLACK_VERIFICATION_TOKEN=
heroku config:set SESSION_SECRET=
