I'm still working with your great repo and app. May I ask if you can give me hint how I can deploy your app, e.g. to Heroku? I'm struggling with packaging as well as starting. I tried to build a big-fat JAR, but then I haven't a clue how to start the Boot process (like from the console) to verify that my JAR was built correctly. Maybe you have a spontaneous idea how to do it? Thank you!
