Thank you for the feedback!
- You need worker process only to perform background tasks, like sending e-mail asynchronously. I don’t really remember how I learned that, as I am using Heroku for quite a long time
If no such tasks are present, worker process is not needed (you can send e-mail synchronously, however this is not very user-friendly). Btw, Heroku has new pricing plans. https://www.heroku.com/beta-pricing - Yes, I believe that would be enough, however I had not used such setup myself - rather build authentication from scratch and used CanCan.
- Yeah, Sorcery does not really care about authorization mechanism and CanCan does not care about authentication - it only requires current_user to be present.
Thank you again for kind words, I really appreciate that.
