I tried out Opa a couple of years ago. At that time you could compile an Opa program down to a single executable that contained the server and database. Coming from a desktop application programming background, I really found this single executable very appealing.
Fast-forward to present. I started looking at Opa again and now I see that it requires node.js and mongoDB on the server side. Is it still possible to create a "classic" Opa application which is just one executable containing the server and database as it was a couple of years ago as an option or has that been completely deprecated? (and if that possibility has been completely eliminated could it be brought back as an option?)
