Description

First of all, thanks for providing such a good content for us all. Second, I have been struggling to setup a good backend API, as you know, many moving parts and workflows to test. While trying to do so, I stumbled on patterns Repository and Service, which are good practices described, among others, on [1]. IT would be very helpful to have such, and extend the current backend counterpart.
