This is helpful, thank you. One note: > Selectors: the summary is a denormalized view of the normalized state. Many would argue it is not a business logic but a display logic. Same for the sorting. Yes, I read about that before. Don't put in the store what can be computed. But in my case, this isn't used in a view, but in a separate "object" that can be shared with others without sharing the underlying data. So, while the report attributes are all computed, they must be stored somewhere for later individual retrieval. Anyways, could you please clarify this: > So yes you have 4 functions for your todo business logic Where do I bundle these 4 functions so that they're called always in the same order? > It takes a bit of practice to figure out what is the right cut-off point. Yes, that's my struggle right now ;)
