IMHO NgRx would really benefit from a Akita-like solution that transforms a service into methods in actions+reducers. For a larger project, actions+reducers start multiplying like there's no tomorrow.
There are pet peeves of mine I didn't mention, like the need to declare the reducers in StoreModule (when Angular has builtin Dependency Injection), weird AOT issues when dealing with different libraries, such as ngrx-forms + ngrx-actions.
I would still recommend NgRx to a team that's familiar with React, though.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
