Reducer on global state

[thaiat]

Hi,

I understand that provideStore will map each reducer name to form the global state.
But how would you add a reducer that acts on the global state ?

[robwormald]

typically, you wouldn't. all state is pretty much "global" (or alternately, "no state is global") - maybe i'm misunderstanding your question?

[robwormald]

this is possible with the new middleware implementation, though that would typically be more for tooling use cases.

I may be wrong, but I think what @thaiat is alluding to is something like this: reduxjs/redux#749. Seems like a valid use-case.

... and see this highly voted answer:
reduxjs/redux#749 (comment)

@robwormald do you know if this is somehow possible with ngrx/store?
