Angular Frondend app with multiple 'decoupled' modules

[Megabyzus]

Hi Megabyzus,
1. I can confirm that the combination of getSubscriptions and then getItems, as per your pseudocode of NOTE 1, is a good solution since there is no direct method that returns the set of active subscriptions for a given list of Items.

Thanks. To be clear, since there is no 1 - 1 correspondence between items and subscriptions (i.e. we can have multiple subscription references to the same items and vice versa) then my pseudocode needs to be modified to return an array of subscriptions for identical items. Then those array elements need to be individually unsubscribed. In other words, questions 1 & 2 in my mentioned post were related.

Thanks!
