How to subscribe to all observables in Angular?

Question

Angular

I have a set of services which I do request on the server. Services are scattered across components.

I need to subscribe to all observables and wait for them to complete.

I know to use the forkJoin operator.

The question is more about architecture - namely, what to do with services - that are already written. How to put together all observables in one place and wait for them to be completed?

Answer 1

You need to subscribe to the isStableobservable located at the applicationRef object
