Manage tui-loader with interceptor

[luca-sacco]

Hi everyone,
I wanted to centralize the hide and show logic of the tui-loader going to intercept (via interceptor) all the http requests, this to avoid managing the loading at each http request, on all the different parts / components. What do you think about it? The problem I have is in the case of multiple http requests where the concurrency should be handled (the loading appears and disappears continuously for each http request).
Any suggestions?

You can probably create a global singleton service that takes care of it.

So you suggest that the interceptor calls some methods, for example, show() hide(), of a global sigleton where a queue of http requests is managed inside this singleton?

You can make a service with loading$: Observable<boolean> that would count the number of ongoing requests and when this number is 0 emit false, otherwise emit true.
