Rxjs

Any modern web application needs, sooner or later, to perform some http requests to retrieve data. Below, I’ll describe some common scenarios and how to perform such requests using RxJS.

In the particular example, I assumed the http service call was inside the service.getItems method, but it could be a fetch or anything else returning an observable.
