Keep data in service, or in Pages?

So that means Observable kills Promises - in a way that i can always use Observable in place of Promise?

Observables are more complicated, especially when it comes to error trapping. So you have more control, but you need to learn more sophisticated concepts.

ok i get it. Can u just pls post full example with observable? page and service code? :slight_smile: So i can get complete picture. Thx for your time…

When I was first learning Ionic, I bought Josh Morony’s book on Ionic, and the Fullstack.io book on Angular. Both excellent purchases, I recommend them.

ok one more question. That async pipe works only with observables or also with promises? And can i use async pipe some how, when i use variable with observable/promise in NgIf? For example if i want to display something depending on settings object - to be more precise

ngIf=settings.user

in which settings is Observable/Promise for example?
