Asynchronous requests and UI responsiveness

a rather naive question here:

I have a service which data was hardcoded for prototyping. Now I would like to link it to server data and am not sure how to synchronize requests and the views currently displayed. Is there an abstract design-pattern for UI and asynchronous requests in general / or more specifically for Angular.js ? I already read about the $q package and deliverables, but how would I synchronize that with the views and stop other background processes?

Thanks, El
