Angular 2 : what make a service to be “Outside” angular zone?

Question

After having same issues as many people on StackOverflow i didn\'t manage to understand what is an \"Outside angular zone\" Service ?

I\'ve checks all existing question

Answer 1

As far as I know, it is not possible to check whether something runs "Inside" or "Outside" angular zone. If you use zone.runOutsideAngular it runs outside your zone. Second comes to my mind: Why would you want to know?
