javascript - Will invoking angular.bootstrap on "n" multiple DOM nodes, instantiate "n "AngularJS applications?

Question

Is it correct to say that invoking angular.bootstrap will create a new instance of AngularJS, together with a separate digest cycle, root scope, injector and so on?

If so, is it possible to nest such applications (i.e. invoke bootstrap on DOM nodes inside the DOM managed by another AngularJS app)? (I presume no!)

Answer 1

There's only one instance of Angular. Each app has its own injector though. And since $rootScope is a service this means that every app gets its own instance and in turn its own digest cycle.

Bootstrapping involves compiling the DOM, which means nested Nodes would already be compiled when you try to bootstrap them.
