What is the limit (in terms of data size) of $rootscope?

Try populating scope instead of rootscope as rootscope is shared across multiple apps but scope could be private.

 

You are planning to use rootscope to display data in View(html) with the help of angular controller.

 

Just to inform, These are context java script objects in angular. One is scope and other rootscope.   It acts as connector between controller and view. Angular renders view with the help of controller and  view data placeholder {{AAA}}  could be populated with help of scope during that process.  You can have single rootscope and multiple private scope javascript objects which could be used to render data.

 

About size limit. What is the size are you looking for? It should be quite good in handling good anount of data in angular.
