I am facing a situation in my AngularJS project where I have two controllers - controller 1 is constantly present in the view, while controller 2's visibility can change based on the view. In order to ensure that controller 1 has access to certain scope variables, I am considering passing the entire scope of controller 2 to controller 1 during loading. However, I am concerned about potential performance implications on the page. Is this approach risky in terms of performance?
Sharing data between controllers can be achieved through inheritance, but it is not possible to directly transfer a scope from one controller to another and completely replace it.
One approach could be to broadcast events with data between controllers or store the data in AngularJS services such as a factory. These services act as singletons, ensuring that the data remains consistent unless the application is restarted.
Additionally, for better performance, using a service to store data is recommended. This allows the data to serve as a simple Data Transfer Object (DTO), eliminating the need for unnecessary double-binding and potentially improving the speed of the $digest cycle.
Best regards
