问题
I have two top level controllers, and now that Controller is deprecated, I'm wondering how to convert them to whatever it is they need to be.
回答1:
In the answer of a similar question it was already mentioned that even though Controller is already deprecated there is no replacement yet but will be before 1.0.
As far as I read from recent issue updates Template is planned to become the replacement for Controller and Decorator/Directive. I haven't checked but I think it is not yet shipped in 0.11.0.
My understanding is that Template is a combination of Controller and Component without shadowDOM.
