Ionic PRO : deploy build

git push ionic master

Am I correct, at deployment, to device moves just js/css/html scripts, so noneed to prepare package builds?

If yes, how to be if plugins list changed?

Ionic Pro is a hosted and closed source service, so there is not much we, the community, can help you with. You can - and should - contact support at http://ionicframework.com/support#support

What exactly do you mean by “deploy build”?

This is all written not very clear.Can you reword?

as per this video

https://ionic.zendesk.com/hc/en-us/articles/115012004848-Live-Deploy-Setup

git push ionic master
prepare just compilation of javascript/html/css/res sources to prepare to send to device.

In case if cordova plugins list changed, how to manage this case?

And in video, app compils in Xcode, not by :ionic cordova build ios --prod
does it makes sence?
