Can we use angularjs in phonegap app?

[Rgb Aston]

Can we just copy angular.js file in the folder and use it in index.html. Does it have any side effect?

[mharr]

Yes, you can.  For example, the Ionic framework for creating mobile (PhoneGap) apps depends on using angular.js.

One of the great characteristics of AngularJS is that it's NOT an all-or-nothing framework. You can use it in a small section of a page, the entire page or not on a given page at all. And as mharr stated, you can build an entire application with AngularJS - as with Ionic. 

You can also look at Angular Material as another library that leverages AngularJS to build mobile apps.
