Continuous Integration in an Ionic App?

I have a question regarding continuous integration service such as travis CI or other to use with Ionic application when in development mode. Is anyone using it (especially for production level apps)? Or are there other ways to do a similar process?

May be it is not valid at all for Ionic applications, I am open to hear your views…

There are several providers that offer specific support for Ionic products. Googling should bring you quite far.
