I know this might sound a little crazy but here goes.
We have built an entire application in Ionic + angular. We have a big problem though, the performance of the page transitions and scroll is very poor. Obviously we will be optimizing but some of our transitions I don't think are going to work regardless of the efforts we make.
Last night in an effort to solve this problem I found Famo.us and liked what I saw. The problem is that we are on a tight deadline and we cannot afford to port the whole application to Famo.us and our developers have only just overcome the learning curve of Ionic and angular.
Is it possible to just use some parts of Famo.us but keep our Ionic core app. Essentially I would like to build the layout, left/right horizontal scroll, up/down vertical scroll, menu, popups etc.. with Famo.us and leave the content using the Ionic framework?
Any help would be much appreciate, also if we can be pointed in the right directions a new library which is a marriage of both could be incredible, shallower learning curve and all the benefits of Ionics, build tools and easy use with Famo.us' excellent power and rendering!
Alright so i'm dealing with something similar here (pushing Ionic slidebox to its limits, trying to lazy-load slides into the slidebox to improve performance, etc)
There's a good chance that if you switch to Famo.us for the UI of your app, you can reuse a substantial portion of your services, controllers, etc. So to answer your question, yes, you can keep parts of your ionic app and swap out other portions for Famo.us. Your 'content' wouldn't be 'Ionic' though - it would be Angular.
Make sure to use Famo.us+Angular here: https://github.com/Famous/famous-angular
Another option you can try is to use Famo.us AND Ionic, using this generator to help you scaffold it out. Personally I prefer just using one or the other though.

Good luck!
