react-router and different transitions

Hey guys... first, thank you for this component and your work.

I'm struggling on trying to reproduce this behavior: http://ionicframework.com/docs/api/directive/ionNavView/ (the transition animation)

If go to another page, slideIn, but if back, slideOut...

I'm using react-router v4 and trying to work on top of the example on router site: https://react-router.now.sh/animated-transitions

But, I'm not going on the right way I think... can you give me any idea of how to do this??

Start with the react-router v4 animated-transitions example linked in the issue and compare it with the requested Ionic-style forward and backward transitions. No repository file, test, or concrete change is identified; the work would first require defining the expected transition behavior and a verifiable completion condition.
