Just started working with React and will also be using GSAP (of course). I found this link helpful: https://egghead.io/lessons/react-using-tweenmax-with-react which unfortunately uses the deprecated getDOMNode in its examples. Simply swap out for findDOMNode and start animating. My project is working fine with simpler sequential animations so far, but simultaneous transformations on a single element may be trickier. I haven't tried the plugin, I'm just loading TweenMax straight, though I may change things up if I run into trouble. So far, so good, though.
