import 'gsap';
import TweenMax from 'gsap';
import Draggable from 'gsap/Draggable';
These are the imports, and this is a small portion of the code that uses _gsTransform
Draggable.create("#foo", {
type: "rotation",
bounds:{ minRotation:0, maxRotation:270 },
onDrag: function () {
angle = $("#foo")[0]._gsTransform.rotation;
tell me if you need something more
