HTML5 Canvas Tweening Tutorial

To tween properties with Konva, we can instantiate a Konva.Tween object
and then start the tween by calling play(). Any numeric property of a Shape,
Group, Layer, or Stage can be transitioned, such as x, y, rotation,
width, height, radius, strokeWidth, opacity, scaleX, offsetX, etc.

For a full list of attributes and methods, check out the Konva.Tween documentation.

// the tween has to be created after the node has been added to the layer
var tween = new Konva.Tween({

// start tween after 2 seconds
setTimeout(function () {;
}, 2000);
