Deleting shapes

There are two very close methods remove() and destroy(). If you need to completely delete a node you should destroy() it. The destroy() method deletes all references to node from the KonvaJS engine. If you are going to reuse a node you should remove() it then later you can add it again to any container.

Tweening

When you are using Konva.Tween instance you have to destroy it after usage.

var tween = new Konva.Tween({
    node : circle,
    x : 0,
    duration : 0.5,
    onFinish : function() {
        // remove all references from Konva
        tween.destroy();
    }
});
tween.play();

Or if you don’t need to reuse the tween you can use the new to() method:

// the tween will be automatically started and destroyed on finish
circle.to({
    x : 0,
    duration : 0.5
});
