Answer 1

KonvaJs comes with mobile events to provide support for mobile devices. All you need to do is to listen to those events as well. I have changed the events to touchend, touchstart & touchmove. So now it will work on mobile. Here's the plunkr.

stage.on('contentTouchstart.proto', () =>{});
stage.on('contentTouchmove.proto', () =>{});
stage.on('contentTouchend.proto', () =>{});

Note: If you want to provide support for both you need to set listners for both.

Hope it helps.
