How to serialize and deserialize Konva stage with Vue?

Pure Konva has special mechanizm to save/load full canvas stage with node.toJSON() and Node.create(json) functions.
See demo.

But we don’t recommend to use these methods if you are using vue-konva. In vue-konva you should have a state of the app defined in your vue components. That state maps into nodes with templates. To save/load full stage you just need to save/load state of the app and you don’t need to save Konva internals and nodes.
