Load Stage with JSON String

To deserialize a JSON string with Konva, we can use the Konva.Node.create()
method which creates a node from a JSON string. If we want to deserialize
a stage node, we can also pass in an optional container parameter.

That methods works for very small apps. For more complex cases take a look into Complex Load or even better to Best Practices

// create node using json string
var stage = Konva.Node.create(json, 'container');
