// load minimal version of 'react-konva`
import { Stage, Layer, Rect } from "react-konva/lib/ReactKonvaCore";

// minimal version has to support for core shapes and filters
// if you want import a shape into Konva namespace you can just do this:
import "konva/lib/shapes/Rect";

import Konva from 'konva/src/Core';
// now you have Konva object with Stage, Layer, FastLayer, Group, Shape and some additional utils function
// so there are no shapes (rect, circle, etc), no filters, no d&d support.


// but you can simply add anything you need:
import 'konva/src/shapes/rect';
//now Konva.Rect is available to use
