I can't see the any nodes.

import React from 'react'; import logo from './logo.svg';

import createEngine, { DefaultLinkModel, DefaultNodeModel, DiagramModel } from '@projectstorm/react-diagrams';

import { CanvasWidget } from '@projectstorm/react-canvas-core'; import './App.css';

const App = () => {

// create an instance of the engine with all the defaults const engine = createEngine(); // node 1 const node1 = new DefaultNodeModel({ name: 'Node 1', color: 'rgb(0,192,255)', }); node1.setPosition(100, 100); let port1 = node1.addOutPort('Out');

// node 2 const node2 = new DefaultNodeModel({ name: 'Node 1', color: 'rgb(0,192,255)', }); node2.setPosition(100, 100); let port2 = node2.addOutPort('Out');

// link them and add a label to the link const link = port1.link<DefaultLinkModel>(port2); // link.addLabel('Hello World!');

const model = new DiagramModel(); model.addAll(node1, node2, link); engine.setModel(model); return (
<CanvasWidget engine={engine} /> ); }

export default App;

This is a package.json.

This is a source code I tried. But nodes are not shown. I can't see anything.

It seems you are importing CanvasWidget, but you are not using it. That is the component that renders out your diagram model.

If you refer to this demo. Take line 40 and try again, you should be able to see it.
