Help with Ruby on Rails w/ Webpacker+ReactRails integration

I am really excited to tinker with this library, but I am totally lost trying to get it to render properly. Can someone help me figure out why I'm seeing this error?

I'm assuming this is why? Uncaught ReferenceError: exports is not defined

Am I missing a dependency? I installed all of the dependencies listed in the help guide.

Here's my package.json file.

  "private": true,
  "dependencies": {

  }
}

Workflow Demo component:

import React from "react"
import PropTypes from "prop-types"

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

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

class WorkflowDemo extends React.Component {

  render () {

    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 (
      <React.Fragment>
        <CanvasWidget engine={engine} />
      </React.Fragment>
    );
  }
}

export default WorkflowDemo

Thanks in advance and sorry if this is a total n00b question.
