Интеграция bpmn-js для моделирования компонента реакции

Я создал небольшой компонент, который загружает библиотеку, кажется, работает нормально, возможно, вы пытались реализовать его, не используя жизненный цикл React, очень важно знать, как эта работа для достижения результатов. Большинство библиотек используют dom element, и этот элемент доступен только после рендеринга, поэтому я использовал componentDidMount, чтобы гарантировать это.

Вот основная демонстрация: https://www.webpackbin.com/bins/-KnHgXtsXlkcJJo735S4

Пример компонента:

import React from 'react'
import BpmnViewer from 'bpmn-js'

class bpmnView extends React.Component{
  constructor(){
  super();
    this.viewer = new BpmnViewer();
    this.generateId = 'bpmnContainer'+ Date.now();
  }
  render(){
    return <div id={this.generateId}></div>;
  }
  componentDidMount (){
    this.viewer.attachTo('#'+ this.generateId);

      // import function
  function importXML(xml,Viewer) {

    // import diagram
    Viewer.importXML(xml, function(err) {

      if (err) {
        return console.error('could not import BPMN 2.0 diagram', err);
      }

      var canvas = Viewer.get('canvas'),
          overlays = Viewer.get('overlays');


      // zoom to fit full viewport
      canvas.zoom('fit-viewport');

      // attach an overlay to a node
      overlays.add('SCAN_OK', 'note', {
        position: {
          bottom: 0,
          right: 0
        },
        html: '<div class="diagram-note">Mixed up the labels?</div>'
      });

      // add marker
      canvas.addMarker('SCAN_OK', 'needs-discussion');
    });
  }


  // a diagram to display
  //
  // see index-async.js on how to load the diagram asynchronously from a url.
  // (requires a running webserver)
  var diagramXML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<definitions xmlns=\"http://www.omg.org/spec/BPMN/20100524/MODEL\"\r\n
