title: Node.js & amcharts4 - Import error 'Unexpected token export' using TypeSript or ES6
body: <p>I just downloaded your amCharts4 version into my node.js app via npm to test it. Wenn installed I find the files chore.js and charts.js in MyNodejsApp/node_modules/@amcharts/amcharts4 :</p>
  
  <pre><code>MyNodejsApp

  </code></pre>
  
  <p>In my routes/index.js I'm integrate the necessary files:</p>
  
  <pre><code>const { am4core } = require("@amcharts/amcharts4/core");
  const { am4charts } = require("@amcharts/amcharts4/charts");
  
  /home/MyNodejsApp/node_modules/@amcharts/amcharts4/core.js:8
  export { System, system } from "./.internal/core/System";
  ^^^^^^

  <p>Edit: Import gives me also an error</p>
  
  <pre><code>import * as am4core from "@amcharts/amcharts4/core";
  import * as am4charts from "@amcharts/amcharts4/charts";
  
  /home/MyNodejsApp/routes/index.js:12
  import * as am4core from "@amcharts/amcharts4/core";
  ^^^^^^
  
  SyntaxError: Unexpected token import
