es6 node not properly importing - node.js

Question

I have the following export statement in app.js:
export default class App {
...
}
Now I have the followinng import statement in main.js:
import App from '../../src/app.js'
This should work, I have done it always like this without problems, but somehow App is undefined.
Now when I do the following:
const App = require('../../src/app');
App is an object that contains the property 'default' which holds the 'App' class. Can someone please explain what I am missing here?

It's kind of annoying but I'm pretty sure Node doesn't support ES6 import OR export syntax.
Here's a stackoverflow post that addresses this in greater detail.
How can I use an es6 import in node?
