How to add jsoneditor to Stenciljs / Ionic app

I have a Stenciljs app with Ionic components. Whenever I try to import / use JSONEditor, it says:

```
import * as JSONEditor from 'jsoneditor';

var container = document.getElementById("jsoneditor");
var options = {
mode: 'tree'
};
console.log(JSONEditor)
var editor = new JSONEditor(container, options);
```

**_TypeError: JSONEditor is not a constructor_**

How JSON Editor shall be used in my app?
