Intellij NodeJs 6.4.0 unexpected token export - node.js

Question

I'm using Intellij Idea to create a NodeJs application in ES6.
My node.exe version is version 6.4.0
I created a simple class :
//wNodeClasses.js
'use strict';
export class wsUrl
{
constructor()
{}
}
I import the module in another file :
require('../../../Root/Libs/Waldata/wsNodeClasses');
When I start the application I always get the error :
d:\Dev\webDev\Root\Libs\Waldata\wsNodeClasses.js:11
export class wsUrl
^^^^^^
SyntaxError: Unexpected token export
at Object.exports.runInThisContext (vm.js:76:16)
I don't use any transpiler , I want to write "pure ES6 code" (I don't want to use Babel or any equivalent)
I understand that NodeJs 6.4.0 can interpret directly ES6 code
Here is my Node.Exe command line :
-max-old-space-size=8192 --expose_debug_as=v8debug
I am a newbie, I suppose I'm missing something obvious, I googled around and I didn't found an answer

Answer 1

I finally found the issue.
NodeJs 6.4.0 with chrome V8 doesn't support Es6 "export" keyword or syntax.
I found a work around using
//Module file
module.exports=
class wsUrl
{
}
and in the consumer :
var wsUrl = require('../../../Root/Libs/Waldata/wsNodeClasses');
...
var MyVar = wsUrl new("test");
I'm still searching to have multiple classes in a same Js file (module) and export them

Answer 2

Thanks for your answer.
I used a different technic (I assume it's just a matter of personal preference) :
//In the module module.exports.myClass1=class myClass1{}
module.exports.myClass2=class myClass2{}
//In the main file (consumer)
var myModule = require('../../../Root/Libs/Waldata/wsNodeClasses');
...
var test=new myModule .wsUrl("param");
This works for me with NodeJs 6.4.0 and intellij (or webstorm)
