error when importing modules with es2015 syntax and babel transpilation to es5

Question

I got problems with transpiling es2015 code to to ES5. Problem happens with module imports:

import * as express from "express"

is transpiled to:

var _express = require("express");
var express = _interopRequireWildcard(_express);

Which cause the error:

var app = express();
          ^
TypeError: express is not a function

But if I import with

var express = require('express');

all works fine.

I still want to use es2015 syntax, is there a setting or plugin I should Install in bable to have it work properly ?

Looks like you should be doing `import express from "express";` when express doesn't support ES6 modules yet — Bergi, Jul 05 '16 at 11:06
it's not related to express specifically, it's general issue with modul import. Your solution works, altough it says express doesn't have a default export. — Robert Brax, Jul 05 '16 at 11:08

I upgraded to node js 6 which supposedly support all es6 features, and even my own files report 'unexpected' tokens.... why is that ? – Robert Brax Jul 05 '16 at 14:19
Node 6 does not support all ES6 features, it does support the vast majority of them though. – loganfsmyth Jul 05 '16 at 15:16
