Support for ES6 modules syntax on IBM bluemix

0 votes

I'm trying to deploy an app that uses ES6 statements on ibm cloudfoundary. the logs are showing that it starts with node 6.8.0, this is the prompt that comes up:

 Unexpected token import

I tried running it on my windows 10 desktop it runs without any hitch:


This is the output:

{ http_parser: '2.7.0',
  node: '6.8.0',
  v8: '',
  uv: '1.9.1',
  zlib: '1.2.8',
  ares: '1.10.1-DEV',
  icu: '57.1',
  modules: '48',
  openssl: '1.0.2j' }

The output is same on my system and bluemix server. but it is not working on bluemix. Here's the package.json:

  "name": "bluemixtest",
  "version": "0.0.0",
  "main": "server/app.js",
  "dependencies": {
  "devDependencies": {
  "engines": {
    "node": "6.8.0"
  "scripts": {
    "start": "node --harmony_modules server/app.js"
  "private": true


'use strict';
import express from 'express';
import mongoose from 'mongoose';

Startup error in logs :

import express from 'express';
