Hello, I have an issue involving SystemJS/CommonJS interop and definition files. I can't find any acceptable solution for now.
My app consists of

• a server part that compiles to CommonJS
• a client part that compiles to SystemJS (flag allowSyntheticDefaultImports on)
• a shared part that is imported (copied) into both client and server parts.
  I cannot figure out how to import some libs like bluebird or lodash without having either the compiler complaining about something or an exception at execution level. I used definitions files provided by DefinitivelyTyped for bluebird/lodash.

I tried all import syntaxes I could find, but without success

import Promise from 'bluebird'; do not compile on CommonJS,

Module '"bluebird"' has no exported member '_'.

import {Promise} from 'bluebird'; still do not compile on CommonJS,

Module '"bluebird"' has no exported member '_'.

import * as Promise from 'bluebird'; compile on both CommonJS and SystemJS, but crashes during execution, on some functions that directly use Promise as constructor

import Promise = require ('bluebird') old syntax compiles on both CommonJS and SystemJS. But crashes at execution on SystemJS, because Promise cannot be used directly as constructor/function.

Error: TypeError: Promise is not a constructor(…)

Do you have any solutions for this problem ? What is the right way to do in this case ?
