Missing EventEmitter on recent RCs of @angular/cli

[kamilkisiela]

An error:

eventemitter3_1.EventEmitter is not a constructor

It happens inside a project that has been created by @angular/cli@^1.0.0-rc.1.

---

In client.ts, we've got this:

import { EventEmitter } from 'eventemitter3';

In eventemitter3/index.js:

EventEmitter.EventEmitter = EventEmitter;
export default EventEmitter;

Webpack creates a bundle file that contains that:

var _eventemitter3 = require('eventemitter3');

// inside SubscriptionClient of `subscriptions-transport-ws`

this.eventEmitter = new _eventemitter3.EventEmitter();

The thing is, _eventemitter3 has no EventEmitter property assigned. It's missing...

console.log(_eventemitter3); // EventEmitter class
console.log(_eventemitter3.EventEmitter); // undefined

When you look up for the eventemitter3 package inside the bundle file, there's no EventEmitter.EventEmitter but there's another property available that has been assigned the same way (EventEmitter.prefixed). It somehow removes the assignment from the code.

Weird...

Any progress on this?

having the exact same issue

Same issue also here. even with subscriptions-trasport-ws@0.5.5. I also tried to upgrade the eventemitter3 dependency with no luck.
this issue is preventing to setup a ws communication with opengraph servers. Is there any workaround at least?
And I'm using angular cli 1.0.0 stable, not RC

check: npm ls eventemiter3
packages are using the eventemiter3 e.g karma uses 1.x
solution: npm i eventemitter3@2.0.3 --save
