How to import Nightmarejs into angular-cli component

I'm going to make GUI scrapper with Electron & Nightmare. However when I use just plain html/js as described in Electron quickstart, all works well. But I'd like to make Electron app nicely by using Anugular2(angular-cli webpack). I created project ng new Scrapper then made some routes for components e.g. HomeComponent, SettingsComponent. I installed nightmare in angular project folder by npm install --save nightmare and I would like import it in SettingsComponent like:

import {Nightmare} from 'nightmare'; 

and use it like:

ngOnInit{
  this.nightmare = new Nightmare({
    show: true,
    electronPath: require('node_modules/electron')
  })
}

What have I tryied:

1) in index.html including

<script src="node_modules/nightmare/lib/nightmare.js"></script>

2) then in my component

declare var Nightmare: any;

3) ngOnInit(){

this.nightmare = new Nightmare({})

4) Gettings errors about missing other js files inside node_modules/nightmare/lib/*.js

It is possible to interact with Angular2/Nightmare inside Electron App?
