The new angular component router is changing quickly.
The current docs on angular which can be found here seems to be outdated
https://docs.angularjs.org/guide/component-router
The documentation ask for the following
npm install @angular/router –save
As of April 2016, the way to install the new angular component router using NPM is
npm install @angular/router@0.2.0 --save
Once installed, include it in your script
<script src="/node_modules/@angular/router/angular1/angular_1_router.js">
