`javascript
/**

* Adjust as necessary for your application needs.
* Taken from: https://github.com/angular/quickstart/blob/master/systemjs.config.js
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles

CookieService class is an injectable service with angular @Injectable() decorator. Therefore, it needs to be registered in the providers array (encouraged way).
Then, it will be available in the constructor of the component class.
`typescript
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { CookieService } from 'angular2-cookie/services/cookies.service';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule ],
declarations: [ AppComponent ],
providers: [ CookieService ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
`
`typescript
import {Component} from 'angular2/core';
import {CookieService} from 'angular2-cookie/core';
@Component({
selector: 'my-very-cool-app',
template: 'My Angular2 App with Cookies
'
})
export class AppComponent {
constructor(private _cookieService:CookieService){}
getCookie(key: string){
return this._cookieService.get(key);
}
}
