angular - How to inject FirebaseApp in Angular2 service to use firebase.storage() with AngularFire2 -

i'm using angularfire2 version 2.0.0-beta.6

i wrote database.service angularfire injection (see extract database service code).

it's ok usage.

but i'd integrate usage of firebase storage() api. can't inject firebaseapp in constructor's service use in component :

constructor( @inject(firebaseapp) private firebaseapp: any) {} 

extract of database service :

import { injectable } '@angular/core'; import { angularfire, firebaseapp, firebaselistobservable } 'angularfire2';  @injectable() export class databaseservice {    constructor(private af: angularfire) {     this.init();   } ... service function  }
