Apologies as I can\'t think of a better way of including all the information... When I run this, I get an error saying the following. I\'ve followed the Ionic Docs to the T,
Inside app.module.ts add below:
import { AngularFireModule } from 'angularfire2';
import { AngularFireDatabaseModule } from 'angularfire2/database';
Then import as below:
@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    AngularFireModule.initializeApp(firebaseConfig),
    AngularFireDatabaseModule
  ],
Inside home.ts use as below:
import { AngularFireDatabase, FirebaseListObservable } from 'angularfire2/database';
items: FirebaseListObservable;
  constructor(public navCtrl: NavController, db: AngularFireDatabase) {
        this.items = db.list('/items');
  }

Ionic Framework: 3.1.1
