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,

Answer 1

Make sure FireBaseDatabaseModule is imported from angularfire2/database-deprecated if youre using FireBaseDatabase from angularfire2/database-deprecated

and vice-versa. The only problem is the mismatch of import statements because they need to belong to the same package either

angularfire2/database or angularfire2/database-deprecated

if you would try to import the database from the first and the module from the second package or vice-versa. It wont recognize it as a DatabaseModule or Database.

------------ ROOT MODULE -------------

    import { AngularFireDatabaseModule } from "angularfire2/database-deprecated"
    imports: [
        BrowserModule,
        RouterModule.forRoot(appRoutes),
        FormsModule,
        AngularFireModule,
        AngularFireDatabaseModule,
        AngularFireAuthModule,
        AngularFireModule.initializeApp(environment.firebase)    
]

------- SERVICE CLASS ------------

import { AngularFireDatabase, FirebaseListObservable } from "angularfire2/database-deprecated";
