Debug output

In development mode, it is all good, but it does not work in production build.

** Errors in the JavaScript console **
ERROR TypeError: af(...).database is not a function

Expected behavior

See the next line from console.
AngularFireDatabase {scheduler: FirebaseZoneScheduler, database: Database}

Actual behavior

I am having the same issue but with "af(...).auth" error in the console.

@johnrivelt I`ve met this issue also. You have to import AngularFireDatabaseModule to your module

[johnrivelt]

@AnatoliiOmelchenko, where do I need to add AngularFireDatabase to? I already added it as provider.

[atolyio]

@johnrivelt remove provider AngularFireDatabase, and add to imports AngularFireDatabaseModule http://prntscr.com/oq1b0d

[johnrivelt]

Thanks @AnatoliiOmelchenko, it worked.

Naming convention has changed for new angularfire2, see
https://github.com/angular/angularfire2/blob/master/docs/install-and-setup.md.

//app.modules.ts
//...
- import { AngularFireDatabase } from '@angular/fire/database';
+ import { AngularFireDatabaseModule } from '@angular/fire/database';

@NgModule({
  declarations: [
    AppComponent,
    //...
  ],
  imports: [
    //...
    AppRoutingModule,
    AngularFireAuthModule,
+ AngularFireDatabaseModule,  // add in angularfire 5.2.1 
    AngularFireModule.initializeApp(firebaseConfig),
  ],
  providers: [
    //...	
-   //AngularFireDatabase,  // remove in angularfire 5.2.1 
  ],
  bootstrap: [AppComponent]
})

Still don't know why previous setting worked for development,not for production. 🤷‍♀️
