I've upgraded to the latest version of @angular/fire recently, and everything worked fine, but now I've migrated away from the pat libraries, and now I'm stuck with this issue. I get this error on the following code: Firebase: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp().

// ...
import {getAuth, provideAuth} from '@angular/fire/auth';
import {getFirestore, provideFirestore} from '@angular/fire/firestore';
import {initializeApp, provideFirebaseApp} from '@angular/fire/app';
// ...

@NgModule({
  // ...
  providers: [
    // ...
    provideFirebaseApp(() => initializeApp(window['firebase_config'])),
    provideFirestore(() => getFirestore()),
    provideAuth(() => getAuth()),
    // ...
  ],
  // ...
})
export class ApModule {
  // ...
}

Here is the stack trace:

I'm totally confused on why I'm getting this error. Any help is much appreciated!

Apparently the issue was a mismatch in versions between firebase and @firebase/app. Because of this mismatch, firebase was actually loaded into memory twice, but only instantiated once.

The docs suggest that the code you put in the providers should the in the imports.

import { provideFirebaseApp, getApp, initializeApp } from '@angular/fire/app';
import { getFirestore, provideFirestore } from '@angular/fire/firestore';

@NgModule({
  imports: [
    provideFirebaseApp(() => initializeApp({ ... })),
    provideFirestore(() => getFirestore()),
  ],
  ...
})
export class AppModule { }

Yes, do an ng-update - update all pkgs listed

Humm.. ok, I am using version 9 upgraded from 8 in my project, and either you mented out some things or you indeed are missing some stuff. Let me share my module:

const providers = [
 // ...
  AngularFireModule,
  AngularFireAnalyticsModule,
  AngularFireAuthGuard,
  ScreenTrackingService,
  UserTrackingService,
  AngularFireAnalytics,
  {
    provide: ANALYTICS_CONFIG,
    useValue: {
      APP_NAME: appConfig.appName,
      APP_VERSION: appConfig.appVersion
    }
  }
];



@NgModule({
  imports: [
    // ...

    /** Firebase Modules */
    AngularFireModule.initializeApp(firebaseConfig),
    AngularFireAnalyticsModule,
    AngularFireAuthGuardModule,
    AngularFireDatabaseModule,
    AngularFireFunctionsModule,

    // ...
  ],
  providers,
  bootstrap: [RootComponent]
})

So my initialize app is at my imports and not on my providers, I remember I had some issues back then and after some digging and changing I came up with the above and it worked for me. As you can see I use quite a few of their services.

From the error you posted, I would guess the problem is your initializeApp not doing the initialization, so make try to move it to imports and make sure the config file has all the required properties.

==UPDATE==

Please note that I pasted my project imports, you may ignore everything else other than the AngularFireModule import and providers, since you may not use the others, I just added them for reference as they could be useful to other people.
