Firebase APIs outside of an Injection context

Appconfig.ts の Firebase プロバイダーから始め、次に Service の Auth サブスクリプションと Firebase 呼び出し、および Component の signup フローを調べます。injection context の警告がいつ表示されるかを確認しながら、reload と signup の動作を再現します。警告と認証の遅延が解消され、signup や Firestore への書き込みを壊していなければ完了です。

I keep getting error about,

Calling Firebase APIs outside of an Injection context may destabilize your application leading to subtle change-detection and hydration bugs.

I did properly set up the angular firebase integration although signIn, logIn working properly, but this error won't resolve and it makes the authentication delay at each reload.

Appconfig.ts -

const firebaseConfig = {
apiKey: "",
authDomain: "",
projectId: "",
storageBucket: "",
messagingSenderId: "",
appId: ""
}

export const appConfig: ApplicationConfig = {
providers:
[
provideZoneChangeDetection({ eventCoalescing: true }),
provideRouter(routes),
provideHttpClient(),
provideFirebaseApp(() => initializeApp(firebaseConfig)),
provideAuth(() => getAuth()),
provideFirestore(() => getFirestore())
]
};

Service:

auth: Auth = inject(Auth)
fireStore: Firestore = inject(Firestore)
ngZone = inject(NgZone)

userSubject: BehaviorSubject = new BehaviorSubject(null)

private authSubscription;

constructor() {
this.authSubscription = this.auth.onAuthStateChanged(user => {
this.userSubject.next(user)
})
}

signUp(fullName: string, email: string, password: string, username: string, phone: string = '', address: string = '', pincode: string): Observable {
return this.ngZone.run(() => {

  const promise = createUserWithEmailAndPassword(this.auth, email, password)
    .then(response => {
      const userCredentials = response.user;
      if (userCredentials) {
        return sendEmailVerification(userCredentials)
          .then(() => {
            // Update profile with username
            return updateProfile(userCredentials, { displayName: username })
              .then(() => {
                // Save user details in Firestore
                return this.saveUserDetails(response.user.uid, fullName, address, phone, pincode);
              })
              .catch(error => {
                console.error("Error updating profile:", error);
                throw new Error('Profile update failed');
              });
          })
          .catch(error => {
            console.error("Error sending email verification:", error);
            throw new Error('Email verification failed');
          });
      } else {
        throw new Error('User credentials not found');
      }
    })
    .catch(error => {
      console.error("Error during signup:", error);
      throw error; // Propagate the error
    });

  return from(promise).pipe(
    map(() => { }),
    catchError(error => {
      console.error("Error in signup:", error);
      return throwError(() => new Error(error.message)); // Return an error observable
    })
  );
})

}

saveUserDetails(uid: string, fullName: string, address: string, phone: string, pincode: string): Promise {
const userRef = doc(this.fireStore, 'users', uid)

return setDoc(userRef, {
  fullName: fullName,
  address: address,
  phone: phone,
  pincode: pincode
}).then(() => {
  console.log("User details saved in Firestore.");
}).catch((error) => {
  console.error("Error saving user details in Firestore:", error);
  throw error;  // rethrow to propagate error in the stream
});

}

Component:

onSubmit() {
const rawForm = this.signUpForm.getRawValue();

this.loader.showLoader()
this.authService.signUp(rawForm.name,rawForm.email, rawForm.password, rawForm.username, rawForm.phone, rawForm.address, rawForm.pincode).subscribe((next) => {
  this.router.navigateByUrl('/email-ver')
  this.loader.hideLoader()
}, err => {
  console.log('Some error occurred during signup', err);
  this.loader.hideLoader()
})

}
