After upgrading to Ionic 3 with Angular and AngularFire2, an error occurred indicating a lack of provider for the AngularFireDatabaseModule

Recently, I made some updates to my project where I am utilizing ionic 3, upgrading angular to version 5.0, and also updating angularfire2 to version 5.0. Despite resolving various errors along the way, I have encountered a new issue that has left me confused. The error message reads:

Uncaught (in promise: Error: StaticInjectorError[AngularFireDatabaseModule]: StaticInjectorError[AngularFireDatabaseModule]: NullinjectorError: No provider for AngularFireDatabaseModule!

In my app.module.ts file, I have the following setup:

...

import { AngularFireDatabaseModule } from 'angularfire2/database'

...

imports: [
    BrowserModule,
    BrowserAnimationsModule,
    IonicModule.forRoot(MyApp),
    HttpModule,
    NgCalendarModule,
    AngularFireModule.initializeApp(firebaseConfig),
    AngularFireDatabaseModule, //This is included in imports

    ...

The error occurs when attempting to navigate to a specific page within my application, particularly one that involves angularfire2 requests. It is worth mentioning that I upgraded these requests to adhere to the new angularfire2 5.0 code standards, hence the confusion surrounding this error. To keep things running smoothly, I opted to use angularfire2/database-deprecated temporarily so that all requests can function without any prior adjustments. Any assistance or insights on this matter would be greatly appreciated. Thank you.

Answer №1

Start by including the necessary import:

import { AngularFireDatabase, AngularFireDatabaseModule } from 'angularfire2/database';

Next, make sure to add AngularFireDatabase to the providers array:

providers: [
    StatusBar,
    SplashScreen,
    AngularFireDatabase,
    {provide: ErrorHandler, useClass: IonicErrorHandler},
  ]
