AngularFirestore Cannot Find FirebaseDocumentStream

import { Component } from '@angular/core';
import { AngularFireDatabase } from 'angularfire2/database';
import { Observable } from 'rxjs/Observable';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {
  data: FirebaseObjectObservable<any>;
  constructor(db: AngularFireDatabase) {
    this.data = db.object('data').valueChanges();
  }
}

Every time I attempt to compile my code, I encounter the following error message:

Error: Cannot find name 'FirebaseObjectObservable'.

I assumed that this was a part of the angularfire2/database module. What might I be missing?

Answer №1

The reason for encountering this error is due to its deprecation and non-existence in version 5. The official angularfire2 documentation provides insight on this matter:

With the release of AngularFire 5.0, major changes have been made to the AngularFireDatabase module. The previous FirebaseListObservable and FirebaseObjectObservable have been replaced with a more versatile service API.

To resolve this issue, it is recommended to transition to using AngularFireObject. For further guidance, refer to the official documentation Upgrading to AngularFire 5.0.
