Unable to use collectionGroup query in AngularFirestore

Question

I am using AngularFirestore and Ionic 3. I want to use the collectionGroup query feature of Firebase but I am not getting this option either by importing AngularFirestore or doing import * as firebase from 'firebase/app';

this.afs.collectionGroup() is not available.

Answer 1

The AngularFire2 documentation shows how to use Collection Group Queries.

If that doesn't work for you, ensure you're using AngularFire2 version 5.2 or later.
