Answer 1

For angular6+

    this.shirtCollection = afs.collection('shirts');
    this.shirts = this.shirtCollection.snapshotChanges().pipe(
        map(actions => {
        return actions.map(a => {
            const data = a.payload.doc.data() as Shirt;
            const id = a.payload.doc.id;
            return { id, ...data };
        });
        })
    );
