Firestore Getting documents id from collection

Question

I\'m trying to retrieve my documents with id but can\'t figure it out.
Currently I retrieve my documents like this :

const racesCollection: AngularFir

For document references, not collections, you need:

// when you know the 'id'

this.afs.doc(`items/${id}`)
  .snapshotChanges().pipe(
    map((doc: any) => {
      const data = doc.payload.data();
      const id = doc.payload.id;
      return { id, ...data };
    });

as .valueChanges({ idField: 'id'}); will not work here. I assume it was not implemented since generally you search for a document by the id...
