Firestore: How to include doc.id in doc.data() while mapping?

Answer 1

To get the doc.id you have to use snapshotChanges() in your code like this:

db.collection("Accounts").snapshotChanges().map(actions => {
  return actions.map(a => {
    const data = a.payload.doc.data();
    const id = a.payload.doc.id;
    return { id, ...data };
  });
});
