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: AngularFirestoreCollection<Races> = this.afs.collection('races'); return racesCollection.valueChanges(); 

I do get my documents list perfectly, however there is no doc id with them.

How can I retrieve it for each document ?

Answer 1

For angular 8 and Firebase 6 you can use the option id field

      getAllDocs() {            const ref = this.db.collection('items');            return ref.valueChanges({idField: 'customIdName'});       } 

this adds the Id of the document on the object with a specified key (customIdName)
