Can I get the generated ID for a document created with batch().set using Firestore?

Question

Is there a way that I can get the auto-generated ID for a document created as part of a batch using Firestore?

Answer 1

I had similar issue, And I thing there were changes at the API of firestore.

I was getting an error for code like :

const postsRef = db.collection('posts').doc(postKey);
batch.set(postsRef, {title: 'Hello Again, World'});

The change I found that was necessary is to take the ref of the doc object:

const postsRef = db.collection('posts').doc(postKey).ref;

I hope this helps you all !
