Can I get the document key right after it is created?

Question

Right after adding this data, I would like to have the reference of this document.

it is possible?

await userCycleCollectionRef.doc().set({
    userUid,
    startDate,
    endDate,
});

Answer 1

userCycleCollectionRef.doc() returns a DocumentReference immediately, as you can see from the API documentation .

const ref = userCycleCollectionRef.doc()
await ref.set({
    userUid,
    startDate,
    endDate,
});
