Is there any cost efficient way to find the number of docs in a collection in firestore

I'm new to firebase and I'm trying to integrate it into my vuejs project. if I just want the number of docs in a collection instead of the actual docs, i read all the docs and use snapshot.size() to find the number. Is this cost-efficient? If not is there a better way to approach it?

As the docs stays, this is what snapshot.size() is ment for. So you can go ahead with it.

Yes it is, you can implement distributed counters as explained in the official documentation of distributed counters.

As a personal hint, don't store this kind of counters in Cloud Firestore, because every time you increase or decrease the counter will cost you a read or a write operation. Host this counter in Firebase realtime database "at almost no cost".
