getCountFromServer not supported

[goleary]

This was released in 9.11.0 on Oct 6th:

Added getCountFromServer() (getCount() in the Lite SDK), which fetches the number of documents in the result set without actually downloading the documents.

I'd love to be able to use this in React Native Firebase

getCount was added I think in v16.1 here, it is up and running

Got it. I searched through the docs and found nothing, and also searched the repo and found nothing for getCountFromServer.

Digging through the code I've found the PR where it was added.

Curious why collectionRef.count() was the chosen syntax? The firebase-js sdk uses getCountFromServer() which makes it clear why one would want to use this method (docs are not needlessly transmitted to the client).

Does .count() behave the same?

count() behaves the same, In this case I chose to mirror the work done on FlutterFire (also done by Invertase...) I didn't realize we deviated from the JS API. Something to look in to - I'll reopen it just for naming resolution, perhaps we answer to both APIs...
