问题 I'm following the docs for Firestore here on Aggregation Queries. I couldn't help but notice that the cloud function solution wouldn't exactly work since it's not idempotent: numRatings is incremented and avgRating recomputed each time. Though this example could be made idempotent if there was also a separate document being stored for each new rating: you'd add a check if the user has already submitted a rating for the restaurant. Is there something I'm missing that makes this example

问题 When I upgrade from firebase v7.14.3 to v7.15.1 I get the following build error / typescript error: TS2339: Property 'firestore' does not exist on type 'FirebaseNamespace'.

I have probably missed the CHANGELOG, any help on how to migrate this appreciated! 回答1: I have always

I have 2 collections Events and Users. A user creates an event which goes into the Event collection, In my app users can then go onto the main page and view a list of events from the events collection. I also want to have a second page in the app a "users profile" page where users can view a list of their own events,

问题 I have a function in firebase that is intended to get all documents in a collection called history and add it to a list intended to be returned. The problem is, and I think this is because .listen() is async, the list returned is always empty. I know the data is queried correctly because I can print the doc in the forEach function, but adding to a list outside doesn't work. By the way, myStream is a snapshot of the history collection in FireStore. Does my function need to be a Future? How can
