Firebase Web Analytics: What is App version and how to set it

Question

Hi I have been trying the new web analytics for my firebase projects and I see an App version user property as seen below. However with some research I could not figure out how to set this property or what it really means in terms of my Firebase web app, since on web there is (AFAIK) no app version config or place to set it.

Via Help it says:

The versionName (Android) or the Bundle version (iOS).

My app is a web app...

So how can I change this "app version" ?

I read a couple of help pages such as https://firebase.google.com/docs/remote-config https://support.google.com/firebase/answer/6317486?hl=en https://support.google.com/analytics/topic/9355655?hl=en&ref_topic=9353537

Answer 1

From what I understand so far that number 8 is just the visitors/events and the panel just lucks the app version info looking very confusing.

example

So under the top app version you get the events/visits not the app version since it doesn't exist/defined.

UI could have been better

Answer 2

For web apps I believe that the property is called "app_version". Web app versions don't show up for me either in the "Top app version" view. It seems like a missing feature in Firebase Analytics. I say this because the Typescript types for firebaseApp.analytics().logEvent suggests that the eventParams can have a field called app_version.
