firestore security rule check if a field is an integer

I am wondering how do I check if a field is an integer or not. I know that we are able to convert a field entry to an integer with int(request.resource.data[field]), but is there a way to check if request.resource.data[field] is an integer, return true if it is, and false it isn't?

You can check for type with the is operator.

So:

request.resource.data[field] is int

Or

request.resource.data.field is int

I highly recommend checking out Doug's video on Data types and global objects in Firebase security rules, specifically the section on checking types.
