How to handle Firestore request pending state.

[thanhtutzaw]

I am preventing user's browser not to refresh when request are sending to database.
How can I know getDoc is pending or Successful.
I want to use with beforeunload event listener.
Problem is when user immediately refreshed, the pending request are all cancelled itself.
