Firebase listener ?

[Abdelwaheb Dhouioui]

I'm really sorry for any inconvenience this may cause,

I would like to ask, is there any kind of event listener in Firebase especially for sign-in / sign-up events, this will be helpful to perform some actions as described below:

Sign-up event: when Firebase listener detect a user connection for the first time, it will trigger a method to add new user profile data in the database,

Sign-in event: when firebase listener detect a connection of an already existing user, it will trigger a method to update some field in database such as updating last connection date, this will really help administrator to delete inactive users.

 

Thank you guys,
