Firebaseui-web: Event that the user is just registered (and first time sign-in with Auth provider)?

[mcialexliu]

Is there any event being emitted so that we know the user is just added to firebase auth?

At the moment, i can only keep it in database and when someone login, check if the uid is created in database, which is quite clumsy for just checking for a single event that is obviously can be emitted.
I believe it is common that an apps need to have their own specific user profile.

Or is there any simple way to implement?

Currently there is another way to track that via Firebase Functions.

I'd like to be able to do this as well. I'd like to show new sign ups an onboarding experience, and hide that experience from existing users.

This issue hasn't been updated but signInSuccessWithAuthResult will provide additional user info regarding whether the user is new or existing. You can check:

var isNewUser = authResult.additionalUserInfo.isNewUser;

Awesome, thanks! @bojeil-google
