AuthUser.firebaseUser delay

[kevinnammour]

Why does the AuthUser.firebaseUser takes time to be set? At first, it was null for like 2 seconds and then it is set to the current user. Why is that?

[kmjennison]

The firebaseUser property is the user from the Firebase JS SDK, which takes time to initialize on the client. It will be null before the Firebase JS SDK has initialized.

@kmjennison thank you. So if I made a firestore function that runs in a useEffect is a Page component, that might result in an error because the client SDK is not initialized yet? If yes, how can I prevent this?

[kmjennison]

Correct. You can wait for AuthUser.clientInitialized to be true (or, equivalently, for AuthUser.firebaseUser to be defined). You can use the clientInitialized property as a dependency in your hook to re-run the effect when that changes.
