Function setUserId

Specify a user identifier which will be visible in the Firebase Crashlytics console.

It is recommended for privacy purposes that this value be a value that's meaningless to a third-party observer; such as an arbitrary string that ties an end-user to a record in your system e.g. a database record id.

Example

const auth = getAuth();
const crashlytics = getCrashlytics();
// Custom user id
await setUserId(crashlytics, '123456789');
// Firebase auth uid
await setUserId(
 crashlytics,
 auth.currentUser.uid
);
