Do I need to get the User Token each and every time from the Firebase

Question

I have put the below method on the Auth service and get the currentUserIdToken and store it as a global variable. Is this approach has any issues? i.e. will it expire this token quickly or something like that? Or do I need to get this each and every time from the Firebase? I have done this kind of approach since I can avoid unnecessary calls to the db. Any thoughts?

init(): void {
    this.afAuth.authState.subscribe(async (user: firebase.User) => {
      if (user) {
        this.currentUserUid = user.uid;
      this.currentUserIdToken = await this.afAuth.auth.currentUser.getIdToken(true); // Here

        this.onboardingService.currentUserUid = this.currentUserUid;


    });
  }

The token will expire every hour. Instead of making a call to getIdToken() repeatedly, you can listen for changes to it using onIdTokenChanged() and provide a callback to receive the new token immediately when it's automatically refreshed by the client SDK.

Can I have an `AngularFireAuth` method for it? It seems there is no such thing no? – Sampath Jan 17 '20 at 15:51
Did you try searching the documentation? It's just a wrapper around the core Firebase library. If you don't find it, then file an issue on the angularfire GitHub. – Doug Stevenson Jan 17 '20 at 15:53
Yes, it has `this.afAuth.idToken` – Sampath Jan 17 '20 at 16:00
