Reload app

When user enter into my app for the first time, because he is not login with firebase he goes directly to a tabs page (this.rootPage = “login-tabs”).

in login tabs I have 2 tabs (sing-in-page,sign-up-page).

after the user sign in or signup I want the app to reload completely (with splash screen).
and now because he is login, he goes to main tabs (this.rootPage = “main-tabs”).

   firebase.auth().onAuthStateChanged(user => {
      if (user) {
        this.rootPage = "login-tabs"
      } else {
       this.rootPage = "main-tabs"

Somebody know the best practice to do it ?

I ready try'localhost:8080', { openExternal:false });


every time when I try something it seems that the main-tabs loaded but it keep show the login-tabs
