Hi guys , i have a little issue, when the app first load i have a blank page before rendering any page (login or homeview) regarding the connection state of my user.
this is my code on the main view (where i handle connection state).

<App>
	<Router ux:Name="router" />


	<JavaScript>
	// parse import and initialization
	var Parse = require('parse.js')
	Parse.initialize("PARSE", "PARSE");
	Parse.serverURL = 'PARSEURL';


	// parse verify if the user is login or nothing
		var currentUser = Parse.User.current();
			if (currentUser) {
		router.goto("home");
		} else {
		router.goto("LoginView");
		}


		function goback(){
			router.goBack()
		}

		





	module.exports = {
	currentUser: currentUser,
	goback: goback
	}
	</JavaScript>

	<Navigator Transition="Standard">
