Auth laravel5-angular-material-starter

It's my first post on SO. Im trying Laravel-angular-material-starter (Lams) link and i have a problem with finding (in angular component) if user is authenticated. If he isen't i whant to show him login and register link. Lams us JWT Authentication. Thx for help !

In root-dir->angular->app->components->app-header->app-header.component.js i got :

 class AppHeaderController{
constructor($log,$auth,$scope){
    'ngInject';
    this.$scope = $scope;
    this.$log = $log;
    this.$auth = $auth;
}

$onInit(){
    //its not working 
    if(this.$auth==true){
        this.$scope.zalogowany = true;
        this.$log.log('yes');
    }
    else{
        this.$scope.zalogowany = false;
        this.$log.log('no');
    }
}}

export const AppHeaderComponent = {
templateUrl: './views/app/components/app-header/app-header.component.html',
controller: AppHeaderController,
controllerAs: 'vm',
bindings: {} }

and in root-dir->angular->app->components->app-header->app-header.component.html i have :

<md-content class="Page-Container DemoHeader">
<div layout="row">
    <div flex="90" flex-offset="5" class="DemoHeader-container">
        <div layout="row" layout-align="space-between">
            <a hide-xs class="DemoHeader-link md-subhead" href="#/" >DareMe</a>
            <div layout="row" layout-align="center stretch">
                <a ng-show="!zalogowany" hide-xs class="DemoHeader-link md-subhead" href="#/login" >Logowanie</a>
                <a ng-show="!zalogowany" hide-xs class="DemoHeader-link md-subhead" href="#/register" >Rejestracja</a>
            </div>
        </div>
    </div>
</div>
