Pass enums in angular2 view templates

Create an Enum:

enum ACTIVE_OPTIONS {
  HOME = 0,
  USERS = 1,
  PLAYERS = 2
}

Create a component, be sure your enum list will have the typeof:

export class AppComponent {
  ACTIVE_OPTIONS = ACTIVE_OPTIONS;
  active: ACTIVE_OPTIONS;
}

Create a template:

<li [ngClass]="{ 'active': active === ACTIVE_OPTIONS.HOME }">
  <a routerLink="/in">
    <i class="fa fa-fw fa-dashboard"></i> Home
  </a>
</li>
