How to get current route custom data in angular 2?

Question

I have set up routes is like below

const appRoutes: Routes = [
  {
    path: \'login\',
    component: LoginComponent,
    data: {
      title: \'Login TTX\         


        

Answer 1

This worked for me in app.component.ts (ng 5)

 constructor(
    private router: Router,
) {

 router.events.subscribe((routerEvent: Event) => {
       this.checkRouterEvent(routerEvent);
    });
}

checkRouterEvent(routerEvent: Event): void {
    if (routerEvent instanceof ActivationStart) {
        if (routerEvent.snapshot.data.custom_data) {
            this.currentpage = routerEvent.snapshot.data['custom_data'];
            console.log('4.' + this.currentpage);
        }

    }
