The above console result is for console the routeroutlet obj.
I want to access the instance of the component which is rendered in router-outlet. how i access the instance of the component?
Don't try to use RouterOutlet as a provider. Instead add the (activate) attribute to your router-outlet tag like this:
<router-outlet (activate)="onRouterOutletActivate($event)"></router-outlet>
And then in the component containing the router-outlet element (your AppComponent class) you should implement the onRouterOutletActivate method:
public onRouterOutletActivate(event : any) {
console.log(event);
}
which will give you the route component instance in the event parameter, in this example written to the web console.
