angular 2 - redirct user homepage if try access logged in page. (i need not hit components constructor)

i'm using typescript , angular2.

currently works if have no calls services in components constructor.

currently i'm using doing (but keeps hitting internal components constructor still , causing errors):

import {directive, attribute, elementref, dynamiccomponentloader} 'angular2/core'; import {router, routeroutlet, componentinstruction} 'angular2/router';  @directive({   selector: 'router-outlet' }) export class loggedinrouteroutlet extends routeroutlet {   publicroutes: any;   private parentrouter: router;    constructor(_elementref: elementref, _loader: dynamiccomponentloader, _parentrouter: router, @attribute('name') nameattr: string) {     super(_elementref, _loader, _parentrouter, nameattr);     this.parentrouter = _parentrouter;     this.publicroutes = {        '/home': true      };   }    activate(instruction: componentinstruction) {            console.log("here");       this.parentrouter.navigate(['/home']);       return super.activate(instruction);    } }

it works if internal page doesn't have in constructor.

what need @canactivate directive in front of protected component.

https://angular.io/docs/ts/latest/api/router/canactivate-decorator.html

@canactivate(() => checkauth()) export class protectedcmp {}

consider plunker (protected.component.ts )
