LoggedInOutlet angular2 authentication - Router v3.0.0-alpha8 - Where is ComponentInstruction?

Question

I am using code like this to extend RouterOutlet and create app wide authentication and route protection

import {Directive, Attribute, ViewContainerRef, DynamicC

ComponentInstruction has been deprecated. In the current RC4 version of Angular2, this class has been listed under reouter-deprecated. With RC5 coming in, this package would be dropped.

RouterOutlet has changed a lot over time and to make your class LoggedInRouterOultet work, you have to use CanActivate interface.

You can do something like this:

Have an injectable service like LoggedInActivator shown here:

import { Injectable } from '@angular/core';
import { Router, CanActivate } from '@angular/router';
import { LogInService } from './login.service';

@Injectable()
export class LoggedInActivator implements CanActivate {
  constructor(private loginService: LogInService) {}

  canActivate() {
    return this.loginService.isLoggedIn();
  }
}

Add canActivate and map it to LoggedInActivator on component while defining route:

{ path: 'home', component: HomeComponent, canActivate: [LoggedInActivator] }

I hope this helps!
