Angular 4 Routing - All Routes are redirected to Default Route

Question

I've setup a simple routing for my angular 4 app that consists of a sidemenu created using Tetradata Covalent and Angular Material i'm using this Angular 2/4 Authentication tutorial to handle login, however all child router links are redirecting to the default page(dashboard). Any help or advice would be highly appreciated.

app.routing.ts

export const APP_ROUTES: Routes = [
  {path: 'login', component: HomeComponent},
  { path: '', redirectTo: 'mainpage', pathMatch: 'full' },
  { path: '**', redirectTo: 'mainpage' },
  {
    path: 'mainpage',
    component: MainPageComponent,
    canActivate:[AuthGuard],
    children: [
      {path: 'order', component: OrderComponent},
      {path: 'dashboard', component: DashboardComponent},
      {path: 'stock', component: StockComponent},
      {path: 'Report/sales', component: SalesComponent},
      {path: '', redirectTo: 'dashboard', pathMatch: 'full'}
      {path: '**', redirectTo: 'dashboard', pathMatch: 'full'}
    ]
  }
];

page.component.html

<td-layout>
  <td-navigation-drawer flex sidenavTitle="EzyAgric" logo="assets:logo" name="Akorion" email="info.akorion.com">
<md-nav-list>
      <a md-list-item [routerLink]="['dashboard']">
        <md-icon>dashboard</md-icon>
        Dashboard</a>
      <md-divider></md-divider>
      <h3 md-subheader>Orders</h3>
      <a md-list-item [routerLink]="['stock']">
        <md-icon>archive</md-icon>
        Stock
      </a>
      <a md-list-item [routerLink]="['order']">
        <md-icon>shopping_cart</md-icon>
        Received Orders
      </a>
  </td-navigation-drawer>
  <td-layout-nav [toolbarTitle]="getTitle()" >
    <div class="example-scrolling-content">
      <router-outlet></router-outlet>
    </div>
  </td-layout-nav>
</td-layout>

AuthGuard.ts

@Injectable()
export class AuthGuard implements CanActivate {
  constructor(private router: Router) { }

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    if (localStorage.getItem('currentUser')) {
      // logged in so return true
      return true;
    }

    // not logged in so redirect to login page with the return url
    this.router.navigate(['/login'], { queryParams: { returnUrl: state.url }});
    return false;
  }
}

console output

In your app.routing.ts where you define your routes move the wildcard line to the end after you have defined all your routes.

app.routing.ts

export const APP_ROUTES: Routes = [
  {path: 'login', component: HomeComponent},
  { path: '', redirectTo: 'mainpage', pathMatch: 'full' },
  {
    path: 'mainpage',
    component: MainPageComponent,
    canActivate:[AuthGuard],
    children: [
      {path: 'order', component: OrderComponent},
      {path: 'dashboard', component: DashboardComponent},
      {path: 'stock', component: StockComponent},
      {path: 'Report/sales', component: SalesComponent},
      {path: '', redirectTo: 'dashboard', pathMatch: 'full'}
      {path: '**', redirectTo: 'dashboard', pathMatch: 'full'}
    ]
  },
  { path: '**', redirectTo: 'mainpage' } // this needs to be after other routes
];

Since it is a wild card route angular will hit this route before hitting any other route since routes order matter.
