Angular2 router (@angular/router), how to set default route?

V2.0.0 and later

See also see https://angular.io/guide/router#the-default-route-to-heroes

RouterConfig = [
  { path: '', redirectTo: '/heroes', pathMatch: 'full' },
  { path: 'heroes', component: HeroComponent,
    children: [
      { path: '', redirectTo: '/detail', pathMatch: 'full' },
      { path: 'detail', component: HeroDetailComponent }
    ] 
  }
];

There is also the catch-all route

{ path: '**', redirectTo: '/heroes', pathMatch: 'full' },

which redirects “invalid” urls.

V3-alpha (vladivostok)

Use path / and redirectTo

RouterConfig = [
  { path: "https://stackoverflow.com/", redirectTo: 'heroes', terminal: true },
  { path: 'heroes', component: HeroComponent,
    children: [
      { path: "https://stackoverflow.com/", redirectTo: 'detail', terminal: true },
      { path: 'detail', component: HeroDetailComponent }
    ] 
  }
];

RC.1 @angular/router

The RC router doesn’t yet support useAsDefault. As a workaround you can navigate explicitely.

In the root component

export class AppComponent {
  constructor(router:Router) {
    router.navigate(['/Merge']);
  }
}

for other components

export class OtherComponent {
  constructor(private router:Router) {}

  routerOnActivate(curr: RouteSegment, prev?: RouteSegment, currTree?: RouteTree, prevTree?: RouteTree) : void {
    this.router.navigate(['SomeRoute'], curr);
  }
}
