Angular 2 routing redirect to with child routes

I am a newbie in Angular 2. I want to create isolated modules for every part of my app. For example I created the AuthModule with default component - AuthComponent which contain a router-outlet for his child components (SignIn or SignUp). So I want to realise the following scenario:

1. When navigate to / - root off app - redirect to /auth
2. After redirect to /auth - load AuthComponent with router outlet
3. After AppComponent loaded - load default sign-in component via redirecting to /auth/sign-in

But when I going to localhost/ I get redirect to /auth what I want, but the next redirect to sign-in doesn't appear.

My code: app.routing

const routes: Routes = [
  {
      path: '', 
      redirectTo: '/auth', 
      pathMatch: 'full'
  }
];

export const appRouting: ModuleWithProviders = RouterModule.forRoot(routes);

auth.routing

const routes: Routes = [
  {
    path: 'auth',
    component: AuthComponent,
    children: [
      {
         path: '', 
         redirectTo: 'sign-in', 
         pathMatch: 'full'
      },
      {
         path: 'sign-in', 
         component: SignInComponent
      }
    ]
  },

];

export const authRouting: ModuleWithProviders = RouterModule.forChild(routes);

auth.component.html

<div class="container">
    <h1>Auth component</h1>
    <router-outlet></router-outlet>
</div>

Result:

Environment @angular/cli: 1.0.0-rc.2 node: 7.7.1 os: win32 x64

Solution 1:

I have been the same problem. It seems an Angular tricks: If you remove leading slash in 'redirectTo' field, your application will be redirected successfully to auth/sign-in.

Use this in app.routing:

const routes: Routes = [ 

    {path: '', redirectTo: 'auth', pathMatch: 'full'}, 

];

‘redirectTo’ value starts with a ‘/’ = absolute path

‘redirectTo’ value starts without a ‘/’ = relative path

P.S My opinion that your structure more correctly then YounesM's one. Parent module can't keep children routes: "app" module don't know that "auth" module have children module "sign-in".

Solution 2:

On auth.routes

const routes: Routes = [
  {
    path: "auth",
    redirectTo: "auth/sign-in"
  },
  {
    path: "auth",
    component: AuthComponent,
    children: [{ path: "sign-in", component: SignInComponent }]
  }
];

Solution 3:

So, what it seems to happen is that when you redirectTo:'auth' it tries to load the '' children's component and since it does not have any component the router-outlet is empty.

Now it seems like {path: '', redirectTo: 'sign-in', pathMatch: 'full'} doesn't have any other purpose then redirecting to sign-in so you can simply redirect to /auth/sign-in instead.

app.routes

const routes: Routes = [
  {path: '', redirectTo: '/auth/sign-in', pathMatch: 'full'}
];
export const appRouting: ModuleWithProviders = RouterModule.forRoot(routes);

auth.routes

const routes: Routes = [
  {
    path: 'auth',
    component: AuthComponent,
    children: [
      {path: 'sign-in', component: SignInComponent}
    ]
  },

];

or have a component in your '' path instead of redirecting.

app.routes

const routes: Routes = [
  {path: '', redirectTo: '/auth', pathMatch: 'full'}
];
export const appRouting: ModuleWithProviders = RouterModule.forRoot(routes);

auth.routes

const routes: Routes = [
  {
    path: 'auth',
    component: AuthComponent,
    children: [
      {path: '', component: SignInComponent}
    ]
  },

];

Solution 4:

It's quite simple:

const routes: Routes = [
    { path: '', redirectTo: '/auth/signin', pathMatch: 'full' },
    { path: 'auth', component: AuthComponent, 
        children: [
            { path: 'signup', component: SignupComponent }, 
            { path: 'signin', component: SigninComponent }, 
            { path: 'logout', component: LogoutComponent }
        ]
    },
    { path: '**', redirectTo: '/auth/signin', pathMatch: 'full' }
];
