Heres my router config:
import { RouterConfig } from '#angular/router';
...
export const AppRoutes : RouterConfig = [
{
path: '',
redirectTo: 'myview',
pathMatch: 'full'
},
{
path: 'myview',
component: ViewComponent,
children: [{
path: 'hello',
component: HelloComponent
}]
},
];
When I try to load the page I get the following error:
EXCEPTION: Error: Uncaught (in promise): Error: Cannot match any routes: ''
However, when I make the child route a sibling, like this:
export const AppRoutes : RouterConfig = [
{
path: '',
redirectTo: 'myview',
pathMatch: 'full'
},
{
path: 'myview',
component: ViewComponent
},
{
path: 'hello',
component: HelloComponent
}
];
I am able to load the page fine without any errors. What am I doing wrong?
Because the way you have designed it is on initial load it is landing on ViewComponent component but ViewComponent has child so have to redirect to inner component.
You need to add one more route to children routes which will redirect '' to hello component.
export const AppRoutes: RouterConfig = [
{ path: '', redirectTo: 'myview', pathMatch: 'full'},
{ path: 'myview', component: ViewComponent,
children: [
{ path: '', pathMatch: 'full', redirectTo: 'hello' }, //added redirection to hello
{ path: 'hello', component: HelloComponent }
]
}
];
Note: Make sure you have <router-outlet></router-outlet> in myview component HTML so that child route view can be shown
correctly.
You are not using any route for '' in your RouterConfig.
As after redirect the new path will be https://yourdomain/myview/. And for this you have only created https://yourdomain/myview/hello route in routeCofig
I have created an app in angular 2. You can check the source here on Github.
Just add following line to your children path array:
{path: '', component: HelloComponent }
Check hero.routes.ts and dragon.routes.ts files they will help you understand routing more clearly. Hope it will help. Thank you.

i have a left side navigation in home component, the navigation dropdown is not working in one of the routing module (admin-routing.module.ts).
the navigation is working in app-routing.module.ts "path:'home'"
the component file is same in the two routing modules
i am new in angular, i am using angular 14v
i have a component name with "home"
i used two routing
app-routing.module.ts
admin-routing.module.ts
This goes inside app-routing.module.ts
const routes: Routes =
[
{ path: 'login', component: LoginComponent },
{ path: 'forgot-password', component: ForgotPasswordComponent },
{ path: 'not-found', component: NotFoundComponent },
{ path: '', redirectTo: 'login', pathMatch: 'full' },
{
path: 'admin',
loadChildren: () =>
import('./modules/admin/admin.module').then((m) => m.AdminModule)
},
{path:'home', component:HomeComponent},
{ path: '**', component: NotFoundComponent },
];
This goes inside admin-routing.module.ts
const routes: Routes = [
{
path: '',
component: HomeComponent,
children: [
{ path: '', redirectTo: 'dashboard', pathMatch: 'full'},
{ path: 'dashboard', component: DashboardComponent }
]
}
];
i also added the script file path in angular.json
the navigation dropdown and toogle is not working in admin-routing.module.ts's "home path"
i hosted these files in my server
working navigation link is http://angular.byteinnovations.in/home
this navigation is not working http://angular.byteinnovations.in/admin/home
As i see in your routing
const routes: Routes = [
{
path: '',
component:HomeComponent,
children:
[
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'home', component: HomeComponent }
]
}
];
You are using HomeComponent two times can you check and do it in this way on your adminRouting Module
const routes: Routes = [
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'home', component: HomeComponent }
]
In my routes file I am trying to achieve the following.
const routes: Routes = [{ ...
{ path: '', component: MainComponent, children: [
{ path: 'routeA', component: ComponentA },
{ path: 'routeA/subA', component: ComponentAA},
{ path: 'routeA/subB', component: ComponentAB},
{ path: 'routeA/**', redirectTo: 'routeA'}
]}, ...}
The intention being that routeA/ will redirect back to routeA, but the above code doesnt achieve the intended effect.
How can i set as default a child state with ui-router and angular.io?
I have a section about, with some child-states. What i want to do is that when i go in the about section, by default it renders the first child state.
You can redirect for default child route like this:
{
path: 'course',
component: CourseComponent,
children: [
{
path: 'list',
component: CourseListComponent
},
{
path: 'taking',
component: TakingCourseComponent
},
{
path: '**',
redirectTo: 'list', // this work like as default custom route.
pathMatch: 'full'
}
]
},
I have a few components that are all under account.
Username
Password
Profile
...
I want to have a parent component like how the app-component works, with a <router-outlet></router-outlet>, so that the main html of the parent component never changes but the contents of the <router-outlet></router-outlet>.
How do I go about this?
You can define your component route like
const appRoutes: Routes = [
{ path: '/main', component: appComponent },
{ path: 'login/:id', component: LoginComponent },
{
path: 'users',
component: userListComponent,
data: { title: 'User List' }
},
{ path: '',
redirectTo: '/users',
pathMatch: 'full'
},
{ path: '**', component: PageNotFoundComponent }
];
#NgModule({
imports: [
RouterModule.forRoot(
appRoutes,
{ enableTracing: true } // <-- debugging purposes only
)
// other imports here
],
...
})
export class AppModule { }
then in your appComponent.html
<h1>your html</h1>
<router-outlet></router-outlet>
<h1>your html</h1>
https://angular.io/guide/router
You can use children or loadChildren(For Lazy Loading) concepts.
export const AppRoutes:Routes = [
{path: 'account', component: AccountComponent, children: [
{path: 'login', component: LoginComponent},
{path: 'profile', component: ProfileComponent}
]
In AccountComponent, you can add all common APIs and logic
In AccountComponentTemplate, add <router-outlet></router-outlet>
Use Angular Modularization concept for better maintenance.
Define your routes something like this:
const appRoutes: Routes = [
{ path:"", component: HomeComponent},
{ path:"accounts", component: AccountComponent, children:[
{ path:"user", component: UserComponent},
{ path:"password", component: PasswordComponent},
{ path:"profile", component: ProfileComponent}
]},
];
Define a <router-outlet> at root level as well as at child level. For child you can define it inside AccountComponent.html file.
You can follow something like this, that will help you in achieving what you require.
app.routing.ts
export const AppRoutes: Routes = [{
path: '',
component: PARENTcomponentName1,
children: [
{path: 'PATH1', loadChildren: 'MODULE_PATH'}
//more path
]},
{
path: '',
component: PARENTcomponentName2,
children: [
{path: 'PATH#', loadChildren: 'MODULE_PATH'},
]}}]
So I have an app with multiple modules that has routes properly put in place, and each module has it's own routes. Everything works fine, until I try to implement lazy loading.
Previous State:
example module
export const EXAMPLE_ROUTES: Routes = [
{ path: 'new', component: AddOpportunityComponent },
{ path: ':id', component: OpportunityProfileComponent,
children: [
{
path: 'edit/sdg-info', component: SdgInfoComponent
}
]}
];
I import this EXAMPLE_ROUTES in example module
Now I have root level routing as
const APP_ROUTES: Routes = [
{ path: '', component: HomeComponent},
{ path: 'search', component: SearchComponent },
{ path: 'example', component: ExampleComponent, children: [...EXAMPLE_ROUTES], canActivate: [AuthGuard, OnboardedGuard] },
];
export const appRouting = RouterModule.forRoot(APP_ROUTES, {enableTracing: true});
With this setup it works fine
After trying to have lazy loading
example module
const EXAMPLE_ROUTES: Routes = [
{ path: 'new', component: AddOpportunityComponent },
{ path: ':id', component: OpportunityProfileComponent,
children: [
{
path: 'edit/sdg-info', component: SdgInfoComponent
}
]}
];
export const exampleRouting = RouterModule.forChild(EXAMPLE_ROUTES);
and app routing becomes
const APP_ROUTES: Routes = [
{ path: '', component: HomeComponent},
{ path: 'search', component: SearchComponent },
{ path: 'example', loadChildren: './example/example.module#ExampleModule', canActivate: [AuthGuard, OnboardedGuard] }
];
export const appRouting = RouterModule.forRoot(APP_ROUTES, {enableTracing: true});
The problem I'm facing is, the example route works fine, now the /search route breaks, as the router for some reason tries to match it with opportunity route (path: ':id')
What might be going wrong here?
This issue can occoure when you first implement your FeatureModule in your RootModule and after a given time you decide you want to load this FeatureModule lazy via loadChildren and you forgot to remove FeatureModule from your imports in your RootModule.
In your case your Routing Configuration will look something like this after compilation (PSEUDO-CODE):
const Routes_CONFIG = [
{ path: '', component: HomeComponent},
{ path: 'search', component: SearchComponent },
{ path: 'example', loadChildren: './example/example.module#ExampleModule', canActivate: [AuthGuard, OnboardedGuard] }
{ path: 'new', component: AddOpportunityComponent },
{ path: ':id', component: OpportunityProfileComponent,
children: [
{ path: 'edit/sdg-info', component: SdgInfoComponent }
]
}
]
In your case, when you just enter /search you will match :id OpportunityProfileComponent. That's because the router accepts the first route that matches a navigation request path.
