Wildcard route added but still for undefined route Cannot GET /

Question

I am using Angular 6 in my project. I Added wildcard route but still iam facing the error when i go to any undefined route angular gives Cannot GET /<path> in browser.

Below is my routes, all other defined routes are working perfectly fine but wildcard not working

const AppRoutes: Routes = [
 { path: '', redirectTo: 'login', pathMatch: 'full' },
 { path: "register", component: RegisterComponent },
 { path: "login", component: LoginComponent },
 { path: "dashboard", component: DashboardComponent, canActivate: [AuthGuard] },
 { path:"backup",component:BackupComponent},
 { path: '**', component: NotFoundComponent },
];

Routes are imported as default..

imports: [
 BrowserModule,
 ReactiveFormsModule,
 NgxPaginationModule,
 .
 .
 . 
 RouterModule.forRoot(AppRoutes),
],

For some reason i could not use hash based routing

//Can not use hash base routing in my case
RouterModule.forRoot(AppRoutes, { useHash: true }),

I believe wildcard should work without hash based routing. Let me know where i am going wrong.

Answer 1

I was running the app with backend in NodeJS, running Angular and Node at same port through ng-build and node app.js When i run angular with ng serve it works fine, but not with ng build, but in production everythings seem good and wildcard working as expected.

There seems to be no issue with your defined routes. However, check this article for issue with your hash based routing.

Answer 3

This you can try to solve in 2 ways:

1. Try to change the order of parent route and wild card route such as

const AppRoutes: Routes = [
 { path: "register", component: RegisterComponent },
 { path: "login", component: LoginComponent },
 { path: "dashboard", component: DashboardComponent, canActivate: [AuthGuard] },
 { path:"backup",component:BackupComponent},
 { path: '', redirectTo: 'login', pathMatch: 'full' },
 { path: '**', component: NotFoundComponent },
];

2. Make use of redirectTo for NotFoundComponent.
