Angular2 Routing: import submodule with routing + making it prefixed

Question

I have a main module and some submodules. And I want to specify some not trivial routing between them.

I\'d prefer defining the routes of a submodule within the sub

Answer 1

Playing with this Routing stuff I just found a clean way I would like to share, to handle the routes of submodules with no headaches and love Angular even more. Taking the OP case as an example, I propose you to study the following code:

Add a utility function to your CountryModule submodule, to load it dynamically from the Router and avoid a compiler warning about replacing the arrow function with a reference to an exported function:

@NgModule({
  imports: [
    ...
    RouterModule.forChild([
      { path: 'country', pathMatch: 'full', redirectTo: 'list' },
      { path: 'country/list', component: CountryListComponent },
      { path: 'country/create', component: CountryCreateComponent },
    ])
  ],
  declarations: [ ... ],
  exports: [
    RouterModule,
  ],
})
export class CountryModule {}

export function CountryEntrypoint() {
  return CountryModule;
}

Now you can import that Entrypoint into your parent module where you want to place the routes:

@NgModule({
  imports: [
    ...
    RouterModule.forRoot([
      { path: '', pathMatch: 'full', component: HomeComponent },
      { path: 'settings', loadChildren: CountryEntrypoint }
    ]),
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

And there you go! You can now reach your submodule components with settings/country/list and settings/country/create.

WARNING

Be careful to not import the CountryModule into your parent module's @NgModule, because it will override the routes outside the settings path. Let the router do the job.

Enjoy!
