Routing for nested modules in Angular 2 RC5/Router 3 RC1

Question

Let's say I have the following setup:

employee -------+ employee.module.ts
                | employee.routing.ts
                + employee.component.ts
                |
sales ----------+ sales.module.ts
                | sales.routing.ts
                + sales.component.ts
app.module.ts
app.routing.ts
app.component.ts

and I'd like my routes to look like

employee/14/sales

So I go ahead and define these routing declarations:

app.routing.ts

...
import { AppComponent } from './app.component';

const appRoutes: Routes = [
    { path: '', component: AppComponent }
];

export const appRoutingProviders: any[] = [];
export const routing = RouterModule.forRoot(appRoutes, { useHash: true });

employee.routing.ts

...
import { EmployeeComponent } from './employee.component';

export const employeeRoutes: Routes = [
    { path: 'employee/:id', component: EmployeeComponent }  
];

export const employeeRouting = RouterModule.forChild(employeeRoutes);

sales.routing.ts

...
import { SalesComponent } from './sales.component';

export const salesRoutes: Routes = [
    { path: 'sales', component: SalesComponent }  
];

export const salesRouting = RouterModule.forChild(salesRoutes);

while my modules take this form:

app.module.ts

import { EmployeeModule } from './employee/employee.module';
import { AppComponent } from './app.component';

import {
    routing,
    appRoutingProviders
} from './app.routing';

@NgModule({
    imports: [
        ...
        EmployeeModule,
        routing
    ],
    declarations: [
        AppComponent
    ],
    bootstrap: [
        AppComponent
    ],
    providers: [
        appRoutingProviders
    ]
})

employee.module.ts

import { SalesModule } from '../sales/sales.module';
import { EmployeeComponent } from './employee.component';
import { employeeRouting } from './employee.routing';

@NgModule({
    imports: [
        SalesModule,
        employeeRouting
    ],
    declarations: [
        EmployeeComponent
    ]
})

sales.module.ts

import { SalesComponent } from './sales.component';
import { salesRouting } from './sales.routing';

@NgModule({
    imports: [
        salesRouting
    ],
    declarations: [
        SalesComponent
    ]
})
export class SalesModule {}

I can now move to

employee/14

but if I try to navigate to

employee/14/sales

I'm greeted with

Error: Cannot match any routes: 'employee/14/sales'

I can, however, enter

sales

and that works while it isn't supposed to work, so somehow all routes connect directly to / instead of building on top of each other.

What am I missing?

Answer 1

I eventually got this to work. The key idea is not to include employeeRoutes from employee.routing.ts (as that will add stuff from EmployeeModule to AppModule s declarations and result in yet another error message) but instead to create another employeeRoutes inside app.routing.ts that will lazy load EmployeeModule when navigating to a route starting with`

/employee

Here's the relevant code:

import {
    RouterModule,
    Routes
} from '@angular/router';

import { AppComponent } from './app.component';

const employeeRoutes: Routes = [
  {
    path: 'employee',
    loadChildren: 'app/employee/employee.module#EmployeeModule'
  }
];

const appRoutes: Routes = [
    { path: '', redirectTo: 'welcome', pathMatch: 'full' },
    ...employeeRoutes
];

export const appRoutingProviders: any[] = [];
export const routing = RouterModule.forRoot(appRoutes, { useHash: true });
