Hello All,

I have a problem with child routes on Angular 2. I have defined a routing as follows,

accounts-routing.module.ts

import { NgModule } from ‘@angular/core’;
import { RouterModule, Routes } from ‘@angular/router’;

import { AccountsComponent } from ‘./accounts.component’;
import { ForgotComponent } from ‘./forgot/forgot.component’;
import { RegisterComponent } from ‘./register/register.component’;
import { LoginComponent } from ‘./login/login.component’;

const accountsRoutes: Routes = [
{
path: ‘’,
component: AccountsComponent,
children: [
{
path: ‘’,
component: AccountsComponent
},
{
path: ‘forgot’,
component: ForgotComponent
},
{
path: ‘login’,
component: LoginComponent
},
{
path: ‘register’,
component: RegisterComponent
}
]
}
];

@NgModule({
imports: [
RouterModule.forChild(accountsRoutes)
],
exports: [
RouterModule
]
})

export class AccountsRoutingModule {}

And the following one is my main routing module.

app-routing.module.ts

import { NgModule } from ‘@angular/core’;
import { Routes, RouterModule } from ‘@angular/router’;
import { Meteor } from ‘meteor/meteor’;

import { HomeComponent } from ‘./home/home.component’;

const appRoutes: Routes = [
{
path: ‘’,
component: HomeComponent
},
{
path: ‘home’,
component: HomeComponent
},
{
path: ‘accounts’,
loadChildren: ‘client/imports/app/accounts/accounts.module#AccountsModule’
}
];

export const ROUTES_PROVIDERS = [{
provide: ‘canActivateForLoggedIn’,
useValue: () => !! Meteor.userId()
}];

@NgModule({
imports: [
RouterModule.forRoot(appRoutes)
],
exports: [
RouterModule
]
})

export class AppRoutingModule {}

Routing is perfectly working while I am not using child routes.

<a routerLink="/">No Route</a>
<a routerLink="/home">Home Route</a>
<a routerLink="/accounts">Accounts Route</a>

But when I route to accounts which has a child route I get the following error.

As I know we all use commonjs as module not systemjs. Why do I get this error any one got any idea?

Please help me :frowning:

Thanks in advance.

Did you ever resolve this issue? I’ve been working at it this weekend and have come to the conclusion this can’t be done. I tried a few hacks with using systemJS but in a nutshell the issue is that you can’t lazy load modules with Meteor due to the way it scans and eagerly loads ALL modules at startup. I’ve been considering a few other places to ask but from what I can tell Meteor implementations are limited to a single router at the core, or in the very best adding child Route objects and importing those into the core router which only serves the purpose of keeping the core router file a bit smaller.
