Official documentation has quite a lot of information about how to load angular modules lazily. [link here]
const routes: Routes = [
{
path: 'customers',
loadChildren: './customers/customers.module#CustomersModule'
},
{
path: 'orders',
loadChildren: './orders/orders.module#OrdersModule'
},
{
path: '',
redirectTo: '',
pathMatch: 'full'
}
];
This basically makes the module load when user visits /customers or /orders routes.
However, I can't figure out how do I load a module when from another module.
In my application I have these modules:
- auth
- core
- events
- flash messages
One route of my auth module (profile page) has to use ngrx store from events module.
My code looks like this:
import { Observable } from 'rxjs';
import { Component, OnInit } from '@angular/core';
import { Store } from '@ngrx/store';
import { AppState } from '../../app.store';
import { IUser } from '../auth.api.service';
import { selectUser } from '../store/auth.selectors';
import { IEvent } from '../../events/events.api.service';
import { selectAllEvents, selectIsLoading } from '../../events/store/events.selectors';
@Component({
selector: 'app-profile',
templateUrl: './profile.component.html',
styleUrls: ['./profile.component.scss'],
})
export class ProfileComponent implements OnInit {
isLoading$: Observable<boolean>;
events$: Observable<IEvent[]>;
user$: Observable<IUser>;
constructor(
private store: Store<AppState>,
) {
this.user$ = this.store.select(selectUser);
this.isLoading$ = this.store.select(selectIsLoading);
this.events$ = this.store.select(selectAllEvents);
}
ngOnInit() {
}
}
However, as you can expect this code does not work. Because ../../events is not loaded yet. How do I load the module manually? Something like:
constructor(
private store: Store<AppState>,
) {
this.user$ = this.store.select(selectUser);
this.loadModule('../../events/events.module.ts').then(() => {
this.isLoading$ = this.store.select(selectIsLoading);
this.events$ = this.store.select(selectAllEvents);
})
}
