Angular 7 Child Routes import Component using modules

Question

I’m trying to set some daughter routes in my angular application 7 but they don’t work, I have the following scenario:

I own a base-home.component and a home.component, I encapsulated the two Components into specific modules of each, base-home.module and home.module, imported the two modules in the app.module, and sevens in the app-routing.module a route '/' who calls the base-home.component, and a daughter route '/home' who calls the home.component, but it does not load the page, but if I import the Components directly on app.module instead of importing the modules they works, follows how are the files:

// app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

import { HomeModule } from './home/home.module';
import { BaseHomeModule } from './base-home/base-home.module';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    CommonModule,
    AppRoutingModule,
    BaseHomeModule,
    HomeModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

// app-routing.module.ts

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

import { HomeComponent } from './home/home.component';
import { BaseHomeComponent } from './base-home/base-home.component';

const routes: Routes = [
  {
    path: '',
    component: BaseHomeComponent,
    children: [
      {
        path: 'home',
        component: HomeComponent 
      }
    ]
  }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

// base-home.module.ts

import { NgModule } from '@angular/core';

import { BaseHomeComponent } from './base-home.component';

@NgModule({
  declarations: [
      BaseHomeComponent
  ],
  exports: [
      BaseHomeComponent
    ]
})
export class BaseHomeModule {}

// home.module.ts

import { NgModule } from '@angular/core';

import { HomeComponent } from './home.component';

@NgModule({
  declarations: [
      HomeComponent
  ],
  exports: [
      HomeComponent
    ]
})
export class HomeModule { }

That way up it doesn’t work, but if I care the base-home.component direct no app.module it works, that way:

// app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

import { HomeModule } from './home/home.module';
import { BaseHomeComponent } from './base-home/base-home.component';

@NgModule({
  declarations: [
    AppComponent,
    BaseHomeComponent
  ],
  imports: [
    BrowserModule,
    CommonModule,
    AppRoutingModule,
    HomeModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Does anyone know how I can make Child Routes work by importing only modules with the encapsulated Components without having to import the Component directly on app-module ?

Answer 1

In his app.module.ts try to replace the attribute 'Component' with 'loadChildren', leaving something like:

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

import { BaseHomeComponent } from './base-home/base-home.component';

const routes: Routes = [
  {
    path: '',
    component: BaseHomeComponent,
    children: [
      {
        path: 'home',
        loadChildren: './home/home.module#HomeModule', // <<<<<<<
      }
    ]
  }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

By directly referencing the module path you do not need to import nor the HomeModule nor the HomeComponent in his AppModule.
