The concept of Angular Lazy Loading involves loading modules or

I've been facing a bit of difficulty lately with lazy loading. I'm not sure if this is expected or not, and I've struggled to articulate the issue when searching for solutions.

So, I followed all the steps for setting up the lazy loaded module as usual. This includes ensuring that the app routing module is configured correctly like so:

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


const routes: Routes = [
  { 
    path: 'home', 
    loadChildren: './shared/modules/homepage/homepage.module#HomepageModule' 
  },
];

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

Next, verifying everything is set up properly with the lazy loaded module, in this case, the homepage module:

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

//~~~~ Important:
import { HomeMainComponent } from './components/home-main/home-main.component';

const homeRoutes: Routes = [
  { 
    path: '',
    component: HomeMainComponent, 
  }
]


@NgModule({
  declarations: [
    HomeMainComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(homeRoutes),
  ],
  exports: [
    HomeMainComponent 
  ]
})
export class HomepageModule { }

Currently, even without creating a redirect path for path: '', in the app router module, localhost:4200/ still loads the home module. In Augury, this is what I see:

Augury Routing Tree

Edit* Excerpt from app.module.ts:

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

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

//~~~~ Important:
import { CoreModule } from './core/core.module';
import { SharedModule } from './shared/shared.module';
import { FeaturesModule } from './features/features.module';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    CoreModule,
    SharedModule,
    FeaturesModule,
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Edit* Visual representation of the home route: https://i.sstatic.net/HMcFm.png

Edit* Refactored homepage.module.ts into its own file named homepage-routing.module.ts:

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

import { HomeMainComponent } from './components/home-main/home-main.component';


const homeRoutes: Routes = [
  { 
    path: '', 
    component: HomeMainComponent,
  },
];

@NgModule({
    declarations: [
        HomeMainComponent,
    ],
    imports: [RouterModule.forChild(homeRoutes)],
    exports: [
        HomeMainComponent,
        RouterModule]
})
export class HomepageRoutingModule { }

I have followed the correct steps, and after multiple attempts, I sense there might be an oversight on my end. Any insights on what could possibly be missing? Appreciate any assistance!

Solved**** : I realized I was using app-routing.module instead of a routing module for Shared.module. Eliminating app-routing.module and transferring those configurations to shared-routing.module resolved the issue. Much gratitude to everyone who pitched in their advice!

If you are working with newer versions, the process of lazy loading has been updated. Make sure to update your route configuration as follows:

const routes: Routes = [
  { 
    path: 'home', 
    loadChildren: () => import('./shared/modules/homepage/homepage.module').then(m => m.HomepageModule)
  },
];

Additionally, remember to include the RouterModule in your HomeModule for proper functionality:

@NgModule({
  declarations: [
    HomeMainComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(homeRoutes),
  ],
  exports: [
    HomeMainComponent,
    RouterModule 
  ]
})
export class HomepageModule { }
