Encountering a problem with loading a module lazily (Module not found)

Despite my best efforts, I am struggling to implement lazy loaded modules in my project. It seems like I am missing a key element that is preventing me from loading modules on demand.

This is how my project structure looks:

app
 -users
  -homeComponent
  -signupComponent 
  -users.routing.module.ts
  -users.module.ts
 -list
  -createListComponent
  -dashboardComponent 
  -list.routing.module.ts
  -list.module.ts

users-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { SignupComponent } from './signup/signup.component';

const routes: Routes = [
  {
    path: "",
    component: HomeComponent
  },
  {
    path: "/signup",
    component: SignupComponent
  }

];

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

app-routing.module.ts

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

const routes: Routes = [
  {
    path: 'signup',
    loadChildren: './app/users/users.module#UsersModule',
  },
];

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

Even after adding the correct relative path to my loadChildren tag, I continue to encounter an error stating "cannot load module". Despite searching on multiple websites for solutions, it feels like I am overlooking a fundamental aspect here.

I would greatly appreciate any assistance or guidance on this issue.

  1. Integrate the users component within the users module for enhanced functionality.
  2. The users component serves as a container where various child components will load seamlessly.
  3. Include the
    <router-outlet></router-outlet>
    directive in the app component to enable routing functionality.

users-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { SignupComponent } from './signup/signup.component';
import { UsersComponent } from './users.component';

const routes: Routes = [
  {
    path: '',
    component: UsersComponent, // main component for users module
    children: [ // defining child routes for user module
      {
        path: 'signup',
        component: SignupComponent,
      },
      {
        path: 'home',
        component: HomeComponent,
      },
    ]
  }
];

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

Answer №2

New Lazy Loading Syntax implementation now utilizes promises and observables, Give this a try:

const routes: Routes = [
  {
    path: 'signup',
    loadChildren: () => import('./app/users/users.module').then(u => u.UsersModule)
  },
];

Answer №3

It appears that there may be an issue with the way your route configuration is set up.

const routes: Routes = [
  {
    path: "",
    component: HomeComponent
  },
  {
    path: "/signup",
    component: SignupComponent
  }

];

In this setup, the SignupComponent route object will not be reached because Angular router evaluates the configuration arrays sequentially and stops at the first match (in a DFS manner). Since every possible route matches "", it starts searching from there.

To address this issue, you can consider adding the pathMatch: 'full' option:

const routes: Routes = [
  {
    path: "",
    component: HomeComponent,
    pathMatch: 'full',

  },
  {
    path: "/signup",
    component: SignupComponent
  }

];

Another approach would be to keep the HomeComponent route at the end of the array as is.

Functional code available at stackblitz

To achieve the desired outcome, simply follow these instructions - omit the path value for lazy loaded modules and leave it empty.

// users-routing.module.ts
const routes: Routes = [
  {
    path: '', // keep empty
    component: SignupComponent,
  },
];
<!-- app.component.html -->
<p> homepage functioning as intended </p>
<router-outlet></router-outlet>
