Issue with Angular router failing to load the correct component

As a novice with Angular, I have the following routes set up.

app.routing.module.ts

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { FrameComponent } from './ui/frame/frame.component';
import { NotFoundComponent } from './common/not-found/not-found.component';

const routes = [
  {
    path: 'login',
    loadChildren: 'src/app/login/login.module#LoginModule'
  },
  { 
    path: 'dashboard',
    component: FrameComponent,
    loadChildren: 'src/app/dashboard/dashboard.module#DashboardModule'
  },

  {
      path: "**",
      component: NotFoundComponent,
  }

];

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

dashboard.routing.module.ts

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { OverviewComponent } from '../overview/overview.component';


const routes = [
  { 
    path: '',
    children:[
      {
        path: 'overview',
        component: OverviewComponent,
        //outlet: 'dashboard-inside'
      }
    ]
  },
];

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

When attempting to navigate to /dashboard, the FrameComponent from the AppRoutingModule loads correctly. However, when trying to navigate to /dashboard/overview, the NotFoundComponent is displayed instead of the desired OverviewComponent from the secondary router.

I am still new to Angular and would appreciate any guidance on what I may be missing.

Answer №1

It seems like there may be an issue with how your routes are defined.

{ 
    path: 'dashboard',
    component: FrameComponent,
    loadChildren: 'src/app/dashboard/dashboard.module#DashboardModule'
  }

The code snippet above is not implementing lazy loading properly - instead of loading the children, it is only loading the FrameComponent, which Angular handles automatically.

If your FrameComponent is a part of the AppModule, you can simply remove the loadChildren property from the path, and Angular will handle the routing for you.

If it is not part of the AppModule, you can try the following approach:

app-routing.module.ts

 { 
    path: 'dashboard',
    loadChildren: 'src/app/dashboard/dashboard.module#DashboardModule'
  }

Load another module from the path and then load the desired component from that module.

dashboard-routing.module.ts

{ 
    path: '',
    component: FrameComponent,
    children:[
      {
        path: 'overview',
        component: OverviewComponent,
        //outlet: 'dashboard-inside'
      }
    ]
  }

Ensure that you have declared the FrameComponent inside the DashboardModule, which will allow you to load the desired route.

Now, if the path is /dashboard, Angular will load the dashboard module and look for the path '' after /dashboard, loading the FrameComponent. Then, when accessing /dashboard/overview, the child route will be loaded and the OverviewComponent will be displayed.

Hopefully, these adjustments will resolve the issue. Feel free to reach out if you have any questions. Happy coding!

One solution is to relocate component: FrameComponent from the dashboard route to the dashboard routing module.

  { 
    path: 'dashboard',
    loadChildren: 'src/app/dashboard/dashboard.module#DashboardModule'
  },


  { 
    path: '',
    component: FrameComponent,
    children:[
      {
        path: 'overview',
        component: OverviewComponent,
      }
    ]
  },

Furthermore, it may be beneficial to import your modules in the core module.

Answer №3

There is a mistake in the definition found in the dashboard.routing.module.ts file.

Consider implementing the following corrections:

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { OverviewComponent } from '../overview/overview.component';


const routes = [
  { 
    path: 'overview', // <-- should be in root.
    component: OverviewComponent,
  },
];

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