Creating a personalized 404 page in your Angular Project and configuring a route for it

I am currently working on an Angular project that includes a component named 'wrongRouteComponent' for a custom 404 page. Whenever a user enters a non pre-defined route, the 'wrong-route.component.html' should be displayed. However, I am not sure how to achieve this.

Below is the code snippet from my 'app-routing.module.ts' file:

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

// Required components for route services activation
import { LandingComponent } from '../../components/landing/landing.component';
import { DashboardComponent } from '../../components/dashboard/dashboard.component';
import { UserprofileComponent } from '../../components/userprofile/userprofile.component';
import { WrongRouteComponent } from '../../components/wrong-route/wrong-route.component';

const routes: Routes = [
  { path: '', component: LandingComponent},
  { path: '/dashboard', component: DashboardComponent},
  { path: '/userprofile', component: UserprofileComponent},

  // Handling wrong routes by displaying the custom 404 page
  { path: '404', component: WrongRouteComponent},

];

I need assistance in making changes or additions to the following line of code within the routing configuration:

{ path: '404', component: WrongRouteComponent},

Answer №1

You can easily accomplish this task

{
    path        : '**',
    pathMatch   : 'full',
    component   : WrongRouteComponent
}

Remember to add this wildcard route at the end of your routing file within the routes array.

I trust this information will be beneficial to you.

Answer №2

A wildcard route is designed to catch any paths that are not explicitly defined in your constants file. When the URL does not match any specified routes, it can cause the router to throw an error and crash the application.

Routes are typically evaluated from top to bottom, so it is crucial to place the wildcard route ('**') at the end of the route list. Placing it at the beginning could result in all other routes being treated as undefined.

You can implement a wildcard route like this:

{ path: 'not-found', component: NotFoundComponent }
{ path: '**', redirectTo: '/not-found' }

Alternatively, you can use:

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

Answer №3

Kindly update the path from '404' to **

Therefore, the correct routes should be 

const routes: Routes = [
  { path: '', component: LandingComponent},
  { path: '/dashboard', component: DashboardComponent},
  { path: '/userprofile', component: UserprofileComponent},

  //Incorrect route
  { path: '**', component: WrongRouteComponent},

];

Answer №4

Here is the solution that resolved my issue.

const appRoutes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'about', component: AboutComponent },
  { path: 'contact', component: ContactComponent },

  // Catch All Route
  { path: '**', redirectTo: '/notfound' }
];
