How to override the default 404 screen in Qwik?

Overriding the default 404 screen in Qwik is a relatively straightforward process. Qwik is a frontend framework optimized for server-side and client-side rendering, which allows developers to customize error handling with minimal configuration, including 404 error pages. Below are the steps and a simple example:

Steps

1. Create a Custom 404 Page: First, you need to create a new Qwik component that will serve as your custom 404 page. You can use the tools and libraries provided by Qwik to design and implement this page.

2. Configure Routing: In Qwik, routing is managed by the @builder.io/qwik-city plugin. You need to specify in your routing configuration file which component should be rendered when a route is not found.

3. Update the routes.ts File: In Qwik's project structure, there is typically a routes.ts file used to define all routes. In this file, you can add a rule to capture all unmatched routes and point it to your custom 404 component.

Example

Suppose you have already created a Qwik component named NotFoundPage. You can set up your routes.ts as follows:

typescript
import { component$ } from '@builder.io/qwik';
import { QwikCity } from '@builder.io/qwik-city';
import NotFoundPage from './path/to/NotFoundPage';

export default QwikCity({
  routes: [
    {
      path: '/',
      component: () => import('./path/to/HomePage'),
    },
    {
      path: '**',
      component: NotFoundPage,
    },
  ],
});

In this example, when a user accesses a non-existent route, the Qwik framework automatically renders the NotFoundPage component. This allows you to provide a more user-friendly interface to inform users that the page they are trying to access does not exist, rather than displaying the default 404 page.

Conclusion

By doing this, you can easily override the default 404 page in your Qwik application, providing a user experience that aligns with your website's style. This not only enhances user experience but also plays a crucial role in maintaining brand consistency.
