Error pages are an essential part of any web application, providing users with a clear and informative message when something goes wrong. Nuxt 3 makes it easy to create custom error pages that are tailored to your application’s needs. In this article, we’ll walk you through the process of creating a custom error page in Nuxt 3.
Prerequisites
Before you begin, make sure you have the following installed:
- Node.js
- npm or yarn
- Nuxt CLI
Creating the Error Page
To create a custom error page, you’ll need to create an error.vue file in the root directory of your Nuxt application. This file will be responsible for rendering the error page whenever an error occurs.
The basic structure of the error.vue file is as follows:
<template>
<div class="error-page">
<h1>Oops, something went wrong!</h1>
<p>{{ error.message }}</p>
</div>
</template>
<script>
export default {
props: {
error: Object
}
}
</script>
<style scoped>
.error-page {
text-align: center;
margin: 50px auto;
}
</style>This code will render a simple error page with a title and a message. You can customize the HTML, CSS, and JavaScript to create the error page you want.
Handling Specific Error Codes
You can handle specific error codes by checking the statusCode property of the error object. For example, to handle a 404 error, you could add the following code to your error.vue file:
<template>
<div class="error-page">
<h1>{{ statusCode === 404 ? 'Page not found' : 'Oops, something went wrong!' }}</h1>
<p>{{ error.message }}</p>
</div>
</template>This code will display a different message depending on whether the error code is 404 or not.
Global Error Handling
If you want to handle errors globally, you can use the useError composable. This composable provides access to the current error object, and you can use it to display a custom error message or redirect to a different page.
For example, to display a custom error message whenever an error occurs, you could add the following code to your app.vue file:
<script setup>
import { useError } from '#app'
const error = useError()
if (error.statusCode) {
return <error.vue />
}
</script>This code will check for an error and, if one exists, it will render the error.vue component.
Creating custom error pages in Nuxt 3 is a straightforward process that allows you to provide a more personalized and informative experience for your users when something goes wrong. By following the steps outlined in this article, you can easily create custom error pages that are tailored to your application’s needs.
