Change the Nuxt.js server error page

I bet every Nuxt.js developer has seen this error page at least once:

Default Nuxt Server Error Page

And I’m sure that you’ve asked yourself: How to change this page? You likely want to brand this error page similar to your client side error pages, so that your users aren’t as confused whenever a server-side error occurs and have info available how to proceed further.

Testing the server-side error page

Let’s create a new dummy page called error.vue in the pages folder:

export default {
  asyncData() {
    throw new Error(':(')
  }
}

To see the page you have to boot up the project in production mode. Otherwise youch will kick in and give you information about the occurred error. After going through npm run build && npm start, open the page (f.ex. with localhost:3000/error) and you should see the error page.

Okay… changing time!

Changing text

Do you like the style and just want to change the text there? No problem! You can do this through your nuxt.config.js. The text for the default error pages is extracted from the message object. The important default values can be found below:





 
 
 
 
 
 





export default {
  messages: {
      loading: 'Loading...',
      error_404: 'This page could not be found',
      server_error: 'Server error',
      nuxtjs: 'Nuxt.js',
      back_to_home: 'Back to the home page',
      server_error_details:
        'An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.',
      client_error: 'Error',
      client_error_details:
        'An error occurred while rendering the page. Check developer tools console for details.'
  }
}

I’ve highlighted the lines that influence the text of the default server error page. Let’s change them and see what happens!

export default {
  messages: {
      server_error: 'Oh no! Server error',
      nuxtjs: 'Is this Nuxt.js?',
      back_to_home: 'Cmon, back home!',
      server_error_details: 'Uh uh :| Server errorrrrr',
  }
}
Altered Nuxt Server Error Page showing the heading 'Oh No! Server error' and the message 'Uh uh :| Server errorrrrr'

Looks great so far! But as you may think, this isn’t everything 😏

Completely replace the error page

Surprise folks! Similar to an own app.html file, you can also replace the server-side error page.

All you have to do is to create a folder called app in your project root and another one inside it called views. Now add an error.html file inside the views folder and edit it to customize your error page.

HTML means: no Vue/Nuxt logic, only pure HTML and CSS. Of course, you can add javascript (eg. error reporting tools) and so on if you want.

I’ll add a small unstyled piece of HTML for demo purposes.

/app/views/error.html:

<h1>Oh No :(</h1>
White screen showing the characters 'Oh no :('

There we go!

Conclusion

It was easier than you thought, wasn’t it? Now it’s your turn! 🙊 I’d love to see some nice error page designs, so if you built a great one and want to share it be sure to send it to me as well.
