NextJS Tips Series: Custom 500 error page

The 500 errors are handled both client-side and server-side by the Error component.

If you wish to override it, define the file pages/_error.js and add the following code.

// pages/_error.js
function Error({ statusCode }) {
  return (
    <p>
      {statusCode
        ? `An error ${statusCode} occurred on server`
        : 'An error occurred on client'}
    </p>
  )
}

Error.getInitialProps = ({ res, err }) => {
  const statusCode = res ? res.statusCode : err ? err.statusCode : 404
  return { statusCode }
}

export default Error;

Thank you :)
