In this post we are going to create a custom error page or a custom 404 page in a Next JS website.
What is a custom error / 404 page?
The 404 page is shown when the requested resource or the requested URL cannot be found on the server and as a response, it returns a 404 page. By default Next Js provides a static 404 page as shown below:
Default 404 / error page
Creating a custom error / 404 page
To create a custom 404 page, you first need to create a “404.js” named file in your pages directory. This file is statically generated at build time.
creating a 404,js file
In this page create and export a custom component and the rest will be taken care of by Next Js.
Javascript
// Inside the "pages/404.js" file add the below codeexport default function Custom404() { return <> YOUR COMPONENT HERE </>} |
Example: Creating a custom error page in Next.js. Write down the following code in 404.js file.
Javascript
// Inside the "pages/404.js" fileexport default function Custom404() { return ( <div> <h1> Welcome to <span style={{ color: "green" }}> GeeksForGeeks </span> </h1> <p>Sorry , The page you are looking for can't be found</p> <p>Try checking your URL</p> <h2> This is a <span style={{ color: "red" }}>404 page</span> </h2> </div> );} |
Step to Run the application: Now to start the development server you have to type the below command in the terminal.
npm run dev
Output: And now let us go to a non-existing page on the website to encounter the 404 error.

Note: You can use getStaticProps inside this page if you need to fetch data at build time.
