Render XML Page with Next.js

Learn how to generate an XML page with Next.js.

To render a page in Next.js as XML (or really any other non-HTML format), here’s a pattern that I’ve found works well:

const Sitemap = () => null;

export const getServerSideProps = async ({ res }) => {
// Fetch data and build page content ...
const content = "...";

res.setHeader("Content-Type", "text/xml");
res.write(content);
res.end();

return {
props: {},
};
};

export default Sitemap;

This pattern may look a little odd, so let’s break it down:

  • Nothing is rendered from the component. The page component is just an empty component that renders null.
  • getServerSideProps hijacks the Node.js response by 1) setting the appropriate content type header, and 2) returning with the content (as a string) to be rendered on the page.

Note that we still want to return the props object or Next gets mad.
