Version 3 Update

In version 3 of Nextra useData was moved to nextra/hooks:

import { useData } from 'nextra/hooks'

getStaticProps

With Next.js, you can pre-render your page using Static Generation (SSG) (opens in a new tab). Your pages will be generated at build time and statically served to visitors. It can also be cached by a CDN to maximize the performance.

This is supported by Nextra too. See section Next.js SSG (opens in a new tab).

If you export a function called getStaticProps (Static Site Generation) from a page, Next.js will pre-render this page at build time using the props returned by getStaticProps.
