Automatic static generation

In Next.js, the filesystem-based routing means that each path in your web application corresponds to a file in the pages directory of your application. For example, / corresponds to pages/index.js.

Next.js defaults to static generation when no Next.js data fetching methods are used for a given page. You can find more information from the Next.js documentation – Automatic Static Optimization (https://nextjs.org/docs/pages/building-your-application/rendering/automatic-static-optimization).

Next.js automatically determines that a page is static (i.e., can be prerendered) if it has no blocking data requirements. This determination is made by the absence of getServerSideProps and getInitialProps on the page.

For example, the following page in a Next.js application will be statically generated, since it only exports a page component (the default export of Index); no getServerSideProps or getInitialProps function is exported:
