Automatic Static Optimization is a feature provided by Next.js that automatically generates static HTML for pages at build time, without the need for any configuration. This process hinges on whether the page includes blocking data requirements or not. If a page doesn't need to fetch external data for initial rendering or relies on external data fetched at build time (using getStaticProps), Next.js will automatically optimize that page to be served as a static HTML file. The optimization process effectively eliminates the need to render the page server-side or fetch external data client-side on each request.
The benefits of Automatic Static Optimization are numerous and significant. Firstly, it dramatically improves the performance of web applications. Static...
