title: Is it possible to not rebuild the whole app but generate new static files only in Nextjs?
body: <p>I've just started using <strong>NextJs</strong> <code>getStaticProps</code>, and static files generated at <code>build time</code> is <strong>neat</strong>. But my contents just don't stay unchanged, I need static files to be updated but rebuilding the app everytime there's a modification is costly. Is there a way to generate new static files only. <code>getServerSideProps</code> turned out to be taking a big amount of time til first byte.</p>
