Show Notes 03:34 - Server-rendered Both do server rendered Gatsby is gone at build time Next is done at build and on deploy 05:26 - Static generation getStaticProps() getServerSideProps() 08:25 - Re-rendering pages Gatsby can be re-rendered and re-deployed - any CMS lets you do this on only the pages that changed.
