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.
