What to notice

  1. Refresh the page - the timestamp and random number do not change
  2. The HTML was generated at build time and is now cached on the CDN
  3. Fastest possible page - zero server compute per visit
  4. Heads up: in dev mode the values do change. SSG locking only kicks in after a build

When to use in WordPress

  • Blog posts & pages - content rarely changes between deploys
  • Marketing pages - hero, about, services, landing pages
  • Product catalogs with infrequent updates
  • Pair with a WordPress webhook on post save to trigger a rebuild (Vercel/Netlify deploy hook)
  • Use getStaticPaths() to pre-build every WP post at deploy time
