Deploys are now up to 33% faster for apps with many ISR pages

Read on vercel.com

Summary

Vercel now ships ISR page metadata together with the page files, removing a separate upload step. This reduces deploy times by up to a third for apps that have many ISR or partially prerendered pages, with no extra configuration needed.

  • ISR page routing metadata is now bundled with the page assets instead of being uploaded separately.
  • Bundling eliminates an extra upload step, cutting deploy time by up to 33% for apps with many ISR pages.
  • The change also applies to Partial Prerendering pages, offering the same speed benefit.
  • No configuration is required; the optimization is applied automatically to every Vercel deploy.

Frontend engineers using Next.js on Vercel should care because faster deploys speed up iteration and reduce CI costs for sites that rely heavily on ISR.
