Incremental Static Regeneration (ISR)

A Next.js pattern that combines SSG performance with dynamic content updates without full rebuilds.

Incremental Static Regeneration (ISR) is a Next.js rendering pattern that combines static site generation's performance with dynamic content updates. Pages are statically generated at build time, then re-generated on-demand or on a schedule (revalidate option) without rebuilding the entire site. ISR is ideal for sites with content that changes occasionally — e-commerce product pages, blog posts, documentation. ISR delivers near-SSG performance with content freshness comparable to SSR, at significantly lower hosting cost. Empire325 uses ISR strategically for content-heavy applications where instant freshness isn't required.
