Caching & Revalidating

Incremental Static Regeneration with stale-while-revalidate semantics.

Export revalidate from a page to control how long its rendered HTML is cached by the Rust layer.

// cache for 60s, then revalidate in the background
export const revalidate = 60;

// cache indefinitely
export const revalidate = false;

// never cache (default)
// (omit the export)

How it works

Cached pages are served from memory in microseconds. When a page is stale, GioJS serves the stale copy immediately and revalidates in the background — visitors never wait.
