Study the solution

You export consts from a layout/page/route to control behavior: dynamic ('auto'|'force-dynamic'|'force-static'), revalidate (ISR interval), runtime ('nodejs'|'edge'), fetchCache, and dynamicParams. They override the defaults for that segment.

Read the code

Segment config exports
// app/feed/page.tsx
export const dynamic = 'force-static';   // always prerender
export const revalidate = 3600;          // ISR: refresh hourly
export const runtime = 'edge';           // run on the Edge runtime

export default async function Feed() { /* ... */ }
