Partial Prerendering (PPR)

PPR allows you to combine static and dynamic content in a single route:

export default function Page() {
  return (
    <>
      <StaticComponent /> {/* Served from cache */}
      <Suspense fallback={<Skeleton />}>
        <DynamicComponent /> {/* Streamed on demand */}
      </Suspense>
    </>
  );
}
