Cache Components in Next.js 16 provide explicit caching via the "use cache" directive or use cache hook, enabling Partial Prerendering (PPR) to statically prerender cacheable sections for instant navigation while streaming dynamic parts through Suspense boundaries. They unify server/client caching with automatic keying and integrate revalidation tags for control.

Example:

Code

// app/dashboard/page.tsx (with next.config.ts: { cacheComponents: true })
"use cache";

async function UserStats({ userId }: { userId: string }) {
  const stats = await fetch(`https://api.example.com/stats/${userId}`, {
    next: { tags: ['user-stats'] }
  }).then(res => res.json());
  return 
Views: {stats.views} | Sales: {stats.sales}
;
}

export default async function Dashboard({ params }: { params: Promise<{ userId: string }> }) {
  const { userId } = await params;
  return (
    <>
      <h1>Dashboard</h1>
      <Suspense fallback={<div>Loading stats...</div>}>
        <UserStats userId={userId} />
      </Suspense>
    </>
  );
}
