What problem does it solve?
Next.js apps often struggle to balance fast page loads with the need for fresh, request-specific data; this skill helps you use Cache Components to mix static, cached, and dynamic rendering within the same route.
Core Features & Use Cases
- Enables Cache Components (Next.js 16+): Turns on
cacheComponents in next.config.ts so routes can leverage Partial Prerendering.
- Separates Static, Cached, and Dynamic content: Uses synchronous logic for static output, the
use cache directive for cached data, and Suspense streaming for truly dynamic UI.
- Controls cache lifetime and invalidation: Uses
cacheLife() for staleness/revalidation/expiration and cacheTag() plus updateTag()/revalidateTag() for targeted cache invalidation.
- Handles runtime-data constraints safely: Prevents invalid usage of
cookies(), headers(), and searchParams inside use cache, offering the correct refactor pattern or the use cache: private escape hatch.
Quick Start
Enable Cache Components by setting cacheComponents: true in your next.config.ts, then wrap your async cached data function with use cache and optionally add cacheLife() and cacheTag() for predictable staleness and invalidation.
