To cache components in Next.js 16+, enable cacheComponents: true in next.config.ts and apply the 'use cache' directive to selectively cache routes, components, and server actions, reducing server workload and improving page performance.

The 'use cache' directive in Next.js is used for fine-grained caching control, allowing developers to differentiate static rendering, cached data, and dynamic content within pages and components using cacheLife and cacheTag semantics.

Yes, component-level caching works with dynamic content by using Suspense boundaries to isolate dynamic sections, while applying 'use cache' directives to static and cached data sections to optimize overall rendering performance.

You control cache revalidation and lifecycles in Next.js server components by using cacheLife to define duration, cacheTag for grouping, and updateTag or revalidate semantics to enforce correct cache invalidation and refresh behaviors.

A key limitation of using 'use cache' in Next.js is preventing unsafe runtime data access inside cached sections, requiring strict separation of static cached data from dynamic content to avoid rendering inconsistencies and stale data issues.

Yes, you can use cacheLife and cacheTag for selective caching in Next.js dashboards and data-heavy UIs, allowing fine-grained control over cached data while maintaining dynamic content rendering via Suspense boundaries.
