Next.js App Router Best Practices (2025 Edition)

A concise collection of patterns I use in production projects.

RSC Boundaries

  • Keep components server by default
  • Make client components small and event-driven

Caching

  • Use revalidate and cache: 'force-cache' intentionally
  • For dashboards, opt into no-store only where needed

Server Actions

  • Validate input with Zod
  • Return typed payloads, not strings
  • Centralize error shapes

Images

  • Prefer fill + sizes; preconnect critical domains

SEO

  • Use metadata in App Router; render OpenGraph images per post

Cut friction, ship faster.
