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
revalidateandcache: 'force-cache'intentionally - For dashboards, opt into
no-storeonly 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
metadatain App Router; render OpenGraph images per post
Cut friction, ship faster.
