Next.js App Router — Worth the Migration?
Migrated from Pages Router to App Router. Server components are a game-changer but the learning curve is real.
Migrated from Pages Router to App Router. Here's my experience.
What Changed
- Server Components by default — less JavaScript shipped to client
- Nested layouts — finally, persistent UI across routes
- Streaming and Suspense — progressive loading built-in
- Route handlers replace API routes
The Good
Server components are a paradigm shift. Fetching data directly in components without useEffect or getServerSideProps feels natural. Less client-side JavaScript means faster pages.
The Challenges
- Mental model shift — thinking in server vs client components
- Caching behavior can be surprising
- Some libraries aren't App Router compatible yet
My Verdict
Worth it for new projects, absolutely. For existing apps, migrate incrementally.
