React Server Components Migration: Moving Existing Components From Client to Server Without Breaking Your App
Adopting the App Router is only half the work. The other half is migrating the client components you already have to server components without regressions. Here is the process we use: boundary mapping, leaf extraction, context handling, and a verification strategy that catches breakage before users do.
Clerk vs Auth.js v5 in 2026: The Decision That Defines Your Auth Roadmap
