Next.js 16: Your v15 Fetch Pattern Is Broken 🚨

Description

Next.js 16 made async Server Components the baseline for data fetching — not optional sugar. If you're still using useState + useEffect to fetch on the client, you're shipping unnecessary JS, triggering hydration mismatches, and leaving Time to Interactive on the table. This video shows the exact before/after: the v15 pattern vs the v16 Server Component + React cache() approach, with revalidation built in. Three moves, instant first paint, zero client overhead. #nextjs #nextjstutorial #webperformance #typescript
