Original: Fixing Client-Server Waterfalls After Migrating from Vite to Next.js
Short summary
Migrating from Vite to Next.js often introduces client-server waterfalls when developers copy useEffect-based fetching patterns into SSR. The fix is to fetch data in Server Components using async/await, parallelize requests with Promise.all, and stream slow components with Suspense boundaries. Using next/image and next/font further reduces load bottlenecks by prioritizing critical assets during HTML parsing.
- •Fetch data in Server Components instead of useEffect to avoid client-server waterfalls
- •Parallelize multiple data requests with Promise.all instead of sequential awaits
- •Use Suspense boundaries to stream slow components and improve perceived performance
