In this video, we’ll break down a common Next.js App Router mistake that can block your entire page from rendering 🚫
If you’re fetching data at the page or layout root level, Next.js will wait for the request to finish before rendering anything — causing slow loads and poor user experience.
❌ The Problem
Data fetching at the page root
Entire route gets blocked
No partial rendering
Users see nothing until the request completes
✅ The Solution
Move data fetching logic into the component that actually needs it
Wrap only that component with a Suspense boundary
Let the rest of the page render instantly
Show a loading state only where needed
