Next.js 16 Full Course #9: Not Found Page

Description

In Video #9 of our Next.js 16 Full Course, we learn how to gracefully handle 404 errors. 🚀 A professional website never shows a generic browser error; it shows a branded, helpful "Not Found" page that keeps users on the site. We will explore the special not-found.tsx file convention in the App Router and learn how it can be used at the root level or nested within specific route segments. I’ll also show you the notFound() function from next/navigation, which is a lifesaver when dealing with dynamic data fetching in 2026.
