5 Things AI Can't Do, Even in • Next.js

This report examines limitations AI-assisted tools encounter in Next.js development process. Five main topics address technical nuances specific to Next.js infrastructure: component and page semantics including differences between SSR, SSG, and ISR, data fetching and caching covering getServerSideProps, getStaticProps, App Router fetch, and cache headers, routing and dynamic routes with i18n and Middleware edge cases, performance and build toolchain addressing image optimization, ISR, server components, and packaging, and finally security and deployment examining Edge versus Server environments, secret keys, and header management. Each section provides technical detail, concrete error scenarios AI encounters explained through real-world examples from GitHub issues and blog posts. For instance in data fetching, getStaticProps usage is emphasized because this function runs only on server and doesn't get included in client bundle, meaning secret keys or private request information don't l
