Avoid common mistakes with the Next.js App Router
Blog post from Upsun
The Next.js App Router offers new features like React Server Components, improved caching, streaming responses, and nested layouts, enhancing both user and developer experiences. However, incorrect utilization of these features can result in bugs or performance issues. Common mistakes include making redundant network requests on the client side, incorrectly rendering dynamic routes as static, improperly mixing server and client components, and misplacing Suspense boundaries. Additionally, server-specific actions should not be used directly in client components, and React Context should not be used in server components. The App Router also requires careful handling of dynamic routing, API configurations, and module imports to avoid functionality issues and security risks. Properly addressing these pitfalls can significantly improve application performance and user experience.
