Exploring Various Coding Languages
Next.js extends the native Web Request and Response APIs with NextRequest and NextResponse, offering powerful tools for managing cookies, headers, redirects, rewrites, and JSON responses. These utilities simplify server-side logic and improve control over routing, personalization, and security. This guide walks through their capabilities with practical examples and best practices.
The redirect function in Next.js allows you to navigate users to a new route, returning either a 307 or 303 HTTP response depending on context. It works in Server Components, Client Components, Route Handlers, and Server Actions. The refresh function is used exclusively within Server Actions to refresh the client router. This article explains how both functions work, with practical examples and key considerations.
Next.js introduces powerful experimental features for access control and smart caching. This guide covers the unauthorized() function for custom 401 handling, unstable_cache for persistent memoization, updateTag for instant cache invalidation, and useLinkStatus for inline navigation feedback. Learn how to use these tools to build secure, performant, and responsive applications.
Next.js provides a rich set of client-side hooks and caching utilities that empower developers to build dynamic, responsive, and secure applications. From reading route parameters to tracking navigation state and reporting performance metrics, this guide walks you through the most important tools available in the App Router.
