Next.js provides several ways to create redirects in applications, including defining them in the next.config.js configuration file, using middleware, and utilizing the useRouter hook on the client-side. Permanent redirects have an HTTP status code of 301 or 308, indicating a page has moved permanently, while temporary redirects have an HTTP status code of 302 or 307, indicating a page has moved but will return to the current URL in the future. Redirects can be used for both site-wide and user-specific conditions, with middleware suitable for complex redirects that involve multiple checks, such as authentication and authorization. The useRouter hook is ideal for client-side redirects triggered by user actions. Properly managing Next.js redirects is crucial to maintaining a seamless user experience, ensuring SEO, and preventing dead links.
