Next.js middleware enables developers to run custom code before completing a request, directly influencing the response to improve performance and security. Introduced in v12 and further enhanced in later versions, middleware allows responsive interactions with requests, making applications more dynamic. In v15, support for Node.js runtime has been added, extending its versatility. It plays a crucial role in conjunction with Vercel Edge Functions, streamlining the functionality of web applications by simplifying request/response management and allowing tailored actions such as URL redirects and header enrichment.
Next.js middleware allows developers to execute code before a request is completed, modifying responses to enhance performance and security at the network's edge.
Introduced in Next.js v12 and improved in subsequent versions, middleware now directly responds to requests without needing a route handler, optimizing web application efficiency.
