Middleware in Next js

Understanding Middleware in Next.js

Middleware plays a crucial role in web development, enabling developers to perform various tasks such as authentication, logging, and request processing. In Next.js, middleware provides a powerful mechanism to intercept and handle HTTP requests before they reach the actual route handlers.

What is Middleware?

Middleware refers to a software layer that sits between the client and the server, intercepting and processing requests and responses. In the context of web development, middleware functions execute specific tasks related to request processing, such as parsing incoming data, adding headers, or performing authentication checks.

Middleware in Next.js

Next.js, a popular React framework for building server-rendered applications, introduces middleware through its API routes feature. API routes allow developers to create server-side logic using JavaScript or TypeScript, and middleware can be applied to these routes to modify or augment request and response objects.
