Next.js is a Java framework that makes sure that the developers can build user-friendly websites. It is built with JavaScript, Babel, and webpack. It is usually used to build a static webpage or application.

There are many benefits to using Next.js and it is being updated regularly by the Vercel team.

The new release that has been announced at Next.js Conference is considered to be "the biggest release ever".

What's new

With the new release, many drastic changes have been made for the developers. Here are the highlights:


Middleware is software that enables communication between the operating system and the applications that run on it.

The team introduced Middleware to give the developers a full sense of flexibility since it allows them to prioritize and use code over configuration. Now the developer can edit the response by rewriting or redirecting before the request is completed.

The plan for React 18 has been explained by the React team and they have been working on it for a few months now. It hasn't been launched yet but since the plan has been announced, the Next.js team calls their new features that work with React 18 to be experimental.

The new Suspense feature of React 18 made the Next.js team come up with ideas such as using server-side streaming and React Server Components. The users will have to enable these new features, they will have to use experimental flags with a line of code.

The improvements don't end here yet. Some of the other features include:
