# Introduction to Next.js

The next generation react framework

Next js is an application built on top of react for server side rendering.To build a complete web application with React from scratch, there are many important details you need to consider:

* Code has to be bundled using a bundler like webpack and transformed using a compiler like Babel.
* You need to do production optimizations such as code splitting.
* You might want to statically pre-render some pages for performance and SEO. You might also want to use server-side rendering or client-side rendering.
* You might have to write some server-side code to connect your React app to your data store.

A *framework* can solve these problems. But such a framework must have the right level of abstraction — otherwise it won’t be very useful. It also needs to have great "Developer Experience", ensuring you and your team have an amazing experience while writing code.

#### Next.js: The React Framework

Enter **Next.js**, the React Framework. Next.js provides a solution to all of the above problems. But more importantly, it puts you and your team in the pit of success when building React applications.

Next.js has the best-in-class "Developer Experience" and many built-in features; a sample of them are:

* An intuitive page-based routing system (with support for dynamic routes)
* Pre-rendering, both static generation (SSG) and server-side rendering (SSR) are supported on a per-page basis
* Automatic code splitting for faster page loads
* Client-side routing with optimized prefetching
* Built-in CSS and Sass support, and support for any CSS-in-JS library
* Development environment which supports Hot Module Replacement
* API routes to build API endpoints with Serverless Functions
* Fully extendable

Next.js is used in tens of thousands of production-facing websites and web applications, including many of the world's largest brands.
