What is NextJS? (Uses, Features, and Examples in 2023)

NextJS is a robust React-based JavaScript framework that enables developers to build server-side rendered and statically generated web applications. It provides an intuitive developer experience with features like automatic code splitting, integrated routing, and hot reloading.

This blog article will explore the advantages of using NextJS for developing projects. Also, it will discuss why it has become one of the most popular frameworks for modern web development.

What is NextJS?

NextJS is a React-based JavaScript framework for building server-rendered, SEO-friendly websites and web applications. It provides developers with a complete toolset for creating rich user experiences with minimal setup and configuration.

NextJS enables developers to build high-performance websites that load quickly and respond instantly to user interactions. Additionally, it comes with features such as automatic code splitting, client-side routing, and built-in CSS support.

A Brief History of NextJS

Next.js is a React-based open-source framework created and maintained by Vercel (formerly Zeit). It was initially released in October 2016 and has gained immense popularity. NextJS enables developers to develop server-rendered React applications with minimal setup and zero configuration.

Next was created to address the need for a framework that would make it easy for developers to create applications with modern JavaScript features, such as ES6, JSX, and CSS Modules. It also provides an optimized experience for users on the server side.

The framework allows developers to quickly build their applications without worrying about setting up complicated configurations or dealing with complex build tools.

Since its initial release in 2016, NextJS has become one of the most popular frameworks for developing React applications due to its ease of use and robust feature set.

With its comprehensive documentation and active community of contributors, Next continues to be an integral part of modern web development today.

Features of NextJS

Below we will detail some of the features of NextJS and the benefits of using it in product development projects.

1. Server-side Rendering (SSR)

Next provides server-side rendering out of the box, making it easy to build high-performance websites and applications with minimal effort. This allows your application to render HTML on the server before sending it to the browser, resulting in faster page loads and a better user experience.

2. Automatic Code Splitting

NextJS automatically splits your code into smaller chunks for faster loading times and improved performance. This helps reduce the amount of data sent over the network and significantly speeds up page load times.

3. Hot Module Replacement

Next supports hot module replacement. This allows developers to quickly reload changed modules without restarting the entire application or reloading the page in the browser. For this reason, development is much faster and more efficient since changes can be seen immediately in the browser without downtime or interruptions for users.

4. Static Site Generation

Static site generation allows developers to generate static HTML pages from dynamic React components at build time instead of serving them dynamically each time a request is made. NextJS supports this feature. This reduces server load and improves performance significantly, as additional processing is unnecessary for each request.

5. Customizable Webpack Configurations

Next includes customizable Webpack configurations that allow developers to customize their build process according to their needs and preferences. Experienced developers and beginners can easily use and understand these configurations, making them ideal for web development projects using React and NextJS.

Which companies are using NextJS?

Next is especially useful for creating server-side rendered (SSR) React applications, and it also provides features such as automatic code splitting, static optimization, and client-side routing.

Some of the most well-known companies using NextJS include Airbnb, Dropbox, Uber, Twitch, Twitter, and GitHub.

Airbnb uses Next for its website, and the company has found that it helps them quickly build new features with fewer bugs.
