Next JS vs React JS: Why Should You Switch from React to Next JS?

Front-end development often involves the use of JavaScript technologies such as React JS and Next JS. Whilst both of these technologies are designed to create user interfaces (UI), one is superior to the other. This essay outlines the primary differences between React JS and Next JS, and examines why you should consider transitioning to Next JS.

Let’s get started.

React JS

In 2012, Facebook released React JS, an open-source front-end JavaScript library, to the public. This library is widely used in the development of web pages and mobile applications, providing developers with a robust and powerful tool for creating user interfaces. React JS has become a popular choice for developers, as it offers an efficient and scalable way to build dynamic user interfaces.

React.js is primarily focused on managing state and rendering it to the Document Object Model (DOM). As a consequence, developers often need to use additional frameworks to incorporate routing and other client-side features when creating React applications.

Next JS

Next.js offers a range of capabilities that can help developers optimise the size of their builds, speed up the compilation process, preview their work, export their project as a static asset, and even pre-render the application. These features provide developers with greater control over the development process and help enable faster, more efficient coding.

Next JS vs. React JS: A Quick Comparison

React is an effective technology when utilised in conjunction with stream templating libraries, and it is a viable choice for constructing dynamic web applications. Nevertheless, due to the ever-evolving nature of technology, crafting comprehensive documentation for React JS is a challenging task. Additionally, there are a number of reasons why Next JS surpasses React JS.

Next JS versus React JS: Usability

It is quite simple to create web pages for a React JS project. To acquire access, you build a component and then attach it to the router.

Despite the fact that creating web pages with Next JS is much more straightforward, the process involves two steps: placing the page under the page folder and linking the necessary header component. Moreover, the number of lines of code required by Next JS is reduced, making the project more accessible and understandable for developers.

Next JS vs. React JS: Performance

Next.js offers features such as image optimisation, internationalisation, and incremental static generation, allowing developers to quickly and efficiently construct applications. Therefore, thanks to these features, Next.js applications are seen to be more performant than those built with React.js.

Furthermore, although React JS enables client-side rendering, it is inadequate when dealing with many clients.

Following JS vs. React JS: Features

  • Server-Side Rendering (SSR)

    Server Side Rendering (SSR) pre-populates a page with custom content in Next JS, making it easy for users to navigate a web page. By processing and returning data retrieval requests in HTML format, this method saves time and makes the product more accessible to a wider audience.
  • Static export (SSG)

    JS then mixes SSR with SSG. It enables developers to construct websites that render as they work on them. React JS does not support pre-rendering.
  • Search engine optimisation

    Next, owing to the SSR and SSG features, JS may improve SEO rankings.
  • Bundling and code splitting

    Subsequently, the JavaScript code is remarkably lightweight and can be broken down into smaller components. As a result, instead of being sent in large quantities, the code is uploaded in small, highly efficient packages.

Next JS vs. React JS: Verification

Having comprehensive documentation is essential for gaining an understanding of all the components of a software package, its tools, and libraries. Fortunately, both React JS and Next JS provide thorough documentation for their respective users.

Next JS vs. React JS: Community for Development

The Next JS and React JS development communities are both highly populated and filled with resources to help developers in their coding journey. The collaborative atmosphere within these communities provides developers with a variety of ideas and solutions to their problems, allowing them to expand their knowledge and clear up any confusion or uncertainty they may have.

Next JS vs. React JS: Cost of Development

Next.js and React.js are both open-source web development platforms, which means they have the potential to reduce development costs compared to other platforms. Additionally, transitioning from React.js to Next.js is not a costly endeavour, making it an attractive option for developers who are looking to upgrade their technology stack.

What are the Next JS applications?

Next.js is quickly gaining traction in the web development world due to its robust capabilities. This platform enables developers to create secure, fast applications that include server-side rendering, which improves the user experience. In addition to its many advantages, Next.js offers a wide range of uses, such as:

  • Make landing pages

    Due to its ability to provide rapid and secure website construction, Next JS is increasingly being employed to create landing pages and other sites designed for promotional purposes.
  • Make an online eCommerce shop

    Next JS includes an e-commerce starting kit that allows developers to build high-performing, SEO-friendly, and user-friendly online stores.
  • Make quick webpages

    NextJS has the advantage of shorter loading times due to its ability to render the application on the server. This is beneficial for all visitors, as it ensures that websites load quickly, which is especially important for those using slower devices. By using NextJS, website owners are able to provide a better user experience for all visitors, no matter their device’s capabilities.


In this essay, we have sought to thoroughly compare and contrast Next JS and React JS. Both of these frameworks provide an extensive array of features and support for developers, however, the one that is most suitable for you will be contingent upon your particular requirements.

ReactJS offers developers more flexibility in the development process, while NextJS provides a greater range of features. React allows developers to create anything they desire, but NextJS comes with built-in tools and standards that make it much easier to use.
