What is the Difference Between React and NextJs


The developer experience is usually taken into consideration when selecting a software library or framework. The developer experience is how effectively the developer can do the job. Developers often choose libraries or frameworks that are interesting and simple to use. This is a big reason why we now have the most popular libraries and frameworks.

So, in this post, you’ll find your answers to the following questions:

  • What are the differences between React and Nextjs?
  • What are the differences between SSR and CSR?
  • What are the issues in using React?
  • The Performance difference between React and NextJs?

React vs. Nextjs

React is a JavaScript library that helps you to build user interfaces using components as building blocks. React is an open-source JavaScript front-end library for creating user interfaces or UI components. It is managed by Facebook and a community of independent developers and organizations. React may be used as a foundation for single-page or mobile apps.

Next.js, on the other hand, is a React-based framework for developing Node.js server-side applications. This means you’ll design pages with the same component-oriented logic and utilize the Next.js routing engine for page-to-page navigation. Because server-side rendering allows loading time to be spread out over time, actual speed will almost certainly improve.

Some React Background

React is wonderful for interactivity and high-performance components, but when people started adopting these technologies to construct everything on React, it caused issues for clients side.

A basic Contact page, which might have been a plain HTML/CSS page, was now a page with a large JS bundles. To show the contents, the browser has to first download to the client browser, then parse, then execute, and finally update the DOM.

Everyone felt the impact of this. Clients experienced longer load times. Browsers have to work hard to execute JS. And it was not SEO friendly.

People like coding in React and other related technologies but they were also aware of the risks of executing too much JS client browser.

The Solution

When developers noticed that delivering too much React code to the client was an issue, they wanted to know: Is it feasible to code in React while sending HTML pages to clients?

And besides, when the React code has finished executing JavaScript, all you get is an HTML page.

As a result, they started working on Server Side Rendering (SSR).

SSR vs. CSR What’s the Difference?

The key difference between CSR and SSR is the placement of the page’s rendering. The page is rendered on the server side via SSR, while the page is rendered on the client side using CSR. Client-side routing is managed dynamically, without the need to reload the page each time the client requests a change route.

React vs Next.js Performance

Because of static sites and server-side rendering, Next.js apps are lightning fast. They work by default, due to a slew of performance-enhancing technologies including Image Optimization, which arrived in Next 10.

If you use Next.js, you’ll get automated server rendering and code splitting. Furthermore, SSR (Server Side Rendering) will significantly increase your application’s speed.

When it comes to React, there are a few factors that rule it out of the discussion. It only supports client-side rendering out of the box, which is insufficient if you want to construct a high-performance application.

Conclusion on React vs Next.js

In their own ways, both React and Next.js provide excellent developer experiences. React allows you to build things the way you want them to be built and is backed by a large community. Next.js helps to save time by providing a variety of tools and conventions comes equipped, and it’s backed by a strong open source community.

Both React and Next.js are simple to get started with in terms of tools. In NextJs Beyond the initial project, finding help is quite simple, whether in the documentation or through online community.
React is a fantastic complement to any project, and it has the ability to scale if given the chance. Because React is a library, it is more versatile than Next.js. It is up to the developer to decide how to apply it.
