What is ReactJS?

It is an open-source and free JavaScript library for the front end. It is used to build User Interfaces based on the concept of components. React is used to develop server render, mobile, or single-page applications with frameworks like NextJS.To update the User Interface efficiently, it uses lightweight virtual DOMs representing a real DOM. React only updates the real DOM when required, which makes it a fast and efficient application.

ReactJs VS Next.js: The Key Differences 

  • Performance

Next.js: It automates code splitting and service rendering to improve the development performance of the application. It has numerous performance enhancement features like image optimization. 

ReactJS: It supports only client-side rendering, which does not suffice for the high-performance development of the application.

  • Documentation

Next.js: It provides users with a  “learn-by-doing” tutorial to guide them on Next.js component development, integration, and creation. 

ReactJS: It also offers users a similar design and some introductory activities to explain the fundamentals.

  • Service - Side Rendering

Next.js: It supports SSR by collecting data and rendering every request whenever the developer wants to deliver a distinct view for numerous users.

ReactJS: It does not support SSR, although the developer can enable it. It will consume time and effort to integrate Server-side rendering into the preferred setup and server. Also, there is a high probability that developers might not support it in the following versions. 

  • Developer Community

Next.js: The community is more active in the open-source world, such as GitHub. It has very few conventional exercises. 

ReactJS: It has an active developers community that is ready to provide solutions through videos, tutorials, blogs, and other sources. The developer can also access Stack Overflow to find active community members of ReactJS.

  • Configuration

Next.js: With the help of Next.js, the developer can configure everything, unlike ReactJS. It will permit you to configure files like eslintrc, babelrc, and jest.config 

ReactJS: It doesn't provide support for configuration. You will have to disconnect from the default Create React App; otherwise, modifying the configuration will not be possible. Also, you need to adhere to the existing setups or configure them within CRA's read script.

  • Typescript

Next.js:  It backs Typescript. Next.js supports configuration with touch tsconfiq.json, too. 

ReactJS: It supports Typescript with npx create-reach-app my-app-template Typescript for the CRA Application.

  • Experienced Developers

Next.js: All the Next.js developers should know ReactJS and all the ReactJS developers should be well-versed in Javascript. You can use reactJS without knowing Javascript. But at the same time, you can't use Next.js without knowing ReactJS.

ReactJS: It is very popular among developers across the world. Also, finding experienced developers is comparatively easier than Next.js.

  • Features

Next.js: The developers can leverage features of Next.js to create the following ready-to-go applications such as 

  • Pre-rendering
  • Enhanced development compilation
  • SSR ( Service Side Rendering)
  • Automatic build size optimization
  • Static Export

ReactJS: It can be used to customize any project. ReactJS is extensible, providing routing and libraries with state management patterns like Redux.

Community support

It has a large community for quick support and resources for learning.

Components

They are reusable. The developer can load several pages recurringly while maintaining the characteristics. You can see changes on all pages once you have modified the component.

Customization

You can expand the set of features with the redux tool.

Disadvantages of ReactJS

Potential 

Since React is a UI development library, it needs other tools to leverage its full potential.
