NextJS is a React framework developed by Vercel that extends the functionality of the React library. It is an open-source framework that allows for the creation of speedy and SEO-friendly React applications without requiring any configuration. In a typical React application, the rendering process occurs on the client-side, which means the browser first loads an HTML page without any pre-rendered content.

It then fetches the JavaScript file, which contains the React components, to display the content on the webpage. Next.js simplifies this process by enabling server-side rendering, route pre-fetching, smart bundling, and other features, making it easier to build production-ready applications with an enhanced user experience.

What Can You Build with Next.js?

Companies such as Vercel, Netflix, Hulu, and Expo use Next.js for their applications. It lets you build your web apps with Next. Below are some of the features in which Next.js is beneficial to you:

Landing pages: If you're in search of a platform to create engaging landing pages, then Sitecore XM is an excellent choice. Marketers swear by it because landing pages are often the first impression visitors have of your website.

Marketing websites: For websites focused on marketing, Next.js is the ideal solution. It excels in scenarios where users may access the website using slower devices. If you pre-render the website on the server, loading time improves significantly.

SEO-friendly web applications: If you want your website to rank in search results, then Next.js should be your ally. It provides excellent support for SEO, letting you optimize titles and keywords, resulting in faster website performance and better visibility in top search rankings.

Example:

import Link from "next/link";

const Header = () => {

return (

<span>

</span>

<span>

<Link href="/episodes">Episodes</Link>

</span>

<span>

<Link href="/season2">Season 2</Link>

</span>

<span>

<Link href="/quotes">Quotes</Link>

</span>

</nav>

);

};

export default Header;

What is ReactJS?

ReactJS is an open-source library built by Facebook for creating the best user interface web applications. The library allows the developers to write code and use it whenever they want an unlimited number of times. The library uses JavaScript to create its components but can also be created by using TypeScript. It’s quite popular among developers but many of them are now moving to the next popular framework NextJS.

What Can You Build with ReactJS?

React is an extremely popular library also built by Facebook. Airbnb, New York Times, Instagram, and Whatsapp use ReactJS in their tech stack. Below are some of the features in which ReactJS is useful for you:

Social media sites: Social media websites can be difficult to build with any framework since they require various features to be used multiple times. React can make your process faster as it uses reusable components for the same.

News sites: It can also build news applications quickly with excellent features and UI.

Example:

import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';

export default function App() {
return (
<Router>
<section>
<Header />
<Routes>
<Route path="/" element={<HomePage />} />
<Route path="/episodes" element={<EpisodesPage />} />
<Route path="/season2" element={<Season2Page />} />
<Route path="/quotes" element={<QuotesPage />} />
</Routes>
</section>
</Router>
);
}

What is AngularJS?

AngularJS was developed around 2009 by Misko Hevery and Adam Abrons and is now maintained by Google. AngularJS is a JavaScript open-source front-end framework for developing single-page web applications (SPAs). It is a continuously growing and expanding framework which provides improved ways for developing web applications.

Why use AngularJS?

Easy to work with: All you need to know is the basics of HTML, CSS, and JavaScript, and you’re good to go.
Saves time: AngularJs allows you to work with components and hence you can reuse them which saves time and unnecessary code.
Ready to use template: AngularJs is plain HTML with an HTML template. It first passes it to the DOM and then the AngularJS compiler. It traverses the templates before they are ready to use.

Example:

<!DOCTYPE html>

<html>

<head>

<title>AngularJS</title>

<script src=

"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js">

</script>

</head>

<h2 style = "color:green">Geeksforgeeks</h2>

<p>{{ name }} is the portal for geeks.</p>

</div>

</body>

</html>

Comparison between React, Next, and Angular

Field	React.js	Next.js	Angular
Used as	React.js is a JavaScript library. As it indicates React updates only the virtual DOM that is present and the data flow is always in a single direction.	Next.js is a framework for server-rendered or statically pre-rendered react applications, taking advantage of flexible configuration and dependency management.	Angular is a framework. It updates the Real DOM and the data flow is ensured in the architecture in both directions.
Released	It was released in 2013.	It was released in 2016.	It was released in 2010.
Architecture	React.js is more simplified as it follows MVC i.e., Model View Control. This, like Angular, includes features such as navigation but can be achieved only with certain libraries like Redux and Flux. Needs more configuration and integration.	Next.js uses MVC architecture.	The architecture of Angular on the other hand is a bit complex as it follows MVVM models i.e., Model View-ViewModel. This includes many tools and other features required for navigation, routing, and various other functionalities.
Performance	React.js holds JSX hence the usage of HTML codes and syntax is enabled. But this doesn’t make ReactJS a subset of HTML. This is purely JavaScript-based.	With Next.js, all heavy lifting is done at compile time, so pages can load up to 10x faster on Next.js than they do on Angular.	Angular, on the other hand, is a mere subset of HTML.
Written	React.js written in JavaScript.	Next.js written in TypeScript.	Written in Microsoft’s Typescript language, which is a superset of ECMAScript 6 (ES6).
Dependency Injection	React.js does not use the Dependency Injection concept.	Next.js uses the Dependency Injection concept.	In Angular, the Hierarchical Dependency Injection system is used.
Routing	Routing is not easy in React JS.	Next.js requires nested routes.	Routing is comparatively easy compared to React JS.
Scalability	It is highly scalable.	It is highly scalable.	It is less scalable than React JS.
Data Binding	It supports Uni-directional data binding which is one-way data binding.	It supports Uni-directional data binding which is one-way data binding.	It supports Bi-directional data binding that is two data binding.
DOM	It has a virtual DOM.	It has a virtual DOM.	It has a regular DOM.
Testing	It supports Unit Testing.	Next.js applications consist of running e2e tests.	It supports both Unit testing and Integration testing.

Conclusion

ReactJS, AngularJS, and NextJS each offer unique benefits for web development. ReactJS is highly flexible and widely adopted, AngularJS offers a comprehensive framework with robust features, while NextJS is good for server-side rendering and SEO.
