What is React?

React is one of the most popular open-source JavaScript libraries used for building user interfaces (UIs) for web applications.

Developed by Facebook, React focuses on creating reusable UI components that can efficiently update and render when the application´s data changes. Its component-based architecture allows developers to build complex UIs by composing smaller, reusable components.

React uses a virtual DOM (Document Object Model) for efficient rendering and provides a declarative syntax that makes it easier to manage the application state and handle UI updates. 

Why Use React?

React’s popularity as the top front-end tool, used by over 82% of developers surveyed in State of JS 2022, is maintained by its component-based architecture for reusable UIs, efficient virtual DOM for performance, declarative syntax for code clarity, and one-way data flow for stability. React Native extends its capabilities to mobile app development, while JSX syntax integrates HTML with JavaScript seamlessly. React hooks further enhance functionality, allowing for state and lifecycle features in functional components, solidifying its first-place standing since 2016.

When to Use React?

React is a versatile library used for many different types of projects. These are its more popular uses:

• Single-page applications (SPAs) – React is often used to build SPAs where the application runs entirely in the browser. 

• User interfaces for web applications – React’s component-based architecture and reusable UI components make it ideal for developing complex user interfaces.
• Mobile applications – React Native, a framework based on React, allows developers to build native mobile applications for iOS and Android platforms using JavaScript. 
• Progressive web applications (PWAs) – React is a popular choice for building PWAs, which are web applications that provide an app-like experience with offline support, push notifications, and native-like performance. 
• Real-time collaboration tools – React’s ability to handle real-time updates and its efficient virtual DOM diffing algorithm makes it suitable for building real-time collaboration tools. 
• Interactive data-driven interfaces – React’s ability to efficiently manage and update the user interface based on changing data makes it a good choice for data-driven applications.
• Component libraries and UI frameworks – React’s component-based architecture makes it an excellent choice for creating reusable components and building component libraries. 
• Integration with existing websites or applications – React can be integrated into existing websites or applications without requiring a full rewrite.

6 Key Differences Between Next.js vs. React

1. Performance

In terms of performance, Next.js takes the lead as it provides additional optimization that enhances the performance of web applications compared to React alone.

As Next.js has built-in support for server-side rendering SSR, it can improve the initial page load time and provide better-perceived performance in content-heavy websites. React on its own. It focuses mostly on client-side rendering, where the initial HTML is minimal, and the bulk of rendering work is done on the client’s browser.

Additionally, Next.js automatically performs code splitting, breaking down the JS code into smaller chunks that are loaded on demand. This automatically speeds the initial page loads as only the necessary code is loaded. React, by itself, doesn’t provide these optimizations out of the box. 

Another key feature of Nextjs in terms of performance is its built-in support for static site generation, where the HTML pages are generated at build time. This translates into fast page loads as the pre-rendered HTML can be served directly from a CDN without JS execution. React does not have native support for SSG, although developers can use third-party tools like Gatsby.

React uses client-side navigation, which results in faster subsequent page transitions, as only the necessary components are re-rendered. Nextjs supports both the client and server side, which gives more flexibility in choosing the appropriate navigation strategy based on your application needs. 

Here are two examples that showcase the Next js vs. React SSR and CSR differences: 

Client-side Rendering (CSR) in React:

import React from 'react';

const Counter = () => {

const [count, setCount] = React.useState(0);

const incrementCount = () => {

setCount(count + 1);

};

return (

<div>

<p>Count: {count}</p>

<button onClick={incrementCount}>Increment</button>

</div>

);

};

export default Counter;

As seen above, the Counter component uses React’s useState hook to manage the count state. The count is updated in the client’s browser, and the UI is re-rendered accordingly whenever the user clicks the “increment” button. 

Server-side Rendering (SSR) in Next.js:

import React from 'react';

const Counter = () => {

const [count, setCount] = React.useState(0);

const incrementCount = () => {

setCount(count + 1);

};

return (

<div>

<p>Count: {count}</p>

<button onClick={incrementCount}>Increment</button>

</div>

);

};

export default Counter;

In Next.js´s code, the Counter component is the same as the React example. But, with Next. jsm, this component can be rendered on the server and sent to the client as pre-rendered HTML. This server-side rendering allows the user to see the initial HTML with the current count value without waiting for JS to execute and render the component on the client side. As a result, there´s improvement in the initial page load time and enhanced performance.

2. Seo

In terms of SEO (Search Engine Optimization), both Next.js and React can be optimized for search engines. However, Next.js has some built-in advantages that make it easier to achieve results. Here´s a breakdown of how it works in both NextJS and React.

Next.js:

Next.js has strong support for SEO out of the box, mostly due to its server-side rendering capabilities. With it, the framework can generate and serve fully rendered HTML pages to search engine crawlers that ensure that search engineers understand and index the content (this is fundamental to improving the discoverability of websites in search engine results).

Additionally, Next.js also allows you to customize data such as:

• Page titles
• Meta description
• Open graph tags

How does this help SEO? By managing these metadata elements, you can optimize how your website appears in search engine result pages (SERPs) and social media when your pages are shared.

React:

Although React does not provide built-in-server-side rendering capabilities, it’s still possible to achieve good SEO results.

A common approach is using isomorphic rendering, also known as hybrid rendered, where server sider endearing is selectively applied to specific pages or components. This allows you to generate server-rendered HMTL for pages or content that need better SEO visibility. 

3. Router

Next.js and React Router are used to handle Routers in React applications, but they have different purposes and distinct features. 

In the case of Next.js, it provides a built-in routing solution that means that you don’t require the use of any additional library like React router. Next.js offers both client-side and server-side routing, allowing you to handle routing logic on the server or client. 

The framework also supports dynamic routing that enables the creation of dynamic URLs with parameters. Next.JS’s routing features are tightly integrated into the framework, making it convenient to handle routing in the context of a Next.js application. 

React Router, on the other hand, is a standalone library specifically designed to handle routing in Rect applications. It’s not a complete framework like NextJS, but it’s a flexible and powerful routing solution. It offers a declarative approach to routing and provides features and components suitable for different scenarios. 

Furthermore, React Router allows you to define routes, handle navigation, and pass parameter URLs. It also supports both client-side routings with browser history and server-side rendering with StaticRouter or Browser Router components. 

Other features provided by React Router are nested routes, route, guarding, and URL parameter parsing, which gives React developers full control over the application’s routing behavior.

Still, trying to decide when to use Next.js vs. React Router?

Next.js Router	React Router
Excellent choice when you need a full-stack framework with built-in routing, server-side rendering, and optimizations like code splitting and prefetching	Great option if you´re already using React and need a standalone option with flexible features.
Well-suited for building server-side applications or static websites where performance and SEO are relevant factors.	Suitable for client-side routing in single-page applications or when you need full control of your application´s routing behavior.

4. Typescript

NextJS and React can both be used with TypeScript. Here´s how they differ in terms of TypeScript integration.

NextJS with Typescript: 

Next.js provides excellent support for TypeScript out of the box. Its project setup includes built-in Typescript support that allows you to write Next.js applications using TypeScript from the start. 

The framework also includes TypeScript types for its API routes, server-side rendering (SSR), and other specific features that make it easy to build Next.js applications with type safety. 

When using Next.js with TypeScript, you can create TypeScript-based pages, API routes and components. Next.js automatically recognizes the file extensions like .tsx and .ts, enabling you to write JSX/TSX syntax and define types for props, state, and other entities within your Next.js components.

React with TypeScript:

React has solid support for TypeScript and provides type definitions for its core library. When using React with TypeScript, you can define types for your components, props, state, and other entities, which helps catch type errors during development and improves code and maintainability.

TypeScript allows you to enforce type safety and provides better tooling within your React projects, such as autocompletion and static analysis. 

To use React with TypeScript, you need to install the required TypeScript packages and configure the TypeScript compiler in your project. Once set up, you can start writing React components using TypeScript syntax, define prop types using interfaces or types, and benefit from the additional type checking and documentation provided by TypeScript. 

5. Popularity

Both NextJS and React are widely used in the development community. However, they have distinct levels of popularity. 

React has gained significant popularity, and according to Github, it is stated by far the most popular front-end framework/library. It is also more “wanted” than most frameworks and libraries. 

The library has been widely adopted by major companies, including Instagram, Airbnb and Netflix, which has contributed to its widespread popularity. 

NextJS has gained more visibility in recent years, and some developers have even called it “React´s killer,” but data still shows that React is still far away from being overthrown. The reason is simple: it has numerous features and flexibility that can be combined with a wide range of other technologies.

According to the State of Frontend report, React is the most used and liked framework (76.2%) and NextJS is in second place with 43.1%.

6. Documentation 

When comparing the documentation for Next.js and React, both frameworks have comprehensive resources available online.

Next has a well-documented website that is a useful resource for developers. It covers various topics, including installation, setup, routing, data fetching, styling, and more. It also provides detailed explanations with code examples and usage guidelines for each feature and API offered by NextJS.

The NextJS documentation includes tutorials and guides users to understand how to build specific types of applications or implement common functionality. 

React´s documentation is considered one of the best in the web development community. It covers everything developers need to know to learn React starting from the beginner level to more advanced topics. 

Besides providing clear explanations and code examples, the documentation includes interactive playgrounds that allow developers to experiment and understand more about React´s concepts and APIs.
