What is Next.js?

Next.js is an open source React framework developed by Vercel that empowers developers to build user friendly & SEO optimized apps. Released in 2016 it has become a favorite for creating dynamic websites & static apps. 

Its standout feature server side rendering ensures faster load times and improved search engine visibility making it perfect for blogs, landing pages and complex applications. Trusted by industry leaders like TikTok, Target, and The Washington Post, Next.js continues to be a top choice for modern web development.

Features of Next JS

Before discussing Next Js vs React lets discuss the main features. Some of the main features of Next JS are as follows:

Hot Code Reloading

With this feature, any changes made to the code are instantly visible in the browser without a full page refresh. This fast refresh process enhances the development experience by making testing and debugging quicker.

Automatic Code Splitting

Next.js automatically divides your JavaScript code into smaller chunks, ensuring that only the necessary code for each page is loaded. This reduces page load times and keeps the application lightweight.

Ecosystem Compatibility

Next.js is designed to work smoothly with the React and Node.js ecosystems allowing developers to use existing skills and tools while gaining the benefits of Next.js specific features.

Server Side Rendering 

SSR allows pages to be rendered on the server instead of the client resulting in faster page loads and improved SEO. This is particularly beneficial for content heavy or dynamic websites.

Static Site Generation 

Pre-renders pages during the build process, serving them as static HTML files. This is ideal for content that doesn’t change frequently, such as blogs or documentation, ensuring quick delivery and reduced server load.

Automatic Routing

Next.js simplifies routing with a file-based system. By creating files in the pages directory, routes are automatically generated, eliminating the need for complex route configurations.

Image Optimization

The built-in next/image component optimizes images by supporting modern formats like WebP, lazy loading, and responsive images. This results in faster load times and better user experiences.

Prefetching

Next.js preloads resources for routes that are within the viewport, ensuring faster navigation when users click on those links.

Font Optimization

The next/font package automatically optimizes fonts, supports Google and local fonts, and eliminates external requests. This leads to better performance and reduced layout shifts.

Script Optimization

The next/script package ensures third-party scripts are loaded efficiently. Developers can choose when and how scripts are loaded using strategies like beforeInteractive or lazyOnload.

Route Handlers

Simplifies server-side operations such as handling HTTP requests, fetching data from databases, and integrating with APIs. It supports HTTP methods like GET and POST for dynamic server-side logic.

React Server Components 

Allows components to be rendered on the server, reducing client-server data fetching trips and improving performance. While server components can’t perform client-side operations, they work well for data-intensive tasks.

What is React?

React is an open source UI library created by Meta (formerly Facebook) to build dynamic, event-driven web applications. It allows developers to write components in JavaScript (or TypeScript) that can be reused across applications, promoting efficiency. Unlike traditional websites, which reload the entire page for data changes, React only re-renders the components affected by the state change, leading to faster updates. React is declarative, meaning developers have full control over the workflow, making it a powerful tool for creating responsive and interactive user interfaces.

Features of React JS

Main features of React JS are as follows:

JavaScript Syntax Extension

JSX is a combination of JavaScript and HTML that makes creating React elements easier. It allows you to embed JavaScript expressions inside HTML-like code. While browsers don’t natively support JSX, it is compiled by Babel into JavaScript, simplifying development. This syntax extension makes the code more readable and familiar for developers who know HTML and JavaScript.

Virtual DOM

The Virtual DOM is a lightweight copy of the real DOM. Instead of updating the entire DOM when a change occurs, React first updates the Virtual DOM and compares it with the real DOM. Only the changed parts are updated, making React more efficient and faster in rendering updates.

One-way Data Binding

In React, data flows in a single direction, from parent components to child components. This simplifies data management because child components cannot directly modify the data they receive; instead, they communicate with the parent to update the state. This one way flow makes application more predictable and easier to debug.

Performance

React use of the Virtual DOM ensures that only the necessary parts of the UI are re-rendered which optimizes performance. By updating only the modified components, React reduces the load on the browser ensuring a faster and smoother user experience.

Component Based Architecture

React structures UIs using reusable components, each managing its own logic and behavior. These components can be nested, reused, and composed to build complex UIs. This modular approach improves code maintainability and allows for better organization in large applications.

Advantages of React
