What is Next.js and how does it work?

Next.js is a React framework that is used for building server-rendered web applications. It combines React, Webpack, and Babel to provide a powerful development environment for creating modern and scalable web applications.

Here's how Next.js works:

1. Server-side Rendering: Next.js enables server-side rendering (SSR), which means that the initial rendering of the application takes place on the server before being sent to the client. This improves performance by reducing the time required to display the content to the user.
2. Automatic Code Splitting: Next.js automatically splits the code into smaller chunks, allowing only the required code to be sent to the client. This ensures that the initial page load is fast, and subsequent page navigations are also optimized.
3. React Components: Next.js uses React for building UI components. It provides a file-based routing system, where each page of the application is represented by a React component.
4. Hot Module Replacement: Next.js supports hot module replacement, which means that the changes made during development are automatically reflected in the browser without requiring a full reload. This significantly speeds up the development process.
5. CSS-in-JS: Next.js supports CSS-in-JS libraries like styled-components and CSS Modules. This allows for writing component-specific styles in JavaScript, which are then automatically scoped and optimized during the build process.
6. API Routes: Next.js provides an API routes feature that allows you to create serverless API endpoints directly within your Next.js application. This makes it easy to handle server-side logic and data fetching without the need for an additional server.

Overall, Next.js simplifies the development process by providing a built-in setup for server-side rendering, code splitting, and other important optimizations. It allows developers to focus on building the application logic and user interfaces while handling the server-side complexities behind the scenes.
