Part I: Getting Started with Next.js Next.js is a popular React-based framework for building server- rendered applications. It provides a number of features out of the box, such as automatic code splitting, server-side rendering, and static site generation. To get started with Next.js, you'll need to have Node.js and npm installed on your machine. Once you have those, you can create a new Next.js project by running the following command: This will create a new Next.js project in a directory called Once the project is created, you can navigate to the project directory and start the development server by running: This will start the development server at and you should see the default Next.js homepage in your browser. From here, you can start building your Next.js application by creating pages and components. Pages in Next.js are React components that are automatically mapped to routes based on their file name. For example, if you create a file called it will automatically be mapped to the /about route. Components in Next.js are just like regular React components, but they can be shared across pages and can also be used to define global styles and layouts.

Chapter 1: Introduction to Next.js Next.js is a framework for building server-side rendered and statically generated web applications. It was created by the team at Vercel (formerly Zeit), and has gained popularity due to its ease of use, powerful features, and strong community support. Next.js provides several features out of the box that are not available in vanilla React applications. These include: Automatic code splitting: Next.js automatically splits your code into smaller chunks that are loaded on demand, improving the initial load time of your application. Server-side rendering: Next.js can render your React components on the server, improving the initial rendering speed and providing better SEO. Static site generation: Next.js can generate static HTML files for your application, enabling fast page loads and reducing server costs. Automatic optimization: Next.js automatically optimizes your images, CSS, and JavaScript for faster loading times. API routes: Next.js provides a simple way to create serverless API endpoints that can be used to fetch and manipulate data. TypeScript support: Next.js provides first-class support for TypeScript, making it easy to build type-safe applications. Next.js also provides an easy-to-use development experience. You can use the built-in development server to preview your

1.1. Why use Next.js? There are several reasons why developers choose to use Next.js for building web applications: Server-side rendering: Next.js allows you to render your React components on the server, which can improve the initial rendering speed and provide better SEO. Automatic code splitting: Next.js automatically splits your code into smaller chunks that are loaded on demand, which improves the initial load time of your application. Static site generation: Next.js can generate static HTML files for your application, enabling fast page loads and reducing server costs. Simple API routes: Next.js provides a simple way to create serverless API endpoints that can be used to fetch and manipulate data. TypeScript support: Next.js provides first-class support for TypeScript, making it easy to build type-safe applications. Easy development experience: Next.js provides an easy-to-use development experience, with a built-in development server for previewing changes in real-time. Easy deployment: Next.js can be easily deployed to the Vercel platform, making it simple to scale your application and manage your infrastructure.

1.2. Understanding the benefits of server-side rendering Server-side rendering is the process of rendering web pages on the server, instead of the client's browser. When a user visits a server-side rendered page, the server generates the HTML, CSS, and JavaScript for the page and sends it to the client's browser. There are several benefits to using server-side rendering in your web applications: Improved initial rendering speed: With server-side rendering, the initial HTML is already available to the user when they first visit the page, which means the page can be rendered much faster. Better SEO: Server-side rendering can also improve your site's search engine optimization (SEO) by ensuring that search engines can crawl and index your pages more easily. Accessibility: Server-side rendering ensures that the content is visible to all users, even if they are using a device or browser that does not support JavaScript. Improved performance on slow devices: Server-side rendering can improve the performance of your site on slow devices, as the server can handle much of the heavy lifting and reduce the load on the client's browser. Next.js provides a simple and powerful way to implement server-side rendering in your React applications. By leveraging Next.js, you can build fast, scalable, and SEO-friendly web applications that provide a great user experience on all devices.

1.3. Exploring the Next.js ecosystem The Next.js ecosystem consists of several tools, libraries, and resources that can help you build better web applications. Some of the most popular ones are: Vercel: Vercel is the company behind Next.js, and it provides an easy way to deploy your Next.js applications to the cloud. Vercel also provides a wide range of features such as global CDN, serverless functions, and automatic SSL. Next.js plugins: Next.js plugins are reusable pieces of functionality that can be added to your Next.js application. They can be used to add features such as internationalization, analytics, and authentication. Tailwind CSS: Tailwind CSS is a popular utility-first CSS framework that can be used to style your Next.js application. It provides a large set of pre-built styles that you can use to create beautiful and responsive UI components. SWR: SWR is a lightweight library for managing data fetching in Next.js applications. It provides a simple API for caching, revalidation, and error handling. TypeScript: TypeScript is a strongly typed superset of JavaScript that can be used to build type-safe Next.js applications. It provides advanced features such as interfaces, enums, and type guards, which can help you catch errors early and improve code quality.
