Next.js Tutorial

Next.js is a powerful React framework for building fast, scalable, and SEO-friendly web applications. It provides built-in features like server-side rendering, static site generation, routing, and API handling to make development easier and production-ready. It's:

• Built on React, making it easier to create modern, component-driven UIs.
• Server-Side Rendering (SSR) & Static Site Generation (SSG) improves SEO and performance by pre-rendering pages.
• Offers automatic bundling, code splitting, and asset optimization.
• Suitable for both small projects and enterprise-grade applications with full-stack support.

Why learn Next.js?

Next.js offers several advantages over traditional React development:

• Full-Stack Capabilities – Build frontend + backend APIs in one framework.
• Performance – Includes optimizations like code splitting, image handling, and caching by default..
• Industry Demand – Used by top companies (Netflix, TikTok, Uber, etc.).
• Future-Proof – Backed by Vercel and rapidly evolving with strong community support.

Creating Your First Next.js Page :

// pages/index.js

export default function Home()
{
    return (<div><h1>Welcome to the
                Next.js Tutorial</h1>
        </div>);
}

It will start a server, and when you visit http://localhost:3000, it will display

Welcome to the Next.js Tutorial

Code Explanation :

• The file index.js inside the pages folder acts as the root route (/).
• The Home function is exported as the default export, making it accessible as a page.
• There is no need for manual routing configuration; Next.js handles it automatically.

In this Next.js Tutorial, we'll learn all the basic to advanced concepts such as Routing, Data Fetching, Environment Variables, Meta Tags, Static File Serving, Pre-Rendering, etc.

Features of Next.js

Next.js is a React framework that extends React's capabilities to build server-rendered and statically generated web applications. Here are some of its key features:

• Server-side Rendering (SSR): This improves SEO and initial load performance by rendering pages on the server. Content is already available for search engines to index, and users see a fully rendered page on the first load.
• Static Site Generation (SSG): This pre-renders pages at build time, making them super fast to load. Ideal for content that changes infrequently, like blog posts or landing pages.
• Automatic Code Splitting: This breaks down your application code into smaller bundles, improving load times by only loading the code needed for the current page.
• Data Fetching: Next.js offers several ways to fetch data, including getStaticProps for fetching data at build time and getServerSideProps for fetching data on each request. This flexibility allows you to choose the most appropriate method for your specific needs.
• Routing: Routing is simplified in Next.js. It automatically creates routes based on the file structure of your pages directory, making it easy to manage your application's URL structure.
• Image Optimization: Next.js automatically optimizes images, including resizing and compressing them, for faster loading times and improved SEO.
• Built-in CSS and JavaScript Bundling: Next.js takes care of bundling and optimizing your CSS and JavaScript code, streamlining the development process.
• API Routes: Next.js allows you to create serverless functions directly within your application using API routes. This lets you add backend functionality to your React application without needing a separate server
