Follow these articles to install depending on your systemNext.js InstallationLet us now take a look at our first code example. JavaScript // 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 displayWelcome to the Next.js TutorialIn this exampleThe 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.Why learn Next.js?Next.js offers several advantages over traditional React development:Built-in Routing and SSR: Unlike React, which lacks native routing, Next.js provides seamless routing functionality out of the box. Additionally, it supports server-side rendering, improving performance and SEO.Faster Development: Next.js accelerates development by offering built-in features and conventions. Developers can focus on building features rather than configuring complex setups.SEO Optimization: Next.js enhances SEO by addressing slow rendering and loading times associated with client-side rendering. Its SSR capabilities ensure that search engines can efficiently crawl and index your content.Additionally, Next.js mitigates slow rendering and loading times inherent in client-side rendering, important for optimizing SEO performance. Its integration of server-side rendering out of the box enhances overall development efficiency and user experience.Next.js Tutorial Prerequisites: HTML, CSS, JavaScript and ReactNext.js BasicLearn the core features and structure of Next.js to start building full-stack applications.Next.js IntroductionNext.js Create Next AppNext.js 14 Folder StructureNext.js src DirectoryInstall & Setup Tailwind CSS with Next.jsNext VS ReactHow to import image in Next.js?How to add stylesheet in Next.js?How to start Next.js server?Next.js Dynamic ImportHow to use Material-UI with Next.js?Next.js RoutingHow to Integrate MongoDB in Next.js Next.js RoutingNext.js provides automatic routing based on the file structure in the pages directory.

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.Next.js vs ReactLet’s compare Next.js with React to see how they differ in terms of flexibility and use cases.FeatureNext.jsReactTypeFrameworkLibraryLearning curveSteeper (due to additional features)EasierFlexibilityLess flexible (opinionated)More flexibleCode complexityLess code needed (built-in features)More code needed (external libraries)RenderingServer-side rendering (SSR) optionalClient-side rendering (CSR) by defaultSEOBetter SEO due to pre-rendered contentCan be achieved with additional librariesApplicationE-commerce, marketing websites, blogsComplex web applications, social media, dashboard Comment More infoAdvertise with us Next Article Next.js Introduction kartik Follow Improve Article Tags : Next.js Next.js Similar Reads Next.js Tutorial Next.js is a popular React framework that extends React's capabilities by providing powerful tools for server-side rendering, static site generation, and full-stack development.
