Next.js for beginers

Introduction to Next.js

Next.js is a popular open-source framework built on top of Node.js and React. It allows developers to build server-side rendered (SSR) React applications with ease. Next.js provides a set of tools and conventions that simplify the development process and allow developers to focus on building great user experiences.

Why use Next.js?

Next.js has several advantages that make it a popular choice for building React applications:

  • Server-side rendering: Next.js allows developers to build applications that can be rendered on the server-side, improving performance and providing better SEO.

  • Automatic code splitting: Next.js automatically splits code into smaller chunks, allowing for faster initial load times and better performance.

  • Routing: Next.js provides a simple and intuitive API for handling routing, making it easy to build complex applications.

  • Static site generation: Next.js supports static site generation, allowing developers to generate static HTML files that can be deployed to a content delivery network (CDN) for even better performance.

Getting started with Next.js

To get started with Next.js, you first need to create a new project. You can do this by running the following command in your terminal:

npx create-next-app my-app

This will create a new Next.js project in a directory called my-app.

Once you have created your project, you can start the development server by navigating to the project directory and running the following command:

npm run dev

This will start the development server and allow you to view your application in the browser.

Next.js provides a simple and intuitive API for handling routing. You can define routes in your application by creating files in the pages directory. For example, if you create a file called pages/about.js, you can access the about page of your application by navigating to /about in the browser.

Next.js also supports automatic code splitting, which allows you to split your code into smaller chunks for better performance. You can enable automatic code splitting by using the dynamic method provided by Next.js. For example, you can use the following code to lazy load a component only when it is needed:

import dynamic from 'next/dynamic';

const MyComponent = dynamic(() => import('../components/MyComponent'));


Next.js is a powerful and popular framework for building server-side rendered React applications. It provides many advantages, including server-side rendering, automatic code splitting, and simple routing. With a simple and intuitive API, Next.js makes it easy to build complex applications and deliver great user experiences.
