Next.js Tutorial for Beginners

Welcome to this Next.js tutorial for beginners! If you are new to Next.js, you might have heard about it as a powerful framework for building React applications. In this article, we will dive into the basics of Next.js and provide a step-by-step guide for beginners to get started with building applications using Next.js.

Understanding Next.js

What is Next.js?

Next.js is a framework for building React applications that provides many features out of the box, such as server-side rendering, static site generation, and routing. It helps developers to create fast and scalable applications with ease.

Framework vs Library

In the world of software development, a framework is a set of tools and libraries that provide a foundation for building applications. On the other hand, a library is a collection of pre-written code that can be used to perform specific tasks. The main difference between them is that in a framework, the flow of control is dictated by the framework, while in a library, developers make the calls to the library.

Getting Started with Next.js

Now, let's get into the Next.js tutorial for beginners!

Server-Side Rendering (SSR) in Next.js allows you to pre-render React components on the server before sending the HTML to the client. This results in faster page load times and better search engine optimization.

How to Deploy a Next.js Application?

Next.js applications can be deployed to various platforms such as Vercel, Netlify, or custom servers. You can use the next export command to export your Next.js application as static HTML files.

Important to Know

It is important to know that Next.js provides a great developer experience with features like hot module replacement, automatic code splitting, and API routes for serverless functions.
