Next.js Tutorial 2025

What is Next.js?

Next.js is a powerful React framework that enables developers to build fast and scalable web applications. It provides features such as server-side rendering (SSR), static site generation (SSG), and API routes, making it a popular choice for many developers.

What is a Framework?

A framework is a collection of pre-written code that provides a structure to develop applications. It offers tools, libraries, and best practices for addressing common tasks. It allows developers to build upon its architecture instead of coding everything from scratch.

Example: Next.js itself is a framework that provides a structure for building React applications.

What is a Library?

A library is a collection of code that developers can use to perform specific tasks. Libraries can be used in various applications without concern for the overall structure of the app. Developers choose when and how to use these libraries.

Example: React is a library for building user interfaces, while Next.js is a framework that utilizes React to build web applications.

Differences Between Frameworks and Libraries

The primary difference between frameworks and libraries is who is in control. When you use a library, you are in charge of the flow of the application, and you can call the library's functions when needed. In contrast, a framework dictates the structure and flow of the application, calling your code when necessary.

```

Important Features of Next.js

Server-Side Rendering (SSR): This allows pages to be pre-rendered on the server for faster initial loading.
Static Site Generation (SSG): Pre-rendering pages at build time for faster performance.
API Routes: Build backend functionality into your Next.js application.

Example: Creating a Simple Page

Let’s create a simple page in your Next.js application.

Open the pages directory.

Create a new file called about.js.

export default function About() {
  return <h1>About Page</h1>;
}

Visit http://localhost:3000/about in your browser.

Q1: What is SSR?
A1: Server-side rendering (SSR) means that the server generates the web page on the fly and sends the fully rendered HTML to the client.

Q2: How do I deploy my Next.js app?
A2: You can deploy your Next.js application using platforms like Vercel, Netlify, or Heroku.

Q3: Is Next.js SEO-friendly?
A3: Yes! Next.js provides excellent support for SEO through server-side rendering and static site generation.
