Gatsby Introduction

Gatsby is a free and open-source framework based on React that helps developers build blazing-fast websites and apps. Gatsby’s sites are fully functional React apps, so you can create dynamic web applications that are fast, responsive, and secure.

Introduction: With Gatsby, you can build static websites, hybrid static & server-rendered sites, and full React applications. Gatsby’s speed is its main selling point. It uses various techniques to optimize your websites, such as code splitting, server-side rendering, and prefetching resources. All of these performance optimizations make Gatsby websites load extremely fast, which is important for both users and search engines.

Another great benefit of Gatsby is its ease of use. Setting up a basic Gatsby website is a breeze, and there are many starter templates and themes available to help you get started quickly.

If you’re looking for a fast, easy-to-use framework to build websites and applications, Gatsby is a great option. In this article, we’ll learn how we can install and use Gatsby on our device to create fast web applications.

Steps to Install and Run Next.js Application:

Step 1: Installation of Gatsby, require npm and node.js. You can install node.js from here. Confirm the installation by running these commands on the terminal.

node -v
npm -v

Step 2: Now run the below code in the terminal to create a new Gatsby site.

npm init gatsby

It will ask the name of your application and the project folder. For this example, we are using “gfg” as the name.

Step 3: Move to the application folder that you just created using the below code:

cd gfg

The project structure will look something like this.

Step 4: Run the below command in the terminal to start the development server.

npm run develop

Go to ‘http://localhost:8000’ in the browser, and you can see your application.

Step 5: Now we are going to change the content on the homepage. For this, add the below content in the ‘index.js’ file.

index.js

import * as React from "react"

const IndexPage = () => {
  return (
    <main >
      <h3>GeeksforGeeks - Demo Gatsby Page</h3>
    </main>
  )
}

export default IndexPage

Run the below command in the terminal to start the development server.

npm run develop

Output:
