Gatsby.js is a modern and powerful Node.js framework for building fast and scalable web applications. It is based on React and GraphQL, and provides a rich set of features and tools for building modern web applications.

In this tutorial, we will show you how to install and set up Gatsby.js on Ubuntu 22.04. We will assume that you have already installed Node.js and npm on your system.

Prerequisites

Before you begin, you will need the following:

• A system running Ubuntu 22.04
• Node.js and npm installed on your system
• A user with administrative privileges on your system

Installing Gatsby.js

To install Gatsby.js on Ubuntu 22.04, you can use the npm package manager. First, open a terminal and run the following command to install the gatsby-cli package globally:

sudo npm install -g gatsby-cli

This will install the Gatsby.js command-line interface (CLI) on your system, which you can use to create, build, and serve Gatsby.js projects.

Creating a New Project

After installing the Gatsby.js CLI, you can create a new Gatsby.js project using the gatsby new command.

To do this, navigate to the directory where you want to create the project and run the following command:

gatsby new my-gatsby-project

Replace my-gatsby-project with the name of your project.

This will create a new Gatsby.js project in the my-gatsby-project directory, and install the necessary dependencies.

Building and Serving the Project

After creating the Gatsby.js project, you can build and serve the project using the gatsby develop command.

To do this, navigate to the root directory of your project and run the following command:

cd my-gatsby-project
gatsby develop

This will start the development server for your project, and open the default home page in your default web browser.

By default, the development server listens on port 8000, so you can access the home page of your project at the following URL:

<http://localhost:8000>

You can make changes to the code of your project, and the development server will automatically rebuild and reload the page.

Conclusion

In this tutorial, you learned how to install and set up Gatsby.js on Ubuntu 22.04. You also learned how to create a new Gatsby.js project, build and serve the project, and make changes to the code.
