How to Set up a Gatsby JS Project

Understanding Gatsby.js: Why Use It?

• Static Site Generator: Gatsby transforms your React code into a static HTML, CSS, and JavaScript file collection.
• Performance: Static sites generated by Gatsby deliver lightning-fast load speeds and enhanced user experiences.
• SEO-Friendly: Pre-rendered HTML makes your content easily discoverable by search engines.
• Ideal for Blogs: Gatsby’s strengths and the included ‘blog starter’ make it a popular choice for building blogs and similar content-driven websites.

Prerequisites

• Node.js (version 18 or newer): Download and install from https://nodejs.org/
• npm or yarn (package managers): These are installed along with Node.js.
