Gatsby

Overview

Gatsby is a tool that helps professional developers efficiently create maintainable and highly-performant websites. It allows developers to pull in data from various sources, whether it’s Markdown files, headless CMS platforms like Contentful or WordPress, or REST or GraphQL APIs. Gatsby sites are not limited to being static websites but can also be fully functional React apps, giving developers the ability to create dynamic web applications such as blogs, e-commerce sites, and user dashboards. This tool provides performance optimization features by automating code splitting, image optimization, lazy-loading, prefetching resources, and more. Additionally, Gatsby sites can be hosted on a CDN, reducing hosting costs. Gatsby’s Valhalla Content Hub allows developers to bring its centralized data layer to any project, making it accessible via a unified GraphQL API.

Features

• Load Data From Anywhere: Gatsby allows developers to pull in data from various data sources, including Markdown files, headless CMS platforms, and REST or GraphQL APIs.
• Go Beyond Static Websites: Gatsby sites are not limited to being static websites but can also be fully functional React apps, enabling the creation of dynamic web applications.
• Choose your Rendering Options: Developers have granular control over rendering options, including Deferred Static Generation (DSG), Server-Side Rendering (SSR), and Static Site Generation (SSG), on a per-page basis.
• Performance Is Baked In: Gatsby automates performance optimization features such as code splitting, image optimization, lazy-loading, and prefetching resources to ensure fast site performance without manual tuning.
• Use a Modern Stack for Every Site: Gatsby sites are built using React and GraphQL, providing a uniform workflow for developers regardless of the data source.
• Host at Scale for Pennies: Gatsby sites can be hosted on a CDN, eliminating the need for servers and reducing hosting costs.
• Use Gatsby’s Centralized Data Layer Everywhere: Developers can bring Gatsby’s data layer to any project with Valhalla Content Hub, making it accessible through a unified GraphQL API.

Installation

To get started with Gatsby, follow these steps:

1. Initialize a new project using the command: gatsby new my-gatsby-site
2. Move into the project directory: cd my-gatsby-site
3. Start the development server: gatsby develop
4. Open the source code in your preferred code editor and start editing the files in the src directory.

Your Gatsby site will be running at http://localhost:8000, and any changes you make to the source code will be reflected in real-time.

Summary

Gatsby is a powerful tool for professional developers to create maintainable and highly-performant websites. It allows developers to easily pull in data from various sources, build dynamic web applications, and optimize performance without manual tuning. With its centralized data layer and support for modern web technologies like React and GraphQL, Gatsby provides a unified workflow for developers. Hosting Gatsby sites on a CDN helps reduce hosting costs while ensuring scalability. Overall, Gatsby is a versatile and efficient solution for building content-rich websites.
