Concepts specific to working within Gatsby: components, GraphQL, image optimization, builds, plugins, starters, data fetching, rendering options.
React's component architecture simplifies building large websites by encouraging modularity, reusability, and clear abstractions.
Gatsby uses GraphQL to provide a uniform way for page and StaticQuery components to declare what data they and their sub-components need.
Image optimization includes fetching “above the fold” images immediately, providing a placeholder, and minimizing image file size.
Gatsby's build process is a compilation step turning your code and content into static HTML files that can be served on a CDN.
In the Gatsby ecosystem, there's more than one way to build a site. This guide walks through some of the differences between plugins, themes, and starters.
Choose between generating content at build time, making calls to external services at runtime, or a hybrid approach.
The differences between Static Site Generation, Deferred Static Generation, and Server-Side Rendering.
Partial Hydration enables you to selectively add interactivity to your otherwise completly static app. This results in improved frontend performance while keeping the benefits of client-side apps. Gatsby uses React Server Components to achieve this.
