Gatsby plugins are Node.js packages that implement Gatsby APIs. For larger, more complex sites, plugins let you modularize your site customizations into site-specific plugins.

There are many types of Gatsby plugins, including data sourcing, SEO, responsive images, offline support, Sass support, sitemaps, RSS feeds, TypeScript, Google Analytics, and more. You can also make your own plugins!

Gatsby themes are a type of plugin that include a gatsby-config.js file and add pre-configured functionality, data sourcing, and/or UI code to Gatsby sites. To learn more about theme use cases and APIs, check out the themes section of the docs. To learn about how plugins differ from themes and starters refer to the Plugins, Themes, & Starters conceptual guide.

Here are the guides in the Plugins section of the docs:
