Plugin & Theme Tutorials
Gatsby plugins are Node.js packages that implement Gatsby APIs and are commonly installed through a registry like npm. Common use cases for Gatsby plugins include data sourcing and hooking into lifecycle methods.
Gatsby themes are a type of plugin that includes a gatsby-config.js file and adds pre-configured functionality, data sourcing, and/or UI code to Gatsby sites. Themes might pre-bundle plugins and configure them so users don’t have to, providing a nice abstraction that can be installed and updated as a package.
