Gatsby is an open-source framework for building websites with React, GraphQL and a large ecosystem of plugins. It is often used for blogs, documentation and marketing sites that pull content from Markdown files or a headless CMS. Pages are usually generated at build time, which makes sites fast but means features like RSS feeds must be produced during the build as well. The official gatsby-plugin-feed package is the usual way to add a feed. Posts under this tag cover Gatsby feeds, their configuration and how to use them for syndication and automatic social posting.
