gatsby-plugin-feed-generator
A Gatsby plugin to generate JSON Feed and RSS feeds for generated Gatsby sites.
Installation and Setup
To get started, install via yarn or npm:
yarn add gatsby-plugin-feed-generator
Basic setup requires the following minimum siteMetaData located in your gatsby-config.js
file:
siteMetadata title: 'Gatsby' description: 'A static site generator' siteUrl: 'https://gatsbyjs.org' author: 'Author Name'
To activate and configure the plugin add it to the plugins array in the gatsby config as you would any other plugin.
plugins: resolve: 'gatsby-plugin-feed-generator' options: //...
Version 1 allowed for using the built-in config, but for version 2+ you'll need to provide a siteQuery, one or more feeds, and a normalize function for each feed. This tells the plugin how to map your data onto the feeds.
Here is an example using gatsby-transformer-remark
's allMarkdownRemark
as a source for your content:
// gatsby-config.js siteMetadata title: 'Gatsby' description: 'A static site generator' siteUrl: 'https://gatsbyjs.org' author: 'Author Name'plugins: resolve: 'gatsby-plugin-feed-generator' options: generator: `GatsbyJS` rss: true // Set to true to enable rss generation json: true // Set to true to enable json feed generation siteQuery: ` { site { siteMetadata { title description siteUrl author } } } ` feeds: name: 'feed' // This determines the name of your feed file => feed.json & feed.xml query: ` { allMarkdownRemark( sort: {order: DESC, fields: [frontmatter___date]}, limit: 100, ) { edges { node { html frontmatter { date path title } } } } } ` { return allMarkdownRemarkedges }
The important takeaway from the normalize function is the mapping of your graphql data onto the title, date, url, and html fields. If you have a special way of building urls, this is the place to handle that transformation before sending it to the plugin.
Recipes
Above we saw markdown used, however other formats should work as well. Here's an example using MDX:
//... feeds: name: 'mdx-feed' query: ` { allMdx( sort: {order: DESC, fields: [frontmatter___date]}, limit: 100, ) { edges { node { html frontmatter { date path title } } } } } ` { return allMdxedges }
