RSS Plugin #

A pack of plugins for generating an RSS feed (actually an Atom feed, but who’s counting) using the Nunjucks templating engine.

• GitHub.

Template Compatibility #

• Nunjucks

Installation #

Available on npm.

npm install @11ty/eleventy-plugin-rss --save-dev

Open up your Eleventy config file (probably .eleventy.js) and use addPlugin:

const pluginRss = require("@11ty/eleventy-plugin-rss");
module.exports = function(eleventyConfig) {
  eleventyConfig.addPlugin(pluginRss);
};

Supplies the following Nunjucks Filters #

• rssLastUpdatedDate: Gets the most recently updated content in the collection and retrieves the properly formatted Date for the top-level <updated> element.
• rssDate: format a Date to be used for individual <entry><updated> elements.
• absoluteUrl: converts a single URL (relative or absolute path) to a full absolute URL including protocol, domain, full path.
• htmlToAbsoluteUrls: transforms all of the URLs in a block of HTML with absoluteUrl above. Uses posthtml-urls with a[href], video[src], audio[src], source, img[src], [srcset] and a whole bunch more.

Sample Atom Feed template #

Copy and paste this template and modify the YAML metadata to match your feed’s needs. Make sure collections.posts matches the template collection you want to provide a feed for.
