RSS Feed in a 11ty site
Published on in RSS, 11ty & Web Development.

Dave Rupert is right. Really Simple Syndication or RSS is a great way for people to digest their favorite blog articles with a RSS reader of their choice not be bombarded with ads, click-bait, and spam. So why not do your readers a favor and add it to your 11ty blog?

Install package #

Start in your 11ty project folder and install this package.

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

Include in your 11ty configuration #

In the .eleventy.js file, require the plugin and include it in the module.exports function with any other plugins you may have.

const pluginRss = require("@11ty/eleventy-plugin-rss");

module.exports = function(eleventyConfig) {

Add to feed metadata #

In the _data/metadata.json file, add the unique metadata for the feed.

"feed": {
"subtitle": "Tech posts to educate, elevate, but mostly entertain.",
"filename": "feed.xml",
"path": "/feed/feed.xml",
"url": "",
"id": ""

Create a RSS feed #

From your top-level of your 11ty project folder, create this template file.

touch src/feed.xml

Atom has several advantages over RSS: less restrictive licensing, IANA-registered MIME type, XML namespace, URI support, RELAX NG support. [1] Knowing this, we will copy and paste the Atom format to produce our feed template. Other formats are available such as RSS and JSON. [2]

# Metadata comes from _data/metadata.json
permalink: "{{ metadata.feed.path }}"
eleventyExcludeFromCollections: true
<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="">
<title>{{ metadata.title }}</title>
<subtitle>{{ metadata.feed.subtitle }}</subtitle>
<link href="{{ metadata.feed.url }}" rel="self"/>
<link href="{{ metadata.url }}"/>
<updated>{{ collections.posts | getNewestCollectionItemDate | dateToRfc3339 }}</updated>
<id>{{ metadata.url }}</id>
<name>{{ }}</name>
<email>{{ }}</email>
{%- for post in collections.posts | reverse %}
{% set absolutePostUrl %}{{ post.url | url | absoluteUrl(metadata.url) }}{% endset %}
<title>{{ }}</title>
<link href="{{ absolutePostUrl }}"/>
<updated>{{ | dateToRfc3339 }}</updated>
<id>{{ absolutePostUrl }}</id>
<content type="html">{{ post.templateContent | htmlToAbsoluteUrls(absolutePostUrl) }}</content>
{%- endfor %}

Important: This code assumes you save your date frontmatter in UTC format, not your local timezone.

That's it. You now have a Atom v1.0 feed on your 11ty website when you serve or build the project.
