Jekyll Feed plugin
A Jekyll plugin to generate an Atom (RSS-like) feed of your Jekyll posts
Installation
Add this line to your site's Gemfile:
gem 'jekyll-feed'
And then add this line to your site's _config.yml:
plugins:
- jekyll-feed
⚠️ If you are using Jekyll < 3.5.0 use the gems key instead of plugins.
Usage
The plugin will automatically generate an Atom feed at /feed.xml.
Optional configuration options
The plugin will automatically use any of the following configuration variables, if they are present in your site's _config.yml file.
titleorname- The title of the site, e.g., "My awesome site"description- A longer description of what your site is about, e.g., "Where I blog about Jekyll and other awesome things"url- The URL to your site, e.g.,http://example.com. If none is provided, the plugin will try to usesite.github.url.author- Global author information (see below)
Already have a feed path?
Do you already have an existing feed someplace other than /feed.xml, but are on a host like GitHub Pages that doesn't support machine-friendly redirects? If you simply swap out jekyll-feed for your existing template, your existing subscribers won't continue to get updates. Instead, you can specify a non-default path via your site's config.
feed:
path: atom.xml
To note, you shouldn't have to do this unless you already have a feed you're using, and you can't or wish not to redirect existing subscribers.
Optional front matter
The plugin will use the following post metadata, automatically generated by Jekyll, which you can override via a post's YAML front matter:
datetitleexcerptidcategorytags
Additionally, the plugin will use the following values, if present in a post's YAML front matter:
-
image- URL of an image that is representative of the post (can also be passed asimage.path) -
author- The author of the post, e.g., "Dr. Jekyll". If none is given, feed readers will look to the feed author as defined in_config.yml. Like the feed author, this can also be an object or a reference to an author in_data/authors.yml(see below).
Author information
TL;DR: In most cases, put author: [your name] in the document's front matter, for sites with multiple authors. If you need something more complicated, read on.
There are several ways to convey author-specific information. Author information is found in the following order of priority:
- An
authorobject, in the documents's front matter, e.g.:
author:
twitter: benbalter
- An
authorobject, in the site's_config.yml, e.g.:
author:
twitter: benbalter
site.data.authors[author], if an author is specified in the document's front matter, and a corresponding key exists insite.data.authors. E.g., you have the following in the document's front matter:
author: benbalter
And you have the following in _data/authors.yml:
benbalter:
picture: /img/benbalter.png
twitter: jekyllrb
potus:
picture: /img/potus.png
twitter: whitehouse
In the above example, the author benbalter's Twitter handle will be resolved to @jekyllrb. This allows you to centralize author information in a single _data/authors file for site with many authors that require more than just the author's username.
Pro-tip: If authors is present in the document's front matter as an array (and author is not), the plugin will use the first author listed.
- An author in the document's front matter (the simplest way), e.g.:
author: benbalter
- An author in the site's
_config.yml, e.g.:
author: benbalter
Meta tags
The plugin exposes a helper tag to expose the appropriate meta tags to support automated discovery of your feed. Simply place {% feed_meta %} someplace in your template's <head> section, to output the necessary metadata.
SmartyPants
The plugin uses Jekyll's smartify filter for processing the site title and post titles. This will translate plain ASCII punctuation into "smart" typographic punctuation. This will not render or strip any Markdown you may be using in a title.
Jekyll's smartify filter uses kramdown as a processor. Accordingly, if you do not want "smart" typographic punctuation, disabling them in kramdown in your _config.yml will disable them in your feed. For example:
kramdown:
smart_quotes: apos,apos,quot,quot
typographic_symbols: {hellip: ...}
Custom styling
Want to style what your feed looks like in the browser? Simply add an XSLT at /feed.xslt.xml and Jekyll Feed will link to the stylesheet.
Why Atom, and not RSS?
Great question. In short, Atom is a better format. Think of it like RSS 3.0. For more information, see this discussion on why we chose Atom over RSS 2.0.
Categories
Jekyll Feed can generate feeds for each category. Simply define which categories you'd like feeds for in your config:
feed:
categories:
- news
- updates
Collections
Jekyll Feed can generate feeds for collections other than the Posts collection. This works best for chronological collections (e.g., collections with dates in the filenames). Simply define which collections you'd like feeds for in your config:
feed:
collections:
- changes
By default, collection feeds will be outputted to /feed/<COLLECTION>.xml. If you'd like to customize the output path, specify a collection's custom path as follows:
feed:
collections:
changes:
path: "/changes.xml"
Finally, collections can also have category feeds which are outputted as /feed/<COLLECTION>/<CATEGORY>.xml. Specify categories like so:
feed:
collections:
changes:
path: "/changes.xml"
categories:
- news
- updates
