Electron Documentation

jlordjlord RSS Feed

This week we’ve given Electron’s documentation a home on electron.atom.io. You can visit /docs/latest for the latest set of docs. We’ll keep versions of older docs, too, so you’re able to visit /docs/vX.XX.X for the docs that correlate to the version you’re using.

You can visit /docs to see what versions are available or /docs/all to see the latest version of docs all on one page (nice for cmd + f searches).

If you’d like to contribute to the docs content, you can do so in the Electron repository, where the docs are fetched from. We fetch them for each minor release and add them to the Electron site repository, which is made with Jekyll.

If you’re interested in learning more about how we pull the docs from one repository to another continue reading below. Otherwise, enjoy the docs!

The Technical Bits

We’re preserving the documentation within the Electron core repository as is. This means that electron/electron will always have the latest version of the docs. When new versions of Electron are released, we duplicate them over on the Electron website repository, electron/electron.atom.io.


To fetch the docs we run a script with a command line interface of script/docs vX.XX.X with or without the --latest option (depending on if the version you’re importing is the latest version). Our script for fetching docs uses a few interesting Node modules:

Tests help us know that all the bits and pieces landed as expected.


The Electron website is a Jekyll site and we make use of the Collections feature for the docs with a structure like this:

└── _docs
    ├── latest
    ├── v0.27.0
    ├── v0.26.0
    ├── so on
    └── so forth

Front matter

For Jekyll to render each page it needs at least empty front matter. We’re going to make use of front matter on all of our pages so while we’re streaming out the /docs directory we check to see if a file is the README.md file (in which case it receives one front matter configuration) or if it is any other file with a markdown extension (in which case it receives slightly different front matter).

Each page receives this set of front matter variables:

version: v0.27.0
category: Tutorial
title: 'Quick Start'
source_url: 'https://github.com/electron/electron/blob/master/docs/tutorial/quick-start.md'

The README.md gets an additional permalink so that has a URL has a common root of index.html rather than an awkward /readme/.

permalink: /docs/v0.27.0/index.html

Config and Redirects

In the site’s _config.yml file a variable latest_version is set every time the --latest flag is used when fetching docs. We also add a list of all the versions that have been added to the site as well as the permalink we’d like for the entire docs collection.

latest_version: v0.27.0
    - v0.27.0
    docs: {output: true, permalink: '/docs/:path/'}

The file latest.md in our site root is empty except for this front matter which allows users to see the index (aka README) of the latest version of docs by visiting this URL, electron.atom.io/docs/latest, rather than using the latest version number specifically (though you can do that, too).

permalink: /docs/latest/
redirect_to: /docs/1.4.14


In the docs.html layout template we use conditionals to either show or hide information in the header and breadcrumb.

{% if page.category != 'ignore' %}
<h6 class='docs-breadcrumb'>{{ page.version }} / {{ page.category }}
  {% if page.title != 'README' %} / {{ page.title }} {% endif %}</h6>
{% endif %}

To create a page showing the versions that are available we just loop through the list in our config on a file, versions.md, in the site’s root. Also we give this page a permalink: /docs/

{% for version in site.available_versions %}
- [{{ version }}](/docs/{{ version }})
{% endfor %}
