Static website for ceph.io. Built with Eleventy.
- Node.js v14.2.0 (includes npm v6.14.4)
Earlier versions of Node and npm will also work, but we recommend using these versions for consistency between builds and environments.
We use nvm to manage Node versions when working locally, and run the nvm use command before getting started in development.
$ npm install
Install all dependencies, as specified in package.json. The majority of these are devDependencies, which cover any packages used during development and build processes. Packages installed as dependencies are those intended to be shipped to end-users as part of the built product.
Eleventy is a simple static site generator built on Node.js. It's a fast and flexible alternative to Jekyll and Hugo, and sits nicely alongside modern web projects. Visit the Eleventy docs for detailed feature information and example projects.
$ npm start
Serve the site in development mode at localhost:8080, watching for changes. The site will automatically rebuild and refresh when files change.
Under the hood, this is running Eleventy with the --serve flag. For more information, see Command line usage docs.
$ npm run build
Build the site for production. This will build, optimise and generate a complete build package for deployment on any static web host.
Files are output to the dist directory, which is excluded from version control.
npm run build action is intended for the build server and production environment only. Building the site isn't necessary during development. In the future when there are multiple languages running a build will also initiate scripts/prebuild.js, which is responsible for duplicating any missing pages from the default language site (en) to all supporting language sites (as determined by the _data/locales). This additional script ensures that we have content parity across all sites in production, falling back to English where content is not available. The files generated across the supporting language site directories should not be committed to version control.
$ npm run debug
Run a build with a verbose log of information on files and data being processed. This can be helpful for troubleshooting issues during development or when deploying via CI.
More information is available in the Debugging docs.

At the beginning of all pages, there's a block of data wrapped with ---. This is called frontmatter and it will follow a specific schema relative to the page you are on.
The frontmatter data is written in YAML format using key: value pairs.
Pages can contain a mix of Markdown and HTML. This means we can intersperse basic content formatting with more bespoke HTML elements in the same file.
# Page title
A paragraph of text, Markdown style.
- Markdown list items
- Lists are great
<article class="bespoke">
<h2>Stick to HTML</h2>
</article>
The caveat here is to ensure that there is always a clear break between Markdown and HTML elements. Mixing and matching the two in a single content block will not work.

To learn more about what's possible in Markdown, see Markdown Guide.
Linking to pages throughout the site works in the same way as linking to pages in standard HTML sites.
We'll most likely be using Markdown's link syntax to link to pages. The links we choose can be relative or absolute.
Let's use a blog-posts page (/blog/yyyy/blog-post) as an example. If we want to link to another blog post page it can be done in two ways:
[Relative link to blog post](../blog-post/)
[Root relative link to blog post](/blog/yyyy/blog-post/)If we need to link to another section/page within the site we can use either method shown above. The ../ prefix can be used to traverse further up the site tree:
[Relative link to my parent](../)
[Relative link to my grandparent](../../)
[Relative link to a sibling of mine](../sibling-page/)Note: these don't need filename .md/.html extensions.
Only use absolute URLs for links out of the site:
[Absolute link to Ceph.io](https://ceph.io/)We can interpolate these dynamic values throughout the Markdown. For example, we can save ourselves repeating the page's title property for our page title heading by using the {{ }} syntax:
---
title: Don't repeat yourself
---
# Don't repeat yourselfbecomes:
---
title: Don't repeat yourself
---
# {{ title }}Shortcodes are reusable code snippets that allow us to sweep away complicated markup into a nice, easy user interface.
<iframe
width="560"
height="315"
src="https://www.youtube.com/embed/vQF17UBU4RE"
title="Ceph Tech Talk: Karan Singh - Scale Testing Ceph with 10Billion+ Objects 2020-10-01"
frameborder="0"
allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
allowfullscreen
></iframe>
We can capture this markup in a shortcode so we don't need to repeat it everytime we want to embed a YouTube video. It accepts two values, the id and the title of the video, and uses the following syntax:
{% YouTube 'vQF17UBU4RE', 'Ceph Tech Talk: Karan Singh - Scale Testing Ceph with 10Billion+ Objects 2020-10-01' %}
We call shortcodes by name with the Nunjucks block syntax: {% YouTube %}. The first argument we pass is the id of the video (e.g. 'vQF17UBU4RE'). The second (optional) argument will set the title attribute of the iframe embed (e.g. 'Ceph Tech Talk: Karan Singh - Scale Testing Ceph with 10Billion+ Objects 2020-10-01').
Note: Shortcode arguments are type-/space-sensitive, so should should include surrounding ' quote marks.
We now have a single source of truth for the YouTube embed code making it easy to maintain and easy to reuse with a simple, clean interface.
