11ty-design-system

A Simple Design System generator for 11ty, with support for Design Token itemizing and WebC components.

Folders

All design tokens can be found in src/_data/designTokens. This includes all baseline fonts, colors, sizes, and spacing in a format generated via https://utopia.fyi/
All components and their documentation should be in folders under src/_includes/components. As long as there's an accompanying *.config.js file it'll get picked up and auto generated in the design system.
All design system layouts can be found in src/_includes/layouts and are prefixed with ds-.
To document atomic elements of your design system that aren't components, you can add pages under src/design-system/ just as you would any standard Eleventy page. There are several already started for you under Atoms that itemize block, form, inline, and preformatted HTML tags.

There are examples of just documentation in the Card and Quote folders
There are examples of WebC components and their documentation under _Compositions/sidebar and _Compositions/stack
For components that you do not want to document, leave out the *.config.js file. Utils/ds-menu.webc is one existing example of this.
The design tokens are automatically documented by the src/design-system/Atoms/tokens.njk page. This will source the tokens directly from the data files so it updates as the tokens themselves are updated.

This project uses Tailwind to auto-generate the CSS based on the design tokens (credit to Andy Bell and buildexcellentwebsit.es for this.)
WebC Components are auto-imported as long as they're under the src/_includes/components folder. Styles and JS are compiled at build time so using these web components should be seamless from there.

This project is an amalgamation of the following, without whom this would not exist:

Eleventy 2.0 and WebC has me very excited about the future of leveraging the modular nature of web components outside of a larger JavaScript framework. I wouldn't have started this if it weren't for all this excellent work
Fluid type, space, and grid systems generated via https://utopia.fyi/
Design Tokens based on buildexcellentwebsit.es
CSS structure is based on Cube CSS
Self-documenting design system inspired by this one from Trys Mudford, and furter explained in this blog post.
Some of the base styling are based on SmolCSS and Every Layout

I'd ideally like this to be an Eleventy plugin that can be installed, but as far as I can tell there's not a way to do so until Virtual Templates are made available.
The Design System sidebar menu is limited to three levels currently because WebC doesn't yet support recursion, once this issue is resolved it'll be much easier to support additional folders in the components directory.
I had originally tried using WebC components for the full page (src/design-system/components-full-pages.njk) and component page (src/design-system/components-pages.njk) templates but there's an issue with WebC and dynamic permalinks. I've created an issue regarding this.
Considering adding some more baseline WebC components to this project as well, especially those found in Tugboat
