Pattern Lab version of The Hatter style-guide for MidCamp.org

Getting Started

Prerequisite: NodeJS - https://nodejs.org/en/

Install dependencies:

npm install

Run Pattern Lab in watch mode (watches for changes in patterns and scss):

npm start

Pattern Lab can then be viewed at http://127.0.0.1:3000

Structure

The bulk of the code lives in the appropriately named source directory. Within sourcethe _patterns directory contains the elements, components, and templates that make up this style guide.

source/scss contains the main scss file for the project (styles.scss) and any scss partials not directly related to patterns in the system. Long term, most of the remaining partials in source/scss/components should be moved alongside a related pattern in _patterns

Image and svg assets are contained in source/imgs and source/svg respectively.

Compiled assets land in the dist directory. At the moment this is ignored by version control. Depending on the build process for the theme that uses this as a dependency, we may want to change that.

Editing patterns

If for example we wanted to make adjustments to the news teaser component, we'd edit the source files in source/_patterns/01-components/news-teaser

_c-news-teaser.scss is a sass partial containing styles related to this component. The leading c- is namespacing to indicate that is a component.

c-news-teaser.md is a markdown file containing documentation for the component.

c-news-teaser.twig contains markup for the component.

Creating new patterns

To create a new pattern, create a new subdirectory in the appropriate top level pattern directory (01-components for example.)

A pattern must at least have a pattern-name.twig file containing markup for the pattern.

The following optional files can also be included: pattern-name.md - Documentation for the pattern _pattern-name.scss - sass partial for the pattern (it should automatically be detected when compining the main sass file.) pattern-name.(yml/json) - Data for the pattern

• npm run watch - run Webpack in watch mode
• npm run dist - build pattern library assets in producion mode

Open Questions

• Should CSS be committed to repo?
• Do we want to compile js as part of build process?
• Strategy for including this pattern library as a dependency of the midcamp theme.

Todo

• Deploy static Pattern Library export to Github pages.
• Move more components into _patterns
• Configure JS bundling so that it exists if we want to use it.

Patches

• Patched the now abandoned Singularity GS to prevent warnings from node sass as outlined here: at-import/Singularity#248
