Pirati UI kit

This repository holds UI styleguide for Czech Pirate Party websites.

It is built upon:

• Patternlab is an awesome tool for developing design systems
• Tailwind CSS is a brilliant utility-first CSS framework built on top of PostCSS

Getting Started

These instructions are for getting the project running off a local development environment:

• Install any system requirements on your dev environment
• Use NPM to install project dependencies and build the project

System Requirements

• Node.js (v12.14.1 LTS or later recommended)

Install and Run

It's Javascript all the way down so once you have the the system requirements you can run the following commands:

npm i
npm run develop

The npm command will install project dependencies and the npm run develop command builds the project, sets up a local server for the Patternlab UI and watches relevant template files to rebuild on any changes.

Build

The build command compiles the styleguide CSS and the Patternlab output but it doesn't create a server for the styleguide website. To build, run:

npm run build

Configuring Tailwind

Tailwind CSS comes with default configuration that sets up things like scales for typography, spacing and colours but these defaults and additional configuration can be made by editing the tailwind.config.js file in the project root.

Note: if changes to configuration or custom components aren't appearing you may need to rebuild/restart Patternlab. Use control + c to stop Gulp and npm run develop to rebuild and start the dev server for Patternlab.

Find out more at the Tailwind website.

Extending Tailwind with PostCSS modules

PostCSS is a tool for transforming CSS using Javascript and there's already a huge number of modules you can use to do all kinds of things. This starter kit already has the Purge PostCSS module added but you can add additional modules in the Gulp configuration.

For example:

// at root, in gulpfile.js
gulp.task('tailwind-postcss', function () {
  return gulp.src('./source/css/style.css')
    .pipe(postcss([
      // Add more modules here and
      require('postcss-import'),
      require('postcss-nested'),
      require('postcss-preset-env'),
      tailwindcss('./tailwind.config.js'),
      require('autoprefixer'),
      assets({
        basePath: 'source/',
        loadPaths: ['images/']
      }),
      require('postcss-clean')
    ]))
    .pipe(rename('style.pkgd.css'))
    .pipe(gulp.dest('./source/dist'));
});

gulp.task('tailwind-postcss:production', function(){
  return gulp.src('./source/css/style.css')
    .pipe(postcss([
      // Here same time
      require('postcss-import'),
      require('postcss-nested'),
      require('postcss-preset-env'),
      tailwindcss('./tailwind.config.js'),
      require('autoprefixer'),
      assets({
        basePath: 'source/',
        loadPaths: ['images/']
      }),
      require('postcss-clean'),
      postcssPurgecss
    ]))
    .pipe(rename('style.pkgd.css'))
    .pipe(gulp.dest('./source/dist'));
});

Note: PurgeCSS should run only for the production build because added tailwind selector will not be applied when browser is reloaded.

Configuring Patternlab

The project has Patternlab setup to use the Tailwind CSS output but you can add additional CSS or JS to the Patternlab styleguide as you need.

The existing CSS output file (sytle.css) is linked in the _00-head.mustache template file located at /sources/_meta.

You can add additional Javascript files to /sources/js and then link them into the header and footer templates located at /sources/_meta.

Find out more at the Patternlab website.

Background

The version of Patternlab we're using is running in NodeJS with Gulp as a taskrunner, Tailwind CSS is a PostCSS project so it is part of the Javascript eco-system too.
