Madgex Design System

A work-in progress Design System for building a UI for Madgex products.

Usage

Available on NPM as @madgex/design-system.

npm install @madgex/design-system --save

NOTE: Right now you'll need to be authenticated on npm under the Madgex account.

Importing styles

You'll need to use the Madgex DS CSS file in your project (which you will find in @madgex/design-system/dist/css/index.css)

The design system is using CSS Custom Properties to apply the brand styling of each site so you will need to import the custom properties file found in S3 for each client property id as well.

if you want to use the default styling set in the design system, you can use the variables.css file found in dist/_tokens/css.

Working with hapi.js, vision and Nunjucks

If you're wanting to use the Madgex DS components from a hapi.js+vision+Nunjucks setup you'll need to include the Madgex DS in the Nunjucks pathing:

  engines: {
    njk: {
      compile: (src, options) => {
        const template = Nunjucks.compile(src, options.environment);
        return (context) => {
          return template.render(context);
        };
      },
      prepare: (options, next) => {
        options.compileOptions.environment = Nunjucks.configure(
          [
            Path.join(options.path),
            'node_modules/@madgex/design-system/',
            'node_modules/@madgex/design-system/src/',
            'node_modules/@madgex/design-system/src/components/',
          ],
          { watch: false }
        );
        return next();
      },
    },
  },

Then you should be able to use components as such:

{% extends "template.njk" %}  {# a base template is available in the DS #}

{% from "button/_macro.njk" import Button %} {# load the DS button component #}

{% block content %}

  <p>My new project homepage</p>

  {# Use the Madgex DS button! #}
  {{
    Button({
      text: 'Click me please!'
    })
  }}

{% endblock %}

Note you'll need the CSS for the component styles.

Releases

With every commit to master the build server attempts to create a new version using semantic-release and deploys to npm as @madgex/design-system.

Local Development with jobseekers-frontend

You can see your changes to the jobseekers-frontend in a local dev enviroment by using npm link.

cd [your local path]/madgex-design-system
npm link
cd [your local path]/jobseekers-frontend
npm link npm link @madgex/design-system

Building Tokens

We use Style Dictionary to build our Design System tokens.

createStyleDictionary(overridesObject:StyleDictionaryConfig?) : { styleDictionary:StyleDictionary, cleanTempFiles:Function }

createStyleDictionary(StyleDictionaryConfig) is exposed via @madgex/design-system/style-dictionary. This creates a new StyleDictionary Instance, preconfigured with our base tokens, and all platforms we want to build. See here for the base config we use.

You can supply overrides to createStyleDictionary which should be the same shape as Style Dictionary Configuration.

Typically you will only override buildPath on platforms (so the platform builds with the same transforms everywhere), and supply source token override file paths.

pre-configured platforms

A platform determines a certain type of output based on the tokens. When you create a new StyleDictionary Instance via createStyleDictionary, it comes with our pre-configured platforms :

• 'css-variables' : outputs variables.css to buildPath, CSS Variables
• 'json-variables' : outputs variables.json to buildPath, JSON version of CSS Variables, useful for rendering in Node e.g. display-image-render-api or template-renderer
• 'json-variables-flat' : outputs variables-flat.json to buildPath. similar to 'json-variables' but in a flat object structure

Example usage, overrides

In this example we override the buildPath of our pre-configured platforms. We also supply paths to override token files via source.

We then build only the platforms we want, and then call cleanTempFiles once we're done.

const path = require('node:path');
const { createStyleDictionary, cleanTempFiles } = require('@madgex/design-system/style-dictionary');

const { styleDictionary, cleanTempFiles } = await createStyleDictionary({
  platforms: {
    'css-variables': {
      buildPath: `${path.resolve(__dirname, '../yes-here')}/`,
    },
    'json-variables': {
      buildPath: `${path.resolve(__dirname, '../yes-here')}/`,
    },
  },
  source: [path.resolve(__dirname, '../brand.json')],
});

await styleDictionary.buildPlatform('css-variables');
await styleDictionary.buildPlatform('json-variables');

await cleanTempFiles();
