About

A baseline architecture for creating and distributing a React component library.

Development

Install Dependencies

Install root project and Storybook dependencies:

npm install
npm run sb:install

Start Storybook

npm run sb

Navigate to http://localhost:4000 to view the component documentation.

Themes

Themes can be defined in library/styles/themes/[name].css. By default, Storybook uses library/styles/themes/index.css. This can be changed by altering the defaultTheme in postcss.config.js.

Distribution

This process is automatically run on npm publish via the prepublishOnly lifecycle hook.

npm run dist

Creates the following directory:

└── dist
    ├── cjs
    ├── esm
    ├── umd
    └── styles

Each module format directory contains an index.js. The esm and cjs directories also contain individual exports for each component.

The styles directory contains an index.css and any other [theme].css files.

Consuming as a Package

npm install design-system-starter

Using import:

import { Example } from 'design-system-starter';

Using require:

const { Example } = require( 'design-system-starter' );

The main entry point (in package.json) defaults to UMD (Universal Module Definition).

Each component is also exposed in both ECMAScript Module and CommonJS formats.

CSS

The CSS for all components is located at node_modules/design-system-starter/dist/styles/index.css and can be added using any approach supported by your application.

CJS

Destructured from full library of components:

const { Example } = require( 'design-system-starter/dist/cjs' );

Individual component:

const Example = require( 'design-system-starter/dist/cjs/example' );

ESM

Destructured from full library of components:

import { Example } from 'design-system-starter/dist/esm';

Individual component:

import Example from 'design-system-starter/dist/esm/example';

UMD Browser Global

The UMD (Universal Module Definition) format enables access to the components in both Node and the browser.

Components are exposed via the DS global variable in the browser.

<script src="path/to/dist/umd/index.js"></script>
<script>
  ReactDOM.render(
    <DS.Example/>,
    document.getElementById('root')
  );
</script>
