Component Structure

.
└── source
    └── ComponentA
        ├── __snapshots__
        │   └── test.tsx.snap
        ├── index.tsx
        ├── stories.tsx
        ├── styles.css
        └── test.tsx
    └── ComponentB
        └── ...
    └── ComponentC
        └── ...

The component and everything to do with it are co-located in the source/ComponentA/ folder:

• index component file (and any additional component files)
• stories
• CSS
• tests

Importing

JS

Component JavaScript can be imported in a few different ways:

// importing from the index file
import { Circle } from 'mylib'

// import directly from the esm build
import Circle from 'mylib/dist/esm/Circle'

// import directly from the commonjs build
import Circle from 'mylib/dist/cjs/Circle'

// import directly from the umd build
import Circle from 'mylib/dist/umd/Circle'

CSS

Component CSS can be imported like this:

import 'mylib/dist/css/Circle/styles.css'

If you wish to import all components' CSS:

import 'mylib/dist/css/styles.css'

A Note About Exports

All components are exported in source/index.ts, and their inclusion here is what allows them to get included in the build output in dist.

// source/index.ts

export { default as Circle } from './Circle'
export { default as Rectangle } from './Rectangle'

Developing

You can look inside package.json to see all the scripts, but here are some helpful ones:

• Build all the things: $ npm run build
• Run the Storybook examples: $ npm start
• Run the tests: $ npm test
• Run the linter: $ npm run lint
