Compound Web

React implementation of Compound – Element's design system – See full documentation on https://compound.element.io and the Figma component library

Development

Command	Runs
yarn dev	Runs a local Storybook server
yarn lint	Lints all components
yarn gen:component $name	Bootstraps a new component

Testing

Command	Runs
yarn test	Runs unit tests
yarn e2e:docker	Runs end-to-end tests
yarn e2e:docker -u	Updates end-to-end test snapshots

All components are expected to come with comprehensive unit tests and visual tests. We use Playwright to run visual tests on every story present in Storybook, so story coverage is really important! It helps us validate component implementations against the designs and prevents visual regressions at the same time.

We recommend running the end-to-end tests via Docker as shown above to get consistent text rendering for screenshots.

Linking

If you want to work on Compound Web as a linked package within a larger React application, TypeScript might complain about there being multiple copies of @types/react in the tree. You can work around this by linking Compound Web's copy of @types/react to your application's copy:

$ cd my-application/node_modules/@types/react
$ yarn link
$ cd ../../../../compound-web
$ yarn link @types/react
