Install dependencies

npm install

Run storybook locally

To run storybook locally as a development environment use the following command:

npm run storybook

Build components library and styling

To build the components library for publishing run the following:

npm run build

Run tests

npm run test

You can also run the tests in watch mode by running:

npm run test:watch

Run type-checking

Running storybook locally doesn't type-check. You can run the type-checking with the following command:

npm run check-types

You can also run the type-checking in watch mode by running:

npm run check-types:watch

Create a new component

There's a template for new components. You can create the base structure for a new component just by running:

./make_component.sh [your component name here]

For example: ./make_component.sh Input.

Build details

We use babel for the build process using the react-app preset as well as the typescript compiler for the declarations output.

However take note that storybook uses its own webpack and babel configurations, even though they match the react-app preset, any other configurations might need adding in both .storybook/webpack.config.js and .babelrc

If using VSCode

You might want these extensions for linting, code style, MDX support, and styled-components highlighting:

VSCode by default uses its own version of typescript for typechecking instead of the workspace's. The ESLint Visual Studio Code extension currently doesn't have TypeScript support enabled by default. You can also run Prettier to format your code on save.

For these reasons here's an example settings file for vscode. Add the following to your project's Visual Studio Code settings file, located at .vscode/settings.json (you can create this file if it doesn't already exist):

  "typescript.tsdk": "node_modules/typescript/lib",
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "eslint.validate": ["javascript", "javascriptreact", "typescript", "typescriptreact", "markdown", "mdx"],
  "[javascript]": {
    "editor.formatOnSave": true
  "[javascriptreact]": {
    "editor.formatOnSave": true
  "[typescript]": {
    "editor.formatOnSave": true
  "[typescriptreact]": {
    "editor.formatOnSave": true
  "[markdown]": {
    "editor.formatOnSave": true
  "[mdx]": {
    "editor.formatOnSave": true
