## CORE React ![npm](https://img.shields.io/npm/v/@procore/core-react.svg) ![npm](https://img.shields.io/npm/dt/@procore/core-react.svg)

A set of React components implementing the design system spec.

## Requirements

Node 16+
YARN 4+

## Usage

### Install

Install `@procore/core-react` from [NPM](https://www.npmjs.com/package/@procore/core-react).

```sh
yarn add @procore/core-react
```

Install the peer dependencies.

```sh
yarn add styled-components @procore/globalization-toolkit react-beautiful-dnd react react-dom
```

Install the optional peer dependencies if necessary.

```sh
yarn add formik
```

### Styles

Core React's styled components handle all style inclusion except for two cases:

1. Border box and all elements

```css
*,
::after,
::before {
  box-sizing: border-box;
}
```

2. Font Family

```css
font-family: Inter, 'Noto Sans JP', 'Noto Sans KR', 'Noto Sans SC',
  'Noto Sans TC', Arial, sans-serif;
```

### Imports

Named imports support tree shaking and types.

```tsx
import { Button, ButtonProps } from '@procore/core-react'
import { Cog } from '@procore/core-icons'

export function ButtonCustom(props: ButtonProps) {
  return <Button {...props} icon={<Cog />} />
}
```

## Developing

To get started, type the following from the project root directory:

```sh
yarn
```

All commands below will be ran in the package directory:

```sh
cd packages/core-react
```

We use Storybook to develop. Stories are broken into two categories, Demos for interactions and Coverage for displaying variants.

```sh
yarn storybook
```

## Testing

Testing currently consists of Jest snapshots and React Testing Library tests.

```sh
yarn test
```

Additional testing includes Visual Regression Testing (VRT) that is ran in CI, which compares pixel snapshots of Storybook Coverage stories.

## Building

```
yarn build
```
