Optics is a css package that provides base styles and components that can be integrated and customized in a variety of projects.

## Installation

### NPM

```sh
npm install @rolemodel/optics
```

### Yarn

```sh
yarn add @rolemodel/optics
```

### Importing with a compiler

You can add this import to the top of your root level `css` file.

```css
@import '@rolemodel/optics'; /* Using webpack to compile */
/* Or */
@import '@rolemodel/optics/dist/css/optics'; /* Using a different compiler */
/* Or */
@import '@rolemodel/optics/dist/css/optics.min.css'; /* If you want a single file with all the styles in it. */
```

### Importing without a compiler

To use Optics without compilation, use a CDN like [jsDelivr](https://www.jsdelivr.com/) or [unpkg](https://unpkg.com/).
Add a link in your HTML head or an `@import` to the top of your root level `css` file.

```html
<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/@rolemodel/optics@[desired version]/dist/css/optics.min.css"
/>
```

```css
@import 'https://cdn.jsdelivr.net/npm/@rolemodel/optics@[desired version]/dist/css/optics.min.css';
```

Note: You can use this method to use Optics with [CodePen](https://codepen.io/). In a CodePen project, go to `Settings > CSS`, find the section for adding external stylesheets, and add the CDN link as a resource.

## Documentation

We use [Storybook](https://storybook.js.org/docs/html/get-started/introduction) as a way to provide informative and interactive documentation.

It can be found here [Optics Documentation](https://docs.optics.rolemodel.design/)

### Token Documentation

We use the Storybook Design Token for showing design tokens in the documentation. This allows us to tag groups of tokens with a category and a presenter.

[Available Presenters](https://github.com/UX-and-I/storybook-design-token#available-presenters)

Add the following above a group to categorize the tokens.

```css
/**
* @tokens Basic Colors
* @presenter Color
*/
```

### Component Documentation

For instructions on how to create a new component, see [Process for Creating New Components](./NEW_COMPONENT.md)

Additional stories can be added using the following command, or copying an existing story.

```sh
npm run generate
```

The visual graphic found on the Selective Imports page in the documentation is generated from the `tools/generate-graph.dot` file. You can preview and export a newer svg version of the graphic by using the `tintinweb.graphviz-interactive-preview` VSCode extension.
