# Loader

`` is a [HTML custom element](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_custom_elements) for the purpose of illustrating animated loaders.

Things take time. Sometimes we just need to take a second for some data to show up. For this Auro supports the `` custom element. This powerful element supports multiple modes for use, `ringworm`, `orbit`, `pulse`, and `laser`.

And each of these modes support five size settings, `default`, `sm`, `md`, `lg`, and `xl`.

For color support `` supports `currentColor`, this allows for any color set on the parent element to influence the color of the loader.

The `` custom element also supports three pre-defined color modes, `onlight`, `ondark` and `white`.

Installing as a direct, dev or peer dependency is up to the user installing the package. If you are unsure as to what type of dependency you should use, consider reading this [stack overflow](https://stackoverflow.com/questions/18875674/whats-the-difference-between-dependencies-devdependencies-and-peerdependencies) answer.

### Design Token CSS Custom Property dependency

The use of any Auro custom element has a dependency on the [Auro Design Tokens](https://auro.alaskaair.com/getting-started/developers/design-tokens).

### Define dependency in project component

Defining the component dependency within each component that is using the `` component.

```js
import "@aurodesignsystem/auro-loader";
```

**Reference component in HTML**

```html

```

## Install bundled assets from CDN

In cases where the project is not able to process JS assets, there are pre-processed assets available for use. See -- `auro-loader__bundled.js` for modern browsers. Legacy browsers such as IE11 are no longer supported.

**WARNING!** When installing into your application environment, DO NOT use `@latest` for the requested version. Risks include unknown MAJOR version releases and instant adoption of any new features and possible bugs without developer knowledge. The `@latest` wildcard should NEVER be used for production customer-facing applications. You have been warned.

### Bundle example code

```html

```

## auro-loader use cases

The `` element should be used in situations where developers may need to illustrate a wait time for their users.

### Testing

Automated tests are required for every Auro component. See `.\test\auro-loader.test.js` for the tests for this component. Run `npm test` to run the tests and check code coverage. Tests must pass and meet a certain coverage threshold to commit. See [the testing documentation](https://auro.alaskaair.com/support/tests) for more details.

### Bundled assets
