<auro-loader> is a HTML custom element 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 <auro-loader> 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 <auro-loader> supports currentColor, this allows for any color set on the parent element to influence the color of the loader.

The <auro-loader> 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 answer.

The use of any Auro custom element has a dependency on the Auro Design Tokens.

Defining the component dependency within each component that is using the <auro-loader> component.

import "@aurodesignsystem/auro-loader";
