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.

Design Token CSS Custom Property dependency

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

For additional details in regards to using Auro Design Tokens with components, please see docs/TECH_DETAILS.md

CSS Custom Property fallbacks

CSS custom properties are not supported in older browsers. For this, fallback properties are pre-generated and included with the npm.

Any update to the Auro Design Tokens will be immediately reflected with browsers that support CSS custom properties, legacy browsers will require updated components with pre-generated fallback properties.

Define dependency in project component

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