Link

A link is an interactive element in a user interface that allows users to navigate to another resource or location, typically on the web.

This component can be easily integrated into various frontend frameworks and customised through a set of properties.

Slots

Slot	Description
`default`	The default slot is used to pass text into the link component.
`icon`	Used to pass in an icon to the link component. The icon placement can be controlled via the `iconPlacement` prop and we recommend using pie-icons-webc for defining this icon, but this can also accept an SVG icon.

Using `pie-icons-webc` with the `pie-link` icon slot

We recommend using pie-icons-webc when using the icon slot. Here is an example of how you would do this:

<!--
  Note that pie-link and the icons that you want to use will need to be imported as components into your application.
  See the `pie-icons-webc` README for more info on importing these icons.
-->
<pie-link>
    <icon-plus-circle slot="icon"></icon-plus-circle>
    Search
</pie-link>

Events

This component does not emit any custom events. However, in order to use event listeners such as onclick to this component, you should pass the tag="button" prop to the component so it's treated like a native button element while maintaining the link look.

Examples

// import as module into a js file e.g. main.js
