Icon Button

An icon button uses icons as its primary visual element, representing actions or functions in a compact and visually appealing way.

Overview

pie-icon-button is a Web Component built using Lit. It offers a simple and accessible icon button component for web applications.

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

Installation

To install pie-icon-button in your application, run the following on your command line:

npm i @justeattakeaway/pie-webc

yarn add @justeattakeaway/pie-webc

Importing Icons

We recommend using the pie-icons-webc package alongside pie-icon-button. This package contains all of the PIE icons as importable web components and are built to work alongside our other PIE components.

pie-icon-button provides a slot into which you can pass your chosen icon, and it will automatically size it to the correct dimensions depending on the size of the pie-icon-button component.

Importing an icon with `pie-icons-webc`

To import an icon using pie-icons-webc, you should import the icon that you would like to use alongside the pie-icon-button component:

import '@justeattakeaway/pie-webc/components/icon-button.js';
import '@justeattakeaway/pie-icons-webc/dist/IconClose.js';

Then, in your markup, you would implement the component like this:

<pie-icon-button>
  <icon-close></icon-close>
</pie-icon-button>
