Installation

To install any of our web components in your application, we would suggest following the getting started guide to set up your project.

Ideally, you should install the component using the @justeattakeaway/pie-webc package, which includes all of the components. Or you can install the individual component package.

Note: If you want to change the height or width of the animation, you should pass a class that sets the desired values as the animation will scale to its container size automatically.

Slots

Events

This component does not emit any custom events. In order to add event listening to this component, you can treat it like a native HTML element in your application.

Usage Examples

For HTML:

// import as module into a js file e.g. main.js
import '@justeattakeaway/pie-webc/components/pie-lottie-player.js';

<!-- pass js file into <script> tag -->
<pie-lottie-player animationSrc="./animation-file.json"></pie-lottie-player>
<script type="module" src="/main.js"></script>

For Native JS Applications, Vue, Angular, Svelte, etc.:

// Vue templates (using Nuxt 3)
import '@justeattakeaway/pie-webc/components/pie-lottie-player.js';

<pie-lottie-player animationSrc="./animation-file.json"></pie-lottie-player>

For React Applications:

import { PieLottiePlayer } from '@justeattakeaway/pie-webc/react/lottie-player.js';

<PieLottiePlayer animationSrc="./animation-file.json"></PieLottiePlayer>

Accessibility

Currently the component is always hidden from screen readers because animations should only be decorative and supplementary. Any important meaning and context should be presented alongside the animation as text.

For the users with the "Reduce motion" setting enabled, the animation will be paused on the first frame.
