SkeletonText

Examples

• Basic SkeletonText

  React

  import {
    reactExtension,
    SkeletonText,
  } from '@shopify/ui-extensions-react/checkout';
  
  export default reactExtension(
    'purchase.checkout.block.render',
    () => <Extension />,
  );
  
  function Extension() {
    return <SkeletonText />;
  }
  

  JS

  import {extension, SkeletonText} from '@shopify/ui-extensions/checkout';
  
  export default extension('purchase.checkout.block.render', (root) => {
    const skeletonText = root.createComponent(SkeletonText);
  
    root.appendChild(skeletonText);
  });
  

• Using skeleton loaders to prevent layout shifts on content load.

  Description

  When adding content to a layout, incorporate a skeleton loader that renders the approximate size and position of the content during loading. This will provide a seamless transition from skeleton loaders to the content, and prevent any layout shift when the resulting content loads.

  React
