# Migrate SkeletonText to the Polaris skeleton paragraph component

The Polaris skeleton paragraph component displays a placeholder for text content while it loads. It replaces the previous [`SkeletonText`](https://shopify.dev/docs/api/checkout-ui-extensions/2025-07/ui-components/feedback-and-status-indicators/skeletontext) component and is available as [`<s-skeleton-paragraph>`](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/typography-and-content/skeleton-paragraph) in API versions 2025-10 and newer.

***

## Removed properties

### children

The previous `SkeletonText` component accepted any React node as children to size the placeholder. The Polaris skeleton paragraph doesn't render children. Use the [`content`](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/typography-and-content/skeleton-paragraph#properties-propertydetail-content) property instead, which accepts a `string` only. The `content` value is hidden and used only to size the skeleton.

## Migrating children to content

##### Latest (Preact)

```tsx
import '@shopify/ui-extensions/preact';
import {render} from 'preact';

export default function extension() {
  render(<Extension />, document.body);
}

function Extension() {
  return <s-skeleton-paragraph content="Order total" />;
}
```

##### Pre-Polaris (2025-07)

```tsx
import {
  reactExtension,
  SkeletonText,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return <SkeletonText>Order total</SkeletonText>;
}
```

### size

The Polaris skeleton paragraph component no longer supports `size`. The skeleton renders at a single default text size. If you need the skeleton to approximate a specific height, use `content` with placeholder text of representative length. The rendered height depends on the extension's width at render time.

### inline​Size

The Polaris skeleton paragraph component no longer supports `inlineSize`. The skeleton fills the full width of its container by default. If you previously used `inlineSize` to control the skeleton's width, use the `content` property with placeholder text to approximate the desired size.

## Migrating inlineSize

##### Latest (Preact)

```tsx
import '@shopify/ui-extensions/preact';
import {render} from 'preact';

export default function extension() {
  render(<Extension />, document.body);
}

function Extension() {
  return <s-skeleton-paragraph content="Placeholder" />;
}
```

##### Pre-Polaris (2025-07)

```tsx
import {
  reactExtension,
  SkeletonText,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return <SkeletonText inlineSize="small" />;
}
```

## Updated patterns

Before migrating your skeleton components, consider whether you still need them:

* **Automatic skeletons**: Shopify now automatically displays skeleton loading states when your app extension is loading. These provide a generic placeholder that roughly matches the size of your extension, so you might not need to manage skeletons manually.
* **Use loading states instead**: Consider leveraging disabled states of components or the `loading` prop on [`<s-button>`](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/actions/button) to indicate that something is loading, rather than replacing the entire block with skeletons.
* **Skeleton only the loading content**: Skeleton only the piece of content that's loading, not the entire UI.
