# ExtensionTargets


A [target](https://shopify.dev/docs/apps/app-extensions/configuration#targets) represents where your checkout UI extension will appear.

You register for [targets](https://shopify.dev/docs/api/checkout-ui-extensions/extension-targets-overview) in your [configuration file](https://shopify.dev/docs/api/checkout-ui-extensions/configuration), and you include a JavaScript function that will run at that location in checkout.

The API for each extension target is passed as an argument to your function. While all targets inherit the [`StandardApi`](https://shopify.dev/docs/api/checkout-ui-extensions/apis/standardapi), not all of them share the same properties and methods.

For example, the [`purchase.checkout.cart-line-item.render-after`](#typesofextensiontargets-propertydetail-purchasecheckoutcartlineitemrenderafter) target has access to the [`CheckoutApi`](https://shopify.dev/docs/api/checkout-ui-extensions/apis/checkoutapi) to modify a checkout, but the [`purchase.thank-you.cart-line-item.render-after`](#typesofextensiontargets-propertydetail-purchasethankyoucartlineitemrenderafter) target does not.
  

```jsx
import {
  reactExtension,
  Banner,
  useApi,
} from '@shopify/ui-extensions-react/checkout';

function Extension() {
  const {extension} = useApi();
  const {target} = extension;

  return (
    <Banner>
      This extension is rendering in the {target}
      extension target.
    </Banner>
  );
}

// You can export a single extension target per file

// ./Actions.jsx
export default reactExtension(
  'purchase.checkout.actions.render-before',
  () => <Extension />,
);

// ./Delivery.jsx
export default reactExtension(
  'purchase.checkout.delivery-address.render-before',
  () => <Extension />,
);

// ./ShippingOptions.jsx
export default reactExtension(
  'purchase.checkout.shipping-option-list.render-after',
  () => <Extension />,
);

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

```

```js
import {
  extension,
  Banner,
} from '@shopify/ui-extensions/checkout';

function renderExtension(root, {extension}) {
  root.appendChild(
    root.createComponent(
      Banner,
      {},
      `This extension is rendering in the ${extension.target} extension target.`,
    ),
  );
}

// You can export single a extension target per file

// ./Actions.jsx
export default extension(
  'purchase.checkout.actions.render-before',
  renderExtension,
);

// ./Delivery.jsx
export default extension(
  'purchase.checkout.delivery-address.render-before',
  renderExtension,
);

// ./ShippingOptions.jsx
export default extension(
  'purchase.checkout.shipping-option-list.render-after',
  renderExtension,
);

// ./Block.jsx
export default extension(
  'purchase.checkout.block.render',
  renderExtension,
);

```

## Types of extension targets

See a [visual representation](https://shopify.dev/docs/api/checkout-ui-extensions/extension-targets-overview#supported-locations) of each extension target.

### ExtensionTargets

A UI extension will register for one or more extension targets using `shopify.extend()`.
An extension target in a UI extension is a plain JavaScript function.
This function receives some API for interacting with the application,
and is expected to return a value in a specific shape.
The input arguments and the output type are different
for each extension target.

sets them using the [checkout editor](/apps/checkout/test-ui-extensions#test-the-extension-in-the-checkout-editor).

The [supported locations](https://shopify.dev/docs/api/checkout-ui-extensions/extension-targets-overview#supported-locations) for dynamic extension targets can be previewed during development

only supports translations for 'fr', then the `isoCode` for this
language is 'fr'. If your extension does not provide french
translations at all, this value is the default locale for your
