# ExtensionTargets


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

You register for [targets](/docs/api/checkout-ui-extensions/extension-targets-overview) in your [configuration file](/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`](/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`](/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.

## Types of extension targets
See a [visual representation](/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.

### formatCurrency

value: `(number: number | bigint, options?: { inExtensionLocale?: boolean; } & NumberFormatOptions) => string`

For example, if the buyer's language is 'fr-CA' but your extension
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
extension (that is, the one matching your .default.json file).

### country
