Localization

The APIs for localizing your extension.

Anchor to standardapiStandardApi

The base API object provided to purchase, and customer-account.order-status extension targets.

Anchor to i18n i18n required: Utilities for translating content and formatting values according to the current localization of the checkout.

See localization examples for more information.
Anchor to localization localization required: Details about the location, language, and currency of the buyer. For utilities to easily format and translate content based on these details, you can use the i18n object instead.

I18n

formatNumber
Returns a localized number. This function behaves like the standard `Intl.NumberFormat()` with a style of `decimal` applied. It uses the buyer's locale by default.
```
(number: number | bigint, options?: { inExtensionLocale?: boolean; } & NumberFormatOptions) => string
```
formatCurrency
Returns a localized currency value. This function behaves like the standard `Intl.NumberFormat()` with a style of `currency` applied. It uses the buyer's locale by default.
```
(number: number | bigint, options?: { inExtensionLocale?: boolean; } & NumberFormatOptions) => string
```
formatDate
Returns a localized date value. This function behaves like the standard `Intl.DateTimeFormatOptions()` and uses the buyer's locale by default. Formatting options can be passed in as options.
```
(date: Date, options?: { inExtensionLocale?: boolean; } & DateTimeFormatOptions) => string
```
translate
Returns translated content in the buyer's locale, as supported by the extension. - `options.count` is a special numeric value used in pluralization. - The other option keys and values are treated as replacements for interpolation. - If the replacements are all primitives, then `translate()` returns a single string. - If replacements contain UI components, then `translate()` returns an array of elements.
```
I18nTranslate
```

I18nTranslate

This returns a translated string matching a key in a locale file.

Localization

currency
The currency that the buyer sees for money amounts in the checkout.
```
StatefulRemoteSubscribable<Currency>
```
timezone
The buyer’s time zone.
```
StatefulRemoteSubscribable<Timezone>
```
language
The language the buyer sees in the checkout.
```
StatefulRemoteSubscribable<Language>
```
extensionLanguage
This is the buyer's language, as supported by the extension. If the buyer's actual language is not supported by the extension, this is the fallback locale used for translations. 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).
```
StatefulRemoteSubscribable<Language>
```
country
The country context of the checkout. This value carries over from the context of the cart, where it was used to contextualize the storefront experience. It will update if the buyer changes the country of their shipping address. The value is undefined if unknown.
```
StatefulRemoteSubscribable<Country | undefined>
```
market
The [market](/docs/apps/markets) context of the checkout. This value carries over from the context of the cart, where it was used to contextualize the storefront experience. It will update if the buyer changes the country of their shipping address. The value is undefined if unknown.
```

Translating strings with pluralization

Description

You can use the `count` option to get a pluralized string based on the current locale. See [localizing UI extensions](/docs/apps/checkout/best-practices/localizing-ui-extensions) for more information.
