# Localization

Web components are aware of the selected locale (e.g.: en-us, fr-fr, ...) and selected currency (e.g. USD, EUR...) that is selected in the storefront. 

The following aspects of localization are handled:

## Text direction

The CSS of the web components work for both left-to-right and right-to-left locales (e.g., European languages are left-to-right, Arabic right-to-left).

## Language

The app assumes that the selected locale is exposed using a global variable declared on the window object named `window.Shopify.locale`.

Text labels for supported languages can be overridden in the app. Support for other languages can also be added in the app.

{% hint style="info" %}
Multi-language capabilities are not available on all plans.
{% endhint %}

## Currency

Prices and amounts are formatted using the currency formatting that is configured in the app.

The app assumes that the selected currency is exposed using a global variable declared on the window object named `window.Shopify.currency`.
