Localization support for POS UI extensions

Starting in POS 10.19, you can now localize your POS UI extensions for international merchants, staff, and customers. You can

  • Translate extension text: Define locale files with translation strings that automatically resolve based on customer and shop locales.
  • Format currencies and numbers: Use formatCurrency and formatNumber to display values in locale-appropriate formats.
  • Handle pluralization: Support complex plural rules across languages using the standard Intl.PluralRules specification.
