Description

Converts currency codes to locale identifiers following format specified in IETF BCP 47 standard, comprised of a two-letter ISO 639-1 language code and ISO 3166-1 alpha-2 country code.

For currency codes with multiple locales/language codes, defaults have been selected.

Currency codes initially compiled using Frankfurter's https://api.frankfurter.app/currencies.

Additional currency code and locale ID additions are welcome; please see "Contributing" section below.

Usage

To use the currencyToLocale function in your project, import it as follows:

import currencyToLocale from 'currency-to-locale';

Function usage: currencyToLocale

currencyToLocale(currencyCode, languageCode)

The currencyToLocale function accepts two arguments:

• currencyCode (required): The 3-letter currency code (e.g. "USD", "EUR").
• languageCode (optional): The 2-letter language code (e.g. "en", "de").

It returns the corresponding locale identifier (e.g. "en-US", "de-DE").

Examples

// Example 1: Simple usage const locale = currencyToLocale('USD'); // returns 'en-US'

// Example 2: Currency code with multiple locales, returns locale based on language code provided const locale = currencyToLocale('EUR', 'fr'); // returns 'fr-FR'

// Example 3: Currency code with multiple locales, no language code provided (default locale returned) console.log("EUR with no language code:", currencyToLocale('EUR')); // returns 'de-DE'

// Example 4: Invalid or not-found currency code const locale = currencyToLocale('XYZ'); // returns 'Currency code not found.' const locale = currencyToLocale(1); // returns 'Please provide a valid currency code.'
