ISO-4217 Currencies

Simply a list of ISO-4217 currencies with name, code, symbol, & decimal rounding. Also, support for figuring out the currency based on ISO-3166-1 Alpha-2 country code.

Basic Usage

// include it
const lib = require('@blossomfinance/iso-4217-currencies');

// get metadata for a specific currency code
const usd = lib.currency('USD');
// {
//   "symbol": "$",
//   "name": "US Dollar",
//   "symbolNative": "$",
//   "decimalDigits": 2,
//   "rounding": 0,
//   "code": "USD",
//   "namePlural": "US dollars"
// }

// get currency metadata by country code
const eur = lib.currency('FR');
// {
//   "symbol": "€",
//   "name": "Euro",
//   "symbolNative": "€",
//   "decimalDigits": 2,
//   "rounding": 0,
//   "code": "EUR",
//   "namePlural": "euros"
// }

// get currency code for a country code
const code = lib.codeForCountry('CM');
// "XAF"

Why?

Most solutions available are super overkill, not distributed as packages (e.g. gist), and/or out of date.
