// Support french & english languages.
countries.registerLocale(require("@notarise-gov-sg/i18n-iso-countries/langs/en.json"));
countries.registerLocale(require("@notarise-gov-sg/i18n-iso-countries/langs/fr.json"));

Code to Country

Get the name of a country by its ISO 3166-1 Alpha-2, Alpha-3 or Numeric code

var countries = require("@notarise-gov-sg/i18n-iso-countries");
// in a browser environment: countries.registerLocale(require("@notarise-gov-sg/i18n-iso-countries/langs/en.json"));
console.log("US (Alpha-2) => " + countries.getName("US", "en", {select: "official"})); // United States of America
console.log("US (Alpha-2) => " + countries.getName("US", "de", {select: "official"})); // Vereinigte Staaten von Amerika
console.log("USA (Alpha-3) => " + countries.getName("USA", "en", {select: "official"})); // United States of America
console.log("USA (Numeric) => " + countries.getName("840", "en", {select: "official"})); // United States of America

Get all names by their ISO 3166-1 Alpha-2 code

var countries = require("@notarise-gov-sg/i18n-iso-countries");
// in a browser environment: countries.registerLocale(require("@notarise-gov-sg/i18n-iso-countries/langs/en.json"));
console.log(countries.getNames("en", {select: "official"})); // { 'AF': 'Afghanistan', 'AL': 'Albania', [...], 'ZM': 'Zambia', 'ZW': 'Zimbabwe' }

Get aliases using select

// Some countries have alias names defined. `select` is used to control which
// name will be returned.
console.log("GB (select: official) => " + countries.getName("GB", "en", {select: "official"})); // United Kingdom
console.log("GB (select: alias) => " + countries.getName("GB", "en", {select: "alias"})); // UK
console.log("GB (select: all) => " + countries.getName("GB", "en", {select: "all"})); // ["United Kingdom", "UK", "Great Britain"]
// Countries without an alias will always return the offical name
console.log("LT (select: official) => " + countries.getName("LT", "en", {select: "official"})); // Lithuania
console.log("LT (select: alias) => " + countries.getName("LT", "en", {select: "alias"})); // Lithuania
console.log("LT (select: all) => " + countries.getName("LT", "en", {select: "all"})); // ["Lithuania"]
