introduction

The module of node-i18n-iso-countries is awesome except that it does not support the traditional chinese. So, I forked the code from the original repo and made minor modification to support the traditional chinese.

i18n-iso-countries

Version 5 drops support for node 6 and 7!

i18n for ISO 3166-1 country codes. We support Alpha-2, Alpha-3 and Numeric codes from http://en.wikipedia.org/wiki/ISO_3166-1#Officially_assigned_code_elements

Installing

Install it using npm: npm install i18n-iso-countries

var countries = require("i18n-iso-countries");

If you use i18n-iso-countries with Node.js your are done. If you use the package in a browser environment you also have to register the languages you want to use to minimize file size.

// Support french & english languages.
countries.registerLocale(require("i18n-iso-countries/langs/en.json"));
countries.registerLocale(require("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("i18n-iso-countries");
// in a browser environment: countries.registerLocale(require("i18n-iso-countries/langs/en.json"));
console.log("US (Alpha-2) => " + countries.getName("US", "en")); // United States of America
console.log("US (Alpha-2) => " + countries.getName("US", "de")); // Vereinigte Staaten von Amerika
console.log("USA (Alpha-3) => " + countries.getName("USA", "en")); // United States of America
console.log("USA (Numeric) => " + countries.getName("840", "en")); // United States of America

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

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