There are lots of little bits of data that you often need relating to countries, and I couldn't find any easy to use source of it. So I compiled it all here.

This code base may change a bit until it hits 0.1.x - feel free to use it, but be sure to check between upgrades.

I suspect that many of the currencies entries on the countries may be wrong. Help checking them would be appreciated.

The data currently provided for each country is:

• name The english name for the country
• alpha2 The ISO 3166-1 alpha 2 code
• alpha3 The ISO 3166-1 alpha 3 code
• status: The ISO status of the entry - see below.
• currencies An array of ISO 4217 currency codes with the primary one first
• languages An array of ISO 639-2 codes for languages (may not be complete).
• countryCallingCodes An array of the international call prefixes for this country.
• ioc The International Olympic Committee country code
• emoji The emoji of country's flag.

The status can be one of 'assigned', 'reserved', 'user assigned' or 'deleted'.

Assigned means that the code is properly in the ISO 3166 standard. Reserved means that the code is being prevented from being used. Deleted means that it has been deleted. User Assigned means that for some use cases it is required. Deleted means that it used to be in the standard but is now not.

See https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 for full details, especially the "User-assigned code elements" and "Reserved code elements" sections.

Countries are ofter grouped into regions. The list of regions is by no means exhaustive, pull requests very welcome for additions.

• countries An array of alpha2 codes for the countries in this region.

It is not that useful to just have the currency code(s) for a country, so included is currency data too:

• name The english name for the currency
• code The ISO 4217 code
• number The ISO 4217 number
• decimals The number of decimal digits conventionally shown
• symbol The currency symbol for the currency (e.g. ¥, $ etc.). Some symbols are not available, in which case symbol contains the ISO 4217 code. Credit to bengourley/currency-symbol-map for the symbol database.

A list of languages provided by ISO 639-2;

• name The english name for the language
• alpha2 The two letter ISO 639-1 code for the language (may be blank).
• alpha3 The three letter terminological ISO 639-2 code for the language (may be blank).
• bibliograpic The three letter bibliographic ISO 639-2 code for the language (may be blank).

To make finding easier there are utility methods that can search the countries and currencies. See examples below.

npm install country-data

var countries        = require('country-data').countries,
    currencies       = require('country-data').currencies,
    regions          = require('country-data').regions,
    languages        = require('country-data').languages,
    callingCountries = require('country-data').callingCountries;

// .all gives you an array of all entries
console.log( countries.all );
console.log( currencies.all );

// countries are found using alpha2 or alpha3 (both uppercase)
console.log( countries.BE.name );        // 'Belgium'
console.log( countries.FRA.currencies ); // ['EUR']

// callingCountries is like countries but only has entries with dialing codes.

// currencies are accessed by their code (uppercase)
console.log( currencies.USD.name ); // 'United States dollar'

// regions are accessed using a camel case name
console.log( regions.europe.countries )

var lookup = require('country-data').lookup;

// Match a value (grab first from array)
var france = lookup.countries({name: 'France'})[0];

// Or match one of several possible values.
var eurozone_countries = lookup.countries({currencies: 'EUR'});

It is very simple for now - feel free to contribute more helpful accessors.

More data for each country is most welcome. Obvious things that it might be nice to add are:

• Wikipedia links
• Coordinates (centroid, bounding box, etc)

• other currency that it is pegged to

As this code loads the data from JSON files you need to add the JSON loader to webpack:

npm install json-loader --save-dev

and then include in your webpack.config.js:

// ...
   loaders: [
      // other loaders
      { test: /\.json$/, loader: 'json' },
  ],
// ...

• libphonenumber "Google's common Java, C and Javascript library for parsing, formatting, storing and validating international phone numbers."

The final format is JSON, but it is easier to work with CSV. Hence in the data folder there are CSV files and scripts that convert them to JSON. Please don't edit the JSON directly, but do it via the CSV.

These are the steps required:

# Clone the repo (or better your fork of it)
git clone https://github.com/OpenBookPrices/country-data.git
cd country-data

# install the dependencies
npm install .

# Edit the countries.csv
open data/countries.csv

# Convert the raw data (CSV or JS files) to JSON
make

# Run the tests
mocha

# If all is ok commit and push
git add .
git commit
git push

# Then send a pull request with your changes. Ideally use several small commits,
# and reference a source that backs up the change.

The currency data was copied from the Wikipedia ISO 4217 page.

The country calling codes came from the Wikipedia country calling codes page.
