A simple NPM package to search for country information based on various codes and names. This package provides methods to search for countries by FIPS code, ISO code, internet code, and country name.

Built on Typescript for the best developer experience.

Acknowledgements

Credit to richorama/country-code-lookup for the base country data and the original scaffold for this package. The original package was converted to Typescript and was restructured with a class-based approach to provide an alternative to the original package. Note that this original package contains types, so please choose the package that best suits your needs/development style.

Installation

Install the package using npm:

npm install @apollo-tech/country-codes

Usage

Import the package and use the provided methods to search for country information.

import CountryCodes from '@apollo-tech/country-codes';

const countryCodes = new CountryCodes();

// Search for a country by FIPS code
const countryByFips = countryCodes.byFips('US');
console.log(countryByFips);

// Search for a country by ISO code
const countryByIso = countryCodes.byIso('USA');
console.log(countryByIso);

// Search for a country by internet code
const countryByInternet = countryCodes.byInternet('US');
console.log(countryByInternet);

// Search for a country by name
const countryByName = countryCodes.byCountry('United States');
console.log(countryByName);

Methods

FIPS Codes

Search for a country by FIPS code.

byFips(code: string): CountryResponse

ISO Codes

Search for a country by ISO code. This method supports ISO2, ISO3, and ISO numeric codes. If you provide an invalid ISO code type, the method will throw an error. You can enable safeMode to prevent the method from throwing an error and return null instead.

byIso(code: string | number, safeMode: boolean = false): CountryResponse

Internet Codes

Search for a country by internet code.

byInternet(code: string): CountryResponse

Country Name

Search for a country by name. This method is case-sensitive by default. Enable ignoreCase to perform a case-insensitive search.

byCountry(country: string, ignoreCase: boolean = false): CountryResponse

Response (Country)

All methods return a CountryResponse object which is either a Country object or null.

For simplicity of use, below is the structure of the Country object:

interface Country {
    continent: string;
    region: string;
    country: string;
    capital: string;
    fips: string;
    iso2: string;
    iso3: string;
    isoNo: number;
    internet: string;
}

The Country object contains the following properties:

• continent - The name of the country's continent.
• region - The region of the country.
• country - The name of the country.
• capital - The capital of the country.
• fips - The FIPS code of the country.
• iso2 - The ISO-3166-alpha-2 code of the country (2-char code, like US).
• iso3 - The ISO-3166-alpha-3 code of the country (3-char code, like USA).
• isoNo - The ISO-3166-num-3 code of the country (3-digit numerical ccode, like 840).
• internet - The internet code of the country (2-char code, like US).

Which code should I use?

In general, if you are asked for a two-digit code, use the ISO2 code. If you are asked for a three-digit code, use the ISO3 code.

The other code types are provided, but it is likely you will know which code you need based on the context in which you are asked for it. It's unlikely you will need to use the FIPS code or internet code unless specifically asked for them.

Roadmap

This package is a simple utility package and is unlikely to have any major updates. If you have any suggestions or feature requests, please open an issue on GitHub. That said, time permitting, we will likely add the following features:

• Continent-based searches (e.g., get all countries in Europe).
• Region-based searches (e.g., get all countries in the Middle East).
• List Continents and Regions.
• Add more country information (e.g. phone code, currency, etc.).
  • Searching by these additional fields is likely to be included.

Versioning

This package uses Semantic Versioning. For the versions available, see the Releases on this repository. Due to the nature of this package, it is unlikely to have any major updates, so the versioning will likely remain at 1.x.x.

We maintain semver by utilizing Conventional Commits via the Commit Lint package. This allows us to automatically generate the version number based on the commit messages, using the Release Please GitHub Action. Due to this, releases are automatically generated when a new commit is pushed to the main branch. The release is then published to the NPM registry. This could mean that the GitHub release and the NPM package version are not in sync for a short period of time.

If a future utility were to be added that significantly changed the nature of the package, we would likely create a new package with a different name to avoid complicating the existing package.

Contributing

Contributions are welcome! If you have any suggestions, bug reports, or feature requests, please open an issue on GitHub.

For code contributions, please fork the repository and submit a pull request. Please ensure that your code is well-documented and that you have added tests for any new features or bug fixes. While this repository does not have a strict code style guide, you should aim to match the existing code style as closely as possible.
