📦 Installation

You can install the package via npm or yarn:

npm install countries-data-kit

or

yarn add countries-data-kit

🚀 Usage

The main function, getCountries({ fields:[], filters:{}|[] }), retrieves country details based on two parameters:

1. fields: Specify which country data you want, such as mobile number mask, capital, or dialing code. Use the CFields enum or pass a string array.

2. filters: Define criteria to filter countries, like continent, alpha-2/alpha-3 code, name, or dialing number.

This setup gives you control over the data you receive and how countries are selected.

Importing the Package

For Node.js:

const { getCountries, SFields, CFields } = require('countries-data-kit');

For ES6 Modules or React/React Native:

import { getCountries, CFields, SFields } from 'countries-data-kit';

📚 Examples

Example 1: Retrieve All Countries with Full Data

To get data for all 249 countries, simply call the getCountries function:

const countries = getCountries();
or
const countries = getCountries({});

---

Example 2: Select Specific Fields to Retrieve

If you only need certain fields, such as phone number details, you can specify them using the fields parameter:

const countriesPhoneNumberDetails = getCountries({
    fields: [
        CFields.dialingCode,
        CFields.phoneNumberMask
    ]
});

Alternatively, you can pass them as strings:

const countriesPhoneNumberDetails = getCountries({
    fields: [
        "dialingCode",
        "phoneNumberMask"
    ]
});

---

Example 3: Filter Countries by Specific Criteria

To filter countries by certain criteria, such as continent or country code, use the filters parameter.

Get all Asian and European countries:

const asianCountries = getCountries({
    filters: [
        SFields.continentNames.Asia
    ]
});

or

const asianCountries = getCountries({
    filters: {
        continentName:"Asia"
    }
});

or

const asianCountries = getCountries({
    filters: {
        continentName:["Asia"]
    }
});

You can also filter by specific country codes:

let countries = getCountries({
    filters: {
        alpha2Code: ["US", "CA", "EG", "JP"]
    }
});

---

Example 4: Combine Filters and Fields for Specific Data

You can combine fields and filters to retrieve specific data. For example, to get the capital city of Germany:

let countries = getCountries({
    fields: [CFields.capitalCity],
    filters: [SFields.countryNames.Germany]
});

or

let countries = getCountries({
    fields: [
        CFields.capitalCity
    ],
    filters: {
        countryName: "Germany"
    }
});

Retrieve in which continents specific countries exist based on their alpha3 codes:

let countries = getCountries({
    fields: [
        CFields.continentName
    ],
    filters: {
        alpha3Code: ["DZA", "AUT"]
    }
});

---

Example 5: Mix Multiple Filters for Complex Queries

You can apply multiple filters to retrieve data that meets several criteria. For example, to get all countries with Cairo as the capital, a specific flag, and those that use the Euro:

let countries = getCountries({
    fields: [CFields.continentName],
    filters: [
        SFields.capitalCities.Cairo,
        SFields.flagEmojis["🇺🇸"],
        SFields.currencyCodes.EUR
    ]
});

or

let countries = getCountries({
    fields:[CFields.continentName],
    filters:{
        capitalCity:"Cairo",
        flagEmoji:"🇺🇸",
        currencyCode:"EUR"
    }
})

the above call will return all countries that use Euro + Egypt + USA

🔍 Filtering Methods

1. Filter Using an Array of SFields Values:

This method allows you to filter countries by providing an array of values from the SFields mappings.

• Example:

  const filteredCountries = getCountries({
    filters: [SFields.alpha2Codes.US, SFields.continentNames.Africa]
  });

• SFields Table:

  Field	How to Access
  alpha2Codes	SFields.alpha2Codes
  alpha3Codes	SFields.alpha3Codes
  capitalCities	SFields.capitalCities
  continentNames	SFields.continentNames
  countryNames	SFields.countryNames
  currencies	SFields.currencies
  currencyCodes	SFields.currencyCodes
  dialingCodes	SFields.dialingCodes
  drivingSides	SFields.drivingSides
  flagEmojis	SFields.flagEmojis
  numericCountryCodes	SFields.numericCountryCodes
  phoneNumberMasks	SFields.phoneNumberMasks
  primaryLanguages	SFields.primaryLanguages

2. Filter Using an Object for More Control:

This method provides more control by allowing you to specify filters as key-value pairs, where the keys correspond to the filter object keys and the values are the criteria you want to filter by.

• Example:

  const filteredCountries = getCountries({
    filters: {
      continentName: ["Europe", "Asia"],
      alpha2Code: "EG"
    }
  });

• Filter Object Key Table:

  Filter Object Key	Example
  alpha2Code	"EG"
  alpha3Code	"USA"
  capitalCity	"Cairo"
  continentName	["Europe", "Asia"]
  countryName	"United States of America"
  currency	"Egyptian pound"
  currencyCode	"USD"
  dialingCode	["+20", "+1"]
  drivingSide	"right"
  flagEmoji	"🇪🇬"
  numericCountryCode	"840"
  phoneNumberMask	"(###) ###-####"
  primaryLanguage	["English", "Arabic"]
