Countries JS

{
  // Country's common name

    required: true
  },

    type: String,
    required: true
  },
  // ISO-3166 alpha-3
  isoA3: {
    type: String,
    required: true
  },
  // ISO-3166 numeric

Usage

Filtering

import { countries, regions, subregions } from 'countries-js'

const { Europe, Africa } = regions
const { NorthernEurope } = subregions

countries
  .include('region', [Europe, Africa])
  .exclude('subregion', [NorthernEurope])
  .exclude('isoA2', ['FR', 'ES', 'IT'])

...

Gives you a list of countries that are:

• Located in Europe and Africa
• But not located in Northern Europe
• ISO-3166 alpha-2 code not equal to FR, ES or IT

You can combine as much filters as you need to get a specific result, it's as easy as adding another include or exclude statement.

Fetching

...

countries.all // Gives all countries in a set
countries.first // Sometimes you need only the first
countries.last // or maybe the last one
