Installation

npm install @innovayse/geo-atlas

Usage

Get all countries

import { CountriesAtlas } from '@innovayse/geo-atlas'

const countries = CountriesAtlas.getCountries()
// [{ iso2: 'AM', name: 'Armenia', native: 'Հայաստան', emoji: '🇦🇲', phone: 374, ... }]

Find a country by ISO2

const armenia = CountriesAtlas.find('AM')
// { iso2: 'AM', name: 'Armenia', translations: { hy: 'Հայաստան', ru: 'Армения' }, ... }

Get states/regions — sync (Node.js / CJS)

const states = CountriesAtlas.getStates('AM')
// [{ name: 'Yerevan', cities: [...] }, ...]

Get states/regions — async (Browser / ESM)

getStatesAsync uses dynamic import() and works in all environments including browsers:

const states = await CountriesAtlas.getStatesAsync('AM')
// [{ name: 'Yerevan', cities: [...] }, ...]

Get cities

const cities = states[0].cities
// [{ name: 'Yerevan', native: 'Երևան', translations: { ru: 'Ереван', hy: 'Երևան' }, ... }]

City Translation Fields

Each city includes:

| Field | Description | Example | |-------|-------------|---------| | name | English name | "Yerevan" | | native | Native script | "Երևան" | | translations.ru | Russian | "Ереван" | | translations.hy | Armenian | "Երևան" | | translations.fr | French | "Erevan" | | translations.de | German | "Eriwan" | | translations.zh | Chinese | "埃里温" | | translations.ar | Arabic | "يريفان" |

Supported translation keys: ru, hy, uk, ar, zh, es, fr, de, it, pt, pl, tr, ja, ko, nl

Country Fields

type Country = {
  iso2: string        // 'AM'
  iso3: string        // 'ARM'
  name: string        // 'Armenia'
  native: string      // 'Հայաստան'
  emoji: string       // '🇦🇲'
  capital: string     // 'Yerevan'
  phone: number       // 374
  latitude: string    // '40.0'
  longitude: string   // '45.0'
  translations: {
    hy: string        // 'Հայաստան'
    ru: string        // 'Армения'
    // + 15 more languages
  }
  currency: string    // 'AMD'
  timezones: Timezone[]
}

Nuxt 3 / Vite Setup

To prevent esbuild from processing the large JSON data files (which causes OOM crashes), exclude the package from Vite's dependency optimization:

// nuxt.config.ts
export default defineNuxtConfig({
  vite: {
    optimizeDeps: {
      exclude: ['@innovayse/geo-atlas']
    }
  }
})

Then use getStatesAsync for browser-side city loading:

// composables/useCountries.ts
import { CountriesAtlas } from '@innovayse/geo-atlas'

// Async — works in browser (ESM dynamic import)
const cities = await CountriesAtlas.getStatesAsync('AM')

// Sync — works in Node.js / SSR only
const cities = CountriesAtlas.getStates('AM')

Multilingual Country/City Names

type GeoLocale = 'en' | 'ru' | 'hy'

/** Get localized country name with fallback chain */
function getCountryName(country: Country, locale: GeoLocale): string {
  if (locale === 'en') return country.name
  return country.translations?.[locale] ?? country.native ?? country.name
}

/** Get localized city name with fallback chain */
function getCityName(city: City, locale: GeoLocale): string {
  if (locale === 'en') return city.name
  return city.translations?.[locale] ?? city.native ?? city.name
}

Validation

import { ValidatorAtlas } from '@innovayse/geo-atlas'

ValidatorAtlas.isValidCountry('AM')            // true
ValidatorAtlas.isValidCountry('XX')            // false
ValidatorAtlas.isValidState('AM', 'Yerevan')   // true
