A fast & light weight JS library to get countries geographical information including states, cities, iso codes, etc.

import { countryType, returnT, CityFnType } from "../types"
import { PATH, PATH_LITE } from "../utils"

export const City: CityFnType = cityHandler()
export const CityLite: CityFnType = cityHandler('lite')

function cityHandler(type?: 'lite'): CityFnType {
    const fn: CityFnType = function (cointryIso2: countryType, stateIso: string): returnT {
        if (!cointryIso2) {
            throw new TypeError("Country iso2 type missing")
        }
        if (!stateIso) {
            throw new TypeError("State iso type missing")
        }
        try {
            return require(`${type === 'lite' ? PATH_LITE : PATH}/cities/${cointryIso2}/${stateIso}/index.json`)
        } catch (e) {
            return []
        }
