Install

bun add @suaveplan/locale-data

Quick Start

import { getCountry, getLanguage, isRtlLanguage } from "@suaveplan/locale-data";

// Country lookup
const us = getCountry("US");
console.log(us.name);      // "United States"
console.log(us.phone);     // "1"
console.log(us.emoji);     // "🇺🇸"

// Language lookup
const ar = getLanguage("ar");
console.log(ar.name);      // "Arabic"
console.log(ar.native);    // "العربية"

// RTL detection
console.log(isRtlLanguage("ar"));    // true
console.log(isRtlLanguage("ar-SA")); // true (BCP-47 tag)
console.log(isRtlLanguage("en"));    // false

API Overview

Countries

import {
  getCountry,           // O(1) lookup by ISO 3166-1 alpha-2 code
  getAllCountries,       // Returns full 209-entry Record<string, CountryItem>
  getCountriesByContinent, // Filter by continent code ("EU", "AS", "AF", etc.)
  getCountriesByCurrency,  // Filter by ISO 4217 currency code (e.g. "EUR")
} from "@suaveplan/locale-data/countries";

Languages

import {
  getLanguage,     // O(1) lookup by ISO 639-1 code
  getLanguages,    // Returns full 130+ entry Record<string, LanguageItem>
  getRtlLanguages, // Returns list of RTL language codes
  isRtlLanguage,   // BCP-47 aware RTL detection
} from "@suaveplan/locale-data/languages";

Error Handling

import { LocaleDataError, LOCALE_DATA_CODES } from "@suaveplan/locale-data/errors";

try {
  getCountry("ZZ");
} catch (err) {
  if (err instanceof LocaleDataError) {
    console.log(err.code); // "LOCALE_DATA/COUNTRY.NOT_FOUND"
  }
}

OTel Instrumentation

The package emits two OTel counters:

Metric	Attributes
`locale_data.country.lookups`	`result: "found" \| "not_found"`
`locale_data.language.lookups`	`result: "found" \| "not_found"`
