The cldr-core npm package provides the core data from the Unicode Common Locale Data Repository (CLDR). This data includes locale-specific information such as date and time formats, number formats, and language translations. It is used to internationalize applications by providing locale-specific data.
Date and Time Formatting
This feature allows you to access locale-specific date and time formats. The code sample demonstrates how to retrieve the first day of the week for different locales.
const cldrData = require('cldr-core');
const dateFormats = cldrData.supplemental.weekData.firstDay();
console.log(dateFormats);Number Formatting
This feature provides locale-specific number formatting information. The code sample shows how to access number formatting data for the English locale.
const cldrData = require('cldr-core');
const numberFormats = cldrData.main['en/numbers'];
console.log(numberFormats);Language Translations
This feature offers translations for various languages. The code sample demonstrates how to retrieve language names in English.
const cldrData = require('cldr-core');
const languageNames = cldrData.main['en/languages'];
console.log(languageNames);Globalize is a library for internationalization and localization that leverages CLDR data. It provides a higher-level API compared to cldr-core, making it easier to format dates, numbers, and currencies, and to handle translations.
i18next is a powerful internationalization framework for JavaScript that supports translation, formatting, and pluralization. While it does not directly use CLDR data, it offers a comprehensive set of features for managing translations and locale-specific data.
Moment.js is a popular library for parsing, validating, manipulating, and formatting dates. It provides extensive support for internationalization through the moment-timezone and moment-locale packages, although it does not use CLDR data directly.
