A JavaScript library for internationalization and localization that leverages the official Unicode CLDR JSON data.
Globalize is a JavaScript library for internationalization and localization. It provides tools for formatting and parsing dates, numbers, and currencies, as well as for handling pluralization and message translation.
Date Formatting
This feature allows you to format dates according to different locales. The code sample demonstrates how to format a date in the 'en' locale.
const Globalize = require('globalize');
Globalize.load(require('cldr-data').entireSupplemental());
Globalize.load(require('cldr-data').entireMainFor('en', 'es'));
Globalize.locale('en');
const formattedDate = Globalize.formatDate(new Date(), { datetime: 'medium' });
console.log(formattedDate);Number Formatting
This feature allows you to format numbers according to different locales. The code sample demonstrates how to format a number in the 'en' locale.
const Globalize = require('globalize');
Globalize.load(require('cldr-data').entireSupplemental());
Globalize.load(require('cldr-data').entireMainFor('en', 'es'));
Globalize.locale('en');
const formattedNumber = Globalize.formatNumber(12345.6789);
console.log(formattedNumber);Currency Formatting
This feature allows you to format currencies according to different locales. The code sample demonstrates how to format a currency in the 'en' locale.
const Globalize = require('globalize');
Globalize.load(require('cldr-data').entireSupplemental());
Globalize.load(require('cldr-data').entireMainFor('en', 'es'));
Globalize.locale('en');
const formattedCurrency = Globalize.formatCurrency(12345.6789, 'USD');
console.log(formattedCurrency);Message Translation
This feature allows you to translate messages according to different locales. The code sample demonstrates how to translate a message in the 'en' locale.
const Globalize = require('globalize');
Globalize.loadMessages({
en: { hello: 'Hello, {name}!' },
es: { hello: '¡Hola, {name}!' }
});
Globalize.locale('en');
const message = Globalize.messageFormatter('hello')({ name: 'John' });
console.log(message);Pluralization
This feature allows you to handle pluralization according to different locales. The code sample demonstrates how to handle pluralization in the 'en' locale.
const Globalize = require('globalize');
Globalize.load(require('cldr-data').entireSupplemental());
Globalize.load(require('cldr-data').entireMainFor('en', 'es'));
Globalize.locale('en');
const pluralize = Globalize.pluralGenerator();
console.log(pluralize(0)); // 'other'
console.log(pluralize(1)); // 'one'
console.log(pluralize(2)); // 'other'i18next is a popular internationalization framework for JavaScript. It provides similar functionalities to Globalize, such as translation, pluralization, and formatting. However, i18next is more focused on providing a comprehensive solution for managing translations and is often used in conjunction with React and other frameworks.
Moment.js is a widely-used library for parsing, validating, manipulating, and formatting dates. While it does not provide as comprehensive internationalization support as Globalize, it is highly effective for date and time manipulation and formatting.
Luxon is a modern JavaScript library for working with dates and times. It is a successor to Moment.js and provides better support for internationalization, including time zone handling and locale-aware formatting.
The Intl object is a built-in object in JavaScript that provides language-sensitive string comparison, number formatting, and date and time formatting. It is part of the ECMAScript Internationalization API and offers similar functionalities to Globalize, but it is built into the JavaScript language itself.
A JavaScript library for internationalization and localization that leverage the official Unicode CLDR JSON data. The library works both for the browser and as a Node.js module.
Each language, and the countries that speak that language, have different expectations when it comes to how numbers (including currency and percentages) and dates should appear. Obviously, each language has different names for the days of the week and the months of the year. But they also have different expectations for the structure of dates, such as what order the day, month and year are in. In number formatting, not only does the character used to delineate number groupings and the decimal portion differ, but the placement of those characters differ as well.
A user using an application should be able to read and write dates and numbers in the format they are accustomed to. This library makes this possible, providing an API to convert user-entered number and date strings - in their own format - into actual numbers and dates, and conversely, to format numbers and dates into that string format.
Even if the application deals only with the English locale, it may still need globalization to format programming language bytes into human-understandable language and vice-versa in an effective and reasonable way. For example, to display something better than "Edited 1 minutes ago".
Globalize provides number formatting and parsing, date and time formatting and parsing, currency formatting, message formatting (ICU message format pattern), and plural support.
Design Goals.
Globalize is based on the Unicode Consortium's Common Locale Data Repository (CLDR), the largest and most extensive standard repository of locale data available. CLDR is constantly updated and is used by many large applications and operating systems, so you'll always have access to the most accurate and up-to-date locale data.
Globalize needs CLDR content to function properly, although it doesn't embed, hard-code, or host such content. Instead, Globalize empowers developers to load CLDR data the way they want. Vanilla CLDR in its official JSON format (no pre-processing) is expected to be provided. As a consequence, (a) Globalize avoids bugs caused by outdated i18n content. Developers can use up-to-date CLDR data directly from Unicode as soon as it's released, without having to wait for any pipeline on our side. (b) Developers have full control over which locale coverage they want to provide on their applications. (c) Developers are able to share the same i18n dataset between Globalize and other libraries that leverage CLDR. There's no need for duplicating data.
Globalize is systematically tested against desktop and mobile browsers and Node.js. So, using it you'll get consistent results across different browsers and across browsers and the server.
Globalize doesn't use native Ecma-402 yet, which could potentially improve date and number formatting performance. Although Ecma-402 support is improving among modern browsers and even Node.js, the functionality and locale coverage level varies between different environments (see Comparing JavaScript Libraries slide 25). Globalize needs to do more research and testings to use it reliably.

Globalize is designed to work both in the browser, or in Node.js. It supports both AMD and CommonJS.
Globalize uses the Unicode CLDR, the largest and most extensive standard repository of locale data.
We do NOT embed any i18n data within our library. However, we make it really easy to use. Read How to get and load CLDR JSON data for more information on its usage.

Globalize 1.x supports the following browsers:
(Current - 1) or Current denotes that we support the current stable version of the browser and the version that preceded it. For example, if the current version of a browser is 24.x, we support the 24.x and 23.x versions.
IE 8 is supported, but it depends on the polyfill of the ES5 methods below, for which we suggest using es5-shim. Alternatives or more information can be found at Modernizr's polyfills list.
npm install globalize cldr-data
var Globalize = require( "globalize" );
Globalize.load( require( "cldr-data" ).entireSupplemental() );
Globalize.load( require( "cldr-data" ).entireMainFor( "en", "es" ) );
Globalize("en").formatDate(new Date());
// > "11/27/2015"
Globalize("es").formatDate(new Date());
// > "27/11/2015"
Read the Locales section for more information about supported locales. For AMD, bower and other usage examples, see Examples section.
By downloading a ZIP or a TAR.GZ...
Click the github releases tab and download the latest available Globalize package.
By using a package manager...
Use bower bower install globalize, or npm npm install globalize cldr-data.
By using source files...
git clone https://github.com/jquery/globalize.git.If you use module loading like ES6 import, CommonJS, or AMD and fetch your code using package managers like npm or bower, you don't need to worry about this and can skip reading this section. Otherwise, you need to satisfy Globalize dependencies prior to using it. There is only one external dependency: cldr.js, which is a CLDR low level manipulation tool. Additionally, you need to satisfy the cross-dependencies between modules.
| Module | Dependencies (load in order) |
|---|---|
| Core module | cldr.js |
| Currency module | globalize.js (core), globalize/number.js, and globalize/plural.js (only required for "code" or "name" styles) |
| Date module | globalize.js (core) and globalize/number.js |
| Message module | globalize.js (core) and globalize/plural.js (if using messages that need pluralization support) |
| Number module | globalize.js (core) |
| Plural | globalize.js (core) |
| Relative time module | globalize.js (core), globalize/number.js, and globalize/plural.js |
| Unit module | globalize.js (core), globalize/number.js, and globalize/plural.js |
As an alternative to deducing this yourself, use this online tool. The tool allows you to select the modules you're interested in using and tells you the Globalize files and CLDR JSON that you need.
Globalize is the i18n software (the engine). Unicode CLDR is the i18n content (the fuel). You need to feed Globalize on the appropriate portions of CLDR prior to using it.
(a) How do I figure out which CLDR portions are appropriate for my needs?
Each Globalize function requires a special set of CLDR portions. Once you know which Globalize functionalities you need, you can deduce its respective CLDR requirements. See table below.
| Module | Required CLDR JSON files |
|---|---|
| Core module | cldr/supplemental/likelySubtags.json |
| Currency module | cldr/main/locale/currencies.jsoncldr/supplemental/currencyData.json +CLDR JSON files from number module +CLDR JSON files from plural module for name style support |
| Date module | cldr/main/locale/ca-gregorian.jsoncldr/main/ locale/timeZoneNames.jsoncldr/supplemental/timeData.json cldr/supplemental/weekData.json +CLDR JSON files from number module |
| Number module | cldr/main/locale/numbers.jsoncldr/supplemental/numberingSystems.json |
| Plural module | cldr/supplemental/plurals.json (for cardinals) cldr/supplemental/ordinals.json (for ordinals) |
| Relative time module | cldr/main/locale/dateFields.json+CLDR JSON files from number and plural modules |
(b) How am I supposed to get and load CLDR content?

Globalize's consumable-files are located in the ./dist directory. If you
don't find it, it's because you are using a development branch. You should
either use a tagged version or build the distribution files yourself.
Read installation above if you need more information on how to
download.
Globalize can be used for a variety of different i18n tasks, eg. formatting or
parsing dates, formatting or parsing numbers, formatting messages, etc. You may
NOT need Globalize in its entirety. For that reason, we made it modular. So, you
can cherry-pick the pieces you need, eg. load dist/globalize.js to get
Globalize core, load dist/globalize/date.js to extend Globalize with Date
functionalities, etc.
An example is worth a thousand words. Check out our Hello World demo (available to you in different flavors):
Globalize.load( cldrJSONData, ... )
This method allows you to load CLDR JSON locale data. Globalize.load() is a
proxy to Cldr.load().
Globalize.locale( [locale|cldr] )
Set default locale, or get it if locale argument is omitted.
[new] Globalize( locale|cldr )
Create a Globalize instance.
A locale is an identifier (id) that refers to a set of user preferences that tend to be shared across significant swaths of the world. In technical terms, it's a String composed of three parts: language, script, and region. For example:
| locale | description |
|---|---|
| en-Latn-US | English as spoken in the Unites States in the Latin script. |
| en-US | English as spoken in the Unites States (Latin script is deduced given it's the most likely script used in this place). |
| en | English (United States region and Latin script are deduced given they are respectively the most likely region and script used in this place). |
| en-GB | English as spoken in the United Kingdom (Latin script is deduced given it's the most likely script used in this place). |
| en-IN | English as spoken in India (Latin script is deduced). |
| es | Spanish (Spain region and Latin script are deduced). |
| es-MX | Spanish as spoken in Mexico (Latin script is deduced). |
| zh | Chinese (China region and Simplified Han script are deduced). |
| zh-TW | Chinese as spoken in Taiwan (Traditional Han script is deduced). |
| ja | Japanese (Japan region and Japanese script are deduced). |
| de | German (Germany region and Latin script are deduced). |
| pt | Portuguese (Brazil region and Latin script are deduced). |
| pt-PT | Portuguese as spoken in Portugal (Latin script is deduced). |
| fr | French (France region and Latin script are deduced). |
| ru | Russian (Russia region and Cyrillic script are deduced). |
| ar | Arabic (Egypt region and Arabic script are deduced). |
The likely deductibility is computed by using CLDR data, which is based on the population and the suppress-script data in BCP47 (among others). The data is heuristically derived, and may change over time.
Figure out the deduced information by looking at the
cldr.attributes.maxLanguageId property of a Globalize instance:
var Globalize = require( "globalize" );
Globalize.load( require( "cldr-data" ).entireSupplemental() );
Globalize("en").cldr.attributes.maxLanguageId;
// > "en-Latn-US"
Globalize supports all the locales available in CLDR, which are around 740. For more information, search for coverage charts at the downloads section of http://cldr.unicode.org/.

The source files are as granular as possible. When combined to generate the build file, all the excessive/overhead wrappers are cut off. It's following the same build model of jQuery and Modernizr.
Core, and all modules' public APIs are located in the src/ directory, ie.
core.js, date.js, message.js, number.js, and plural.js.
Install Grunt and external dependencies. First, install the
grunt-cli and
bower packages if you haven't before. These should be
installed globally (like this: npm install -g grunt-cli bower). Then:
npm install && bower install
Tests can be run either in the browser or using Node.js (via Grunt) after having installed the external development dependencies (for more details, see above).
Unit tests
To run the unit tests, run grunt test:unit, or run grunt connect:keepalive
and open http://localhost:9001/test/unit.html in a browser (or
http://localhost:9001/test/unit-es5-shim.html for IE8). It tests the very
specific functionality of each function (sometimes internal/private).
The goal of the unit tests is to make it easy to spot bugs, easy to debug.
Functional tests
To run the functional tests, create the dist files by running grunt. Then, run
grunt test:functional, or open http://localhost:9001/test/functional.html in
a browser (or http://localhost:9001/test/functional-es5-shim.html for IE8).
Note that grunt will automatically run unit and functional tests for you to
ensure the built files are safe.
The goal of the functional tests is to ensure that everything works as expected when it is combined.
Build the distribution files after having installed the external development dependencies (for more details, see above).
