FormatJS – Internationalize Your Web Applications

FormatJS is a modular collection of JavaScript libraries for internationalization that are focused on formatting numbers, dates, and strings for displaying to people. It includes a set of core libraries that build on the JavaScript Intl built-ins and industry-wide i18n standards, plus a set of integrations for common template and component libraries.

FormatJS has been tested in all the major browsers on both desktop and mobile devices. Careful attention has been applied to make sure the libraries work in ES3 browsers all the way down to IE 6. For many web apps rendering happens on the server, so they made sure FormatJS works perfectly in Node.js. This allows developers to use FormatJS on both the server and client-side of their apps.
