Angular localization

Build Status npm version

An Angular library to translate messages, dates and numbers.

This library is for localization of Angular 2+ apps written in TypeScript, ES6 or ES5. It allows, in addition to translation, to localize numbers and dates of your app, adding language code, country code, and optionally script code, numbering system and calendar, through Internationalization API. It also implements the validation of numbers by locales.

Sample app built with Angular Material, AoT compilation & webpack, and its source code.
