Angular localization

An Angular library to translate messages, dates and numbers

This library is for localization of Angular v7 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, currency code, timezone 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 CLI & Material, and its source code.
