Question

How do you manually register locale data?

Answer 1

By default, Angular only contains locale data for en-US which is English as spoken in the United States of America . But if you want to set to another locale, you must import locale data for that new locale. After that you can register using registerLocaleData method and the syntax of this method looks like below,

registerLocaleData(data: any, localeId?: any, extraData?: any): void

For example, let us import German locale and register it in the application

import { registerLocaleData } from '@angular/common';
import localeDe from '@angular/common/locales/de';

registerLocaleData(localeDe, 'de');
