javascript - How to set locale in DatePipe in Angular 2?

Question

I want to display Date using European format dd/MM/yyyy but using DatePipe shortDate format it only display using US date style MM/dd/yyyy.
I'm assuming thats the default locale is en_US. Maybe I am missing in the docs but how can I change the default locale settings in an Angular2 app? Or maybe is there some way to pass a custom format to DatePipe ?

As of Angular2 RC6, you can set default locale in your app module, by adding a provider:

@NgModule({
  providers: [
    { provide: LOCALE_ID, useValue: "en-US" }, //replace "en-US" with your locale
    //otherProviders...
  ]
})

The Currency/Date/Number pipes should pick up the locale. LOCALE_ID is an OpaqueToken, to be imported from angular/core.

import { LOCALE_ID } from '@angular/core';

For a more advanced use case, you may want to pick up locale from a service. Locale will be resolved (once) when component using date pipe is created:

{
  provide: LOCALE_ID,
  deps: [SettingsService],      //some service handling global settings
  useFactory: (settingsService) => settingsService.getLanguage()  //returns locale string
}

Hope it works for you.
