Angular - internationalization (i18n)

Question

What is the best way to implement the internationalization for a angular application at the moment?

Answer 1

The official i18n angular2 will be implemented in one of the rc release before the final release. It also will be more advanced than the current solutions.

Answer 2

At the moment the best alternative is is to use ng2-translate, which is a port to Angular 2 of the well known ng-translate. This will likelly cover the majority of use cases.

Later for Angular 2 there will be an official i18n implementation.
