Angular multilanguage app
Angular-translate can help you internationalizing client-side strings.
How does it work
In short, you have to feed the $translationProvider with a json containing your translations:
$translateProvider.translations('en', { 'home.title': 'Welcome in my app', 'button.cancel': 'Cancel'});and then use the translate filter:
<h1>{{'home.title' | translate}}</h1><h1>{{::'home.title' | translate}}</h1> <!-- one-time binding with angular 1.3+ -->or the directive
<h1 translate="home.title"></h1><h1 translate>home.title</h1>In terms of performance prefer one of the last three syntaxes. The first one, {{'home.title' | translate}}, keeps watchers in memory.Refer to the documentation for the other features of angular-translate. Here is the getting-started guide.
Translation of the strings of the JSON you posted
Seeing the json you posted makes me think that you want to translate some service-specific strings. Their translation should be done in the back-end, i.e. the server should return the translated text according to the chosen language.
