Angular multilanguage app

Question

I'm trying to create a multilanguage Angular app. I want to use angular-translate , but I don't understand how it works. I have a json which I get using $http.get , recieved data I write it to $scope and using ng-repeat and etc. output data in view. How can I output data using translate? I want to get translations from json files and use same json structure as in example if it possible. Looking for advices.

Angular app

(function(){

    var app = angular.module('webApp', []);

    app.controller('InfoCtrl', function($scope, $http){
        $scope.services = [];
        $scope.gallery = [];
        $scope.clients = [];


        $http.get('assets/translations/translate.json').success(function(data) { 
            // console.log("success!");

            $scope.services = data[0].services;
            $scope.gallery = data[1].gallery;
            $scope.clients = data[2].clients;
    });  

    });

})();

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.
