How can I use angular-resources.js to read in a JSON file through a service?

I'd follow @pkozlowski's advice and make sure the response is an array. Anyway, here's an example that loads data from a JSON file similar to what you describe in your comments. It uses ngResource and can help you put things together: http://plnkr.co/edit/Ofq7Md8udEnIhAPF1NgL?p=preview

The service

angular.module('jsonService', ['ngResource'])
.factory('JsonService', function($resource) {
  return $resource('cats.json',{ }, {
    getData: {method:'GET', isArray: false}
  });
});

Notice that isArray is set to false.

Your app and controller

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

app.controller('ctrl', function($scope, JsonService){
  JsonService.getData(function(data){
    $scope.name = data.name;
    $scope.children = data.children;
  });
});

getData is actually not needed since the Resource class gives you some useful convenience methods such a get, you can just do this

angular.module('jsonService', ['ngResource'])
.factory('JsonService', function($resource) {
  return $resource('cats.json');
});

app.controller('ctrl', function($scope, JsonService){
  JsonService.get(function(data){
    $scope.name = data.name;
    $scope.children = data.children;
  });
});
