I wrote a module with 3 services that execute the oauth (and set the api key) for the google api and return the token object if the promise is positive.  Here is the whole working module:angular.module('gapiOAuth', []).controller('gapiOAuthController', ['$scope', function($scope){     }]).factory('gapiCredentialsSrvc', function(){                 return {        gapiClientId: 'xxx',        gapiScopeUrl: ['https://www.googleapis.com/auth/userinfo.email','https://www.googleapis.com/auth/blogger'],        gapiKey: 'xxx'    }}).factory('gapiGetTokenSrvc', ['$q','gapiCredentialsSrvc', function($q, gapiCredentialsSrvc){                    return function (){        var q = $q.defer();        angular.element(document).ready(function(){            gapi.auth.authorize({client_id: gapiCredentialsSrvc.gapiClientId, scope: gapiCredentialsSrvc.gapiScopeUrl, immediate: true}, function(response){                if(response && !response.error){                    q.resolve(response);                                } else {                    q.reject({});                                       }            });        });        return q.promise;    };}]).factory('gapiLogInSrvc',['$q','gapiCredentialsSrvc', function($q, gapiCredentialsSrvc){                return function(){        var q = $q.defer();        angular.element(document).ready(function(){            gapi.auth.authorize({client_id: gapiCredentialsSrvc.gapiClientId, scope: gapiCredentialsSrvc.gapiScopeUrl, immediate: false}, function(response){                if(response && !response.error){                    q.resolve(response);                }else{                    q.reject(response.error);                }            });        });        return q.promise;    };}]).factory('gapiSetApiKeySrvc',['gapiCredentialsSrvc', function(gapiCredentialsSrvc){             return function(){          angular.element(document).ready(function(){            gapi.client.setApiKey(gapiCredentialsSrvc.gapiKey);            return true;        });    };}])Do you think there will be security issues if I put this code I made onto the client side?How can I improve it?
