In AngularJS, there are three ways to register a service in a module.<\/p>\n
We can register a service via Angular module\u2019s “factory” function. This is commonly use to register a service.<\/p>\n
[java]
\nvar myApp = angular.module(‘myApp’, []);
\nmyApp.factory(‘MyService’, function() {
\n\treturn {
\n\t\tmessage: ‘Test message from MyService.’
\n\t}
\n});
\n[\/java]<\/p>\n<\/li>\n
[java]
\nvar TestController = function($scope, MyService) {
\n $scope.myService = MyService;
\n};
\nmyApp.controller(‘TestController’, [‘$scope’, ‘MyService’, TestController]);
\n[\/java]<\/p>\n<\/li>\n
[html]
\n<div ng-controller="TestController">
\n <p>{{myService.message}}<\/p>
\n<\/div>
\n[\/html]<\/p>\n<\/li>\n<\/ul>\n<\/li>\n
We can register a service via Angular<\/a> module\u2019s “config” function. This makes service to be configurable via $get function which is called once when service instance is created (because services by default are Singletons). This is often used in mocking service in unit tests.<\/p>\n [java] [java] [html] A service function is a constructor function, it creates the object using “new” keyword. We can add properties and functions to a service object by using “this” keyword and it doesn\u2019t return any object.<\/p>\n [java] this.reverseMessage = function() { [java] [html] Hope this helps !!!<\/p>\n Read Further on AngularJS Series<\/span><\/p>\n In AngularJS, there are three ways to register a service in a module.
