Hello world " example with factory / service / provider:
var myApp = angular.module('myApp', []);
//service style, probably the simplest one
myApp.service('helloWorldFromService', function() {
this.sayHello = function() {
return "Hello, World!";
};
});
//factory style, more involved but more sophisticated
myApp.factory('helloWorldFromFactory', function() {
return {
sayHello: function() {
return "Hello, World!";
}
};
});
//provider style, full blown, configurable version
myApp.provider('helloWorld', function() {
this.name = 'Default';
this.$get = function() {
var name = this.name;
return {
sayHello: function() {
return "Hello, " + name + "!";
}
}
};
this.setName = function(name) {
this.name = name;
};
});
//hey, we can configure a provider!
myApp.config(function(helloWorldProvider){
helloWorldProvider.setName('World');
});
function MyCtrl($scope, helloWorld, helloWorldFromFactory, helloWorldFromService) {
$scope.hellos = [
helloWorld.sayHello(),
helloWorldFromFactory.sayHello(),
helloWorldFromService.sayHello()];
}<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js">script>
<body ng-app="myApp">
<div ng-controller="MyCtrl">
{{hellos}}
