Define AngularJS services using provider, factory and service

services.js

'use strict';

/* Services */


// Demonstrate how to register services
// In this case it is a simple value service.
var servicesModule = angular.module('myApp.services', []).value('version', '0.1');

servicesModule.factory('Foo', function () {
	var Klass = function () {};
	Klass.prototype.value = 123;
	return Klass;
});

servicesModule.factory('Quxx', function (Foo) {
	return function () {
		console.log("Quxx factory: " + (new Foo()).value);
	}
});

services2.js

var servicesModule2 = angular.module('myApp.services2', ['myApp.services']).value('version', '0.1');

// factory
servicesModule2.factory('barFactory', function (Foo) {
	return function () {
		console.log("factory: " + (new Foo()).value);
	}
});

// provider
servicesModule2.provider('barProvider', function () {
	this.$get = function (Foo) {
		return function () {
			console.log("provider: " + (new Foo()).value);
		};
	};
});

// service
servicesModule2.service('barService', function (Foo) {
	this.run = function () {
		console.log("service: " + (new Foo()).value);
	};
});
