Factories and Services in Angular

factories-and-services-oop.md

Factories, and services in angular are singleton by definition. If you want to create a new instance you could always just do something like:

module.factory('myIntanceCreator', function(){
      return {
           create: function(){
                // create your instance here
            }
      };

});

Keep in mind that, contrary to popular belief you don’t need ‘class’ for true object-oriented-programming. If you get a chance, take a look at this talk:

One of it’s main points is that Javascript’s closures are actually offer a much purer form of encapsulation and OOP than even other class-based OOP languages.

In a nutshell, variables and functions defined inside of a closure are strictly private, while variables or functions that are attached to via this.myVariable = value are public.
