Using this.__super__.constructor.apply(this, arguments) to call the parent constructor within the child constructor will throw an error telling you that this.super is not defined.

To call the parent constructor correctly, do this:

var MyJavaScriptClass = SomeCoffeeScriptClass.extend({
    constructor: function(){
        MyJavaScriptClass.__super__.constructor.apply(this, arguments);
    }
});

Could you please make coffee-script a devDependency rather than a regular dependency? I only today discovered that coffee-script was being pulled into my project when my builds started failing due to this issue. I personally have no need of coffee-script and would prefer that it isn't pulled in. Unfortunately, the csextends module is itself a transitive dependency five layers deep in my dependency tree, so I have no option to remove it from my code base.

I am trying to figure out how to call a method on the base class from the derived class. I have tried the code below but it cannot find A.shutdown although it is implemented. Please help.

var extend = require('csextends');

var B = extend(A, {
  shutdown: function () {
    A.shutdown.call(this);
  }
});

var instance = new B();
instance.shutdown();
