Question

I’m trying to create declaration file for EmberJS.
I try to just create enough declaration to create the starter-kit application.

var App = Em.Application.create();

App.MyView = Em.View.extend({
  mouseDown: function() {
    window.alert("hello world!");
  }
});

I try several things like create module call Em and create interfaces inside of it but I didn’t manage to get it right.

Based on your example, this adds typing around the items you are using. I have made assumptions, such as Application.create() returns an Application – you can adjust the example as you require.

declare module Em {
    class Application {
        static create() : Application;
        MyView: View;
    }

    class View {
        static extend(extender: {}) : View;
    }
}

var App = Em.Application.create();

App.MyView = Em.View.extend({
  mouseDown: function() {
    window.alert("hello world!");
  }
});
