How to expose angular 2 methods publicly?

Question

I am currently working on porting a Backbone project to an Angular 2 project (obviously with a lot of changes), and one of the project requirements requires certain methods

Answer 1

The problem is that Angular's components are transpiled into modules that aren't as easy to access as regular JavaScript code. The process of accessing a module's features depends on the module's format.

An Angular2 class can contain static members that can be defined without instantiating a new object. You might want to change your code to something like:

@component({...})
class MyTest {
    private static text: string = '';
    public static setText(text:string) {
        this.text = text;
    }
}
