RequireJS: How to define modules that contain a single “class”?

by

The AMD proposal allows you to just return a value for the exported object. But note that is a feature of the AMD proposal, it is just an API proposal, and will make it harder to translate the module back to a regular CommonJS module. I think that is OK, but useful info to know.

So you can do the following:

I prefer modules that export a constructor function to start with an upper-case name, so the non-optimized version of this module would also be in Employee.js

define("Employee", function () {
    //You can name this function here,
    //which can help in debuggers but
    //has no impact on the module name.
    return function Employee(first, last) {
        this.first = first; 
        this.last = last;
    };
});

Now in another module, you can use the Employee module like so:

define("main", ["Employee"], function (Employee) {
    var john = new Employee("John", "Smith");
});
