How can I define dependent modules in TypeScript AMD Modules

Question

How can I define the dependent modules in a AMD Module with TypeScript, including, for instance, jQuery and underscore. Using JavaScript I do, for example, like this:

Answer 1

With the current implementation of the compiler (0.8) the way to achieve what you are seeking is the following.

test.ts:

import jquery = module("jquery");
import underscore = module("underscore");

export module A {
    console.log(jquery.$ + underscore._);
}

jquery.ts:

export var $ = null;

underscore.ts:

export var _ = null;

if you compile test.ts using the module switch:

tsc --module AMD test.ts

it will generate the following JS file for you:

define(["require", "exports", "jquery", "underscore"], function(require, exports, __jquery__, __underscore__) {
    var jquery = __jquery__;
    var underscore = __underscore__;
    (function (A) {
        console.log(jquery.$ + underscore._);
    })(exports.A || (exports.A = {}));
})

Note that if you put import statements inside the module it will note codegen correctly due to a bug. The team is currently working on a fix on that item but hopefully that shouldn't block you.
