Can Typescript consume Existing AMD's?

Question

Dojo 1.8 already defines AMD modules. For example you can do things like this:

require(["dojo/_base/lang"], function (lang) {
  var ab = lang.mixin({a: 1}, {b: 2});
});

But how to I avoid getting an error when I attempt to import this module?

import lang = module ("dojo/_base/lang");

Is is possible?

Answer 1

You will need a typescript definition file for lang. Assuming that lang.d.ts exists in the same directory as lang.js this code:

import lang = module('dojo/_base/lang')

var ab = lang.mixin({a: 1}, {b: 2});

compiled with

tsc --module amd yourfile.ts

generates

define(["require", "exports", 'dojo/_base/lang'], function(require, exports, __lang__) {
    var lang = __lang__;
    var ab = lang.mixin({a: 1}, {b: 2});
}

If you don't want to have to match up the directory structures for whatever reason do this instead. Assuming lang.d.ts is in in a subdirectory called 3rd that is a sibling of test.ts.

test.ts:

///<reference path="3rd/lang.d.ts"/>
import lang = module('dojo/_base/lang');
var ab = lang.mixin({a: 1}, {b: 2});

3rd/lang.d.ts:

declare module 'dojo/_base/lang' {
...
}

generates the same as above.

Answer 2

You can normally load modules via the dojo loader, you don't have to use the import statement. But if you want you have to declare the module:

declare module "dojo/_base/lang" {
  export function ...
  export class ...
}
