TypeScript VS 2012 plugin is not generating JavaScript for this specific code

Question

TypeScript VS 2012 plugin is not generating JavaScript for this specific code

I'm writing this code in the editor

 ///<reference path='../node/express3.d.ts' />
 ///<reference path='../node/node.d.ts' />
import http = module('http');
var reqRecieved = function (req, res): void {
    res.end();
};
var server = http.createServer(reqRecieved);
server.listen("1337");
console.log("server started");

And the problem is that the TypeScript vs2012 plugin is not generating the JavaScript code for the same. but if I change line:

import http = module('http');

to line

var http = require('http');

then it generates fine.

what am I doing wrong here?

node.js
plugins
visual-studio-2012
typescript
web-essentials

Answer 1

I would check you have the latest version of WebEssentials 2012 installed, as there were some issues with module import code not generating in builds 1.8.*

Also, there's an oddity in TS where imports inside a module generate no code:

export module test {
    import myMod = module("MyMod"); // Generates no JS output
    var class = myMod.someClass;
}

But:

import myMod = module("MyMod"); // Outside the module. Generates JS as expected.

export module test {
     var class = myMod.someClass;
}

If you aren't getting an explanation via Visual Studio, it can sometimes help to hit the command line and see that is going on:

tsc --debug c:\path\to\yourfile.ts

This may give you more detailed errors.
