NPM module should export the TypeScriptCompiler


I can't find a good way to programmatically compile TypeScript using the NPM module. What I'd like to do is the following.
npm install typescript
var TypeScript = require('typescript');
var compiler = new TypeScript.TypeScriptCompiler();
// ... do something with the compiler here

Ideally TypeScript would provide an interface similar to the coffee-script compiler module which works like this:

var coffee = require('coffee-script');
coffee.compile("a = 1");
//=> '(function() {\n var a;\n\n a = 1;\n\n}).call(this);\n'

+10 on this one. This interface is required to smoothly integrate TS with a node asset manager...

+1! I vote this as the developer of LIVEditor (live code editor for the web, at http://liveditor.com), since I guess LIVEditor will mostly like support TypeScript in the future.

Not just the compiler, also the language services, please.

'typescript.js' and friends are included in the npm package, but do not export anything.
They cannot export anything because doing so would drop them out of the global module, preventing them from other parts of the compiler, which also rely on the global module and reference path includes.

So it seems that a pre-requisite for this ticket would be to modularize the compiler (and language services), which would also be a great driver for testing and improving the external module system support.

We're looking into language extensions that will make it much easier to export the compiler. In 0.9.0, we're planning a way of saying "export = <symbol>" which would allow you to export the internal symbol/module that represents the compiler.

Doing so would be experimental in that the compiler API may change. We have not fully worked out all the scenarios to build the proper API, yet.

Any updates on this?
