TypeScript Require Extension

This is a Node.JS require extension that enables requiring typescript modules without any preprocessing.

Install

Install via npm:

npm install typescript-require

Use

During the boot up process of your application, require typescript-require once;

require('typescript-require');

After this point, you can require any .ts module just like .js modules. typescript-require will find out and compile the TypeScript file, resolving any necessary dependencies to other scripts.

Sample

app.js

// Initialize
require('typescript-require');

// Get functions.ts
var funcs = require("./funcs.ts");
console.log(funcs.lowercase("HELLO!"));

funcs.ts

export function lowercase(val:string) {
    return val.toLowerCase();
}

export function uppercase(val:string) {
    return val.toUpperCase();
}

Module Dependencies in TS files

You can load any other TypeScript or Javascript module from your typescripts. However, you should use different methods for different modules

sample.ts

Given that there are two files, foomodule.js and barmodule.ts at the same directory as sample.ts

///<reference path='node.d.ts'/>

// Load a JavaScript module with standard Node.JS require
var foomodule = require('./foomodule.js');

// Load a TypeScript module with TypeScript module syntax
import barmodule = module('barmodule');
```

Note that the second one essentially gets compiled to a require call just like the first one. However, import ... module syntax makes it possible to use TyepScript compile time validation features (like type checking).
