以打字稿的形式导出

It's ugly and hacky, but you can still do:

class Greeter {}
declare var exports:any;
exports = Greeter;

Which compiles into:

var Greeter = (function () {
function Greeter() { }
return Greeter;
})();
exports = Greeter;

So I think I've found a workaround. Just wrap the keyword 'module' in parentheses in your .ts file:

declare var module: any;
(module).exports = MyClass;

The generated javascript file will be exactly the same:

(module).exports = MyClass;

Note, better than declaring var module yourself, download the node.d.ts definition file and stick it in the same directory as your typescript file. Here is a complete sample of an express node.js routing file which assumes node.d.ts is in same directory:

/// <reference path="node.d.ts" />
var SheetController = function () {
this.view = function (req, res) {
res.render('view-sheet');
};
};
(module).exports = SheetController;

I can then new up a SheetController and (using express) assign the view method:

var sheetController = new SheetController();
app.get('/sheet/view', sheetController.view);

I suppose any keyword can be escaped using this pattern:

declare var reservedkeyword: any;
(reservedkeyword).anything = something;

This has now been implemented and is ready in TypeScript 0.9 :)

You can export a single class in TypeScript like this:

class Person {


private firstName: string;
private lastName: string;


constructor(firstName: string, lastName: string) {
this.firstName = firstName;
this.lastName = lastName;
}


public getFullName() {
return `${this.firstName} ${this.lastName}`;
}
}


export = Person;

And here is how it's going to be used:

var Person = require('./dist/commonjs/Person.js');


var homer = new Person('Homer', 'Simpson');
var name = homer.getFullName();


console.log(name); // Homer Simpson

To be complete, here is my tsconfig.json (I am using TypeScript v2.0.3):

{
"compilerOptions": {
"module": "commonjs",
"moduleResolution": "node",
"outDir": "dist/commonjs",
"rootDir": "src/ts",
"target": "es5"
},
"exclude": [
"dist",
"node_modules"
]
}
