如何使用打字稿编写节点模块？

对于Javascript：

var base = require('./base');var thing = require('./thing');module.exports = {  base: base.base,  Thing: thing.Thing};

打字稿

import base = require('./base');import thing = require('./thing');var toExport = {  base: base.base,  Thing: thing.Thing};export = toExport;

甚至这个打字稿：

import base = require('./base');import thing = require('./thing');export var base = base.base;export var Thing = thing.Thin;
