在创建打字稿npm包中进行类型检查

Question

我正在用typescript创建nodemodules，但是我不知道如何键入从nodejs js文件中的typescript中传递的检查输入数据。如果没有办法，用typescript而不是js创建节点模块有什么好处

添加一些代码以更好地理解

In my package index.ts 
export class SampleSDK{

    name:String ;
    constructor(name:String){
      this.name = name;
    }   

    getName(){
        return this.name;
    }


}
in index.js 

var express = require('express');
var router = express.Router();
var SampleSdk  = require("sample-sdk");
/* GET home page. */
router.get('/', function(req, res, next) {

  let  fdConnectSDK = new SampleSdk.SampleSDK(1000);
  console.log(fdConnectSDK.getName()); // this is printing 1000 instead i expect it should throw error
  res.send("HELLO")

});

module.exports = router;
