对多个Javascript文件使用构造函数

我试图在我的javascript程序中实现一些oop，所以基本上我有这个项目结构

src
|_model
|    |_Amministratore.js
|_main.js

我在amministorare.js中有以下代码

///Rappresenta un amministratore di sistema
const Storage = require("../PersistanceStorage");

function Amministratore(info) {

  this.email = info.email;
  this.password = info.password;
  this.nome = info.nome;
  this.cognome = info.cognome;
  this.role = "admin";

  this.aggiungiID = function(ID) {
    this.ID = ID;
  };

  //Ritorna il path del nodo
  this.path = function() {
    return "Admin";
  };

  //Restituisce la versione memorizzabile nel
  this.getUploadableVersion = function() {
    return {
      [ID]: {
        nome: this.nome,
        cognome: this.cognome
      }
    };
  };

现在，在main.js中，我有一段代码：

exports.postAdmin = functions.region(REGION).https.onRequest((req, res) => {

  const adminData = req.body;

  if (adminData === null || adminData === undefined) {
    return res
      .status(400)
      .send(impacchettaInformazioni(null, "must provide a body!", 400));
  }

  const admin = new model.Amministratore(adminData);

  return admin
    .postAmministratore()
    .then(function() {
      return res
        .status(200)
        .send(impacchettaInformazioni(null, "Admin created!", 200));
    })
    .catch(err => {
      return rej
        .status(500)
        .send(impacchettaInformazioni(null, err.message, "500"));
    });

});

但我一直在犯这样的错误：

TypeError: model.Amministratore is not a constructor
    at exports.postAdmin.functions.region.https.onRequest (/srv/index.js:311:17)
    at cloudFunction (/srv/node_modules/firebase-functions/lib/providers/https.js:57:9)
    at /worker/worker.js:783:7

    at _combinedTickCallback (internal/process/next_tick.js:132:7)
    at process._tickDomainCallback (internal/process/next_tick.js:219:9)

我错过什么了吗？我是否需要某种module.export，就像我在另一个文件中导出某些函数一样？谢谢您的帮助。

您需要在

amministorare.js

exports.Amministratore = Amministratore

然后在

main.js

文件中需要它

const model = require('./model/Amministratore.js')

该

模型

来自何处？什么是

模型.amministore

？确切地说，您需要导出函数
