Nodejs 部署:部署快速代码 get class 模块未找到

Question

编译打字稿文件后，我在下一个结构中得到js文件：

main directory
    public
        api
            controllers
                data-controller.js
    app.js
    package.json
    ...

app.json 代码是：

Object.defineProperty(exports, "__esModule", {
    value: true
});
const express = require("express");
const bodyParser = require("body-parser");
const data_controller_1 = require("./public/apì/controllers/data-controller");
const cors = require("cors");
let dataController = data_controller_1.DataController.bootstrap();
const options = {
    allowedHeaders: ["Origin", "X-Requested-With", "Content-Type", "Accept", "X-Access-Token"],
    credentials: true,
    methods: "GET,HEAD,OPTIONS,PUT,PATCH,POST,DELETE",
    origin: "http://127.0.0.1:3000",
    preflightContinue: false
};
const main = express();
main.get('/', function (req, res) {
    res.send('hello world11');
});
main.use(cors());
main.options("*", cors(options));
main.use('/data', dataController.GetRouter());
main.use('/', function (req, res) {
    res.send('hello world11');
});
main.use(bodyParser.json());
main.use(bodyParser.urlencoded({ extended: false }));
//main.listen(5000);
main.listen(process.env.PORT || 3000, function () {
    console.log("SUCCESSFULLY");
});

package.json 是：

数据控制器代码为：

class DataController {
}
exports.DataController = DataController;

执行节点应用程序时出现错误.js => 错误：找不到模块"./public/apì/controllers/data-controller">

我

为什么得到它？我有哪种解决方案？

Answer 1

// datacontroller file
class DataController {
}
module.exports = DataController;

---

// app.js file
const DataController = require("./public/apì/controllers/data-controller");
let dataController = new DataController();
dataController = dataController.bootstrap();
