สอบถาม การเรียกใช้งาน node express api บน vps ครับ

router.get('/getsomthing',(req,res) => {
    var api = require('/path/api.js');
    api.your_func1;
});

const express = require("express");
const app = express();
const cors = require("cors");
const config = require("./config");
const shop = require("./api/shop");
const staff = require("./api/staff");
const multer = require("multer");
const socket = require("./socket");
// const port = 80;
const port = process.env.port || 9990;


app.use(
  express.urlencoded({
    parameterLimit: 100000,
    limit: "50mb",
    type: "application/json",
    extended: true,
  }));

app.use(express.json());
app.set("json spaces", 2);


app.use(
  cors({
    credentials: true,
    origin: "http://localhost:3000", // URL of the react (Frontend) app
  })
);

app.use("/api/shop", shop);
app.use("/api/staff", staff);

// default route
app.get("/", (req, res) => {
  return res.send({
    error: false,
    message: "default root path",
  });
});

app.use((err, req, res, next) => {
  res.send(err.message);
});

console.log("before socket run");

app.listen(port, () => {
  const datetime = new Date();
  const message = `Server runnning on Port:- ${port} Started at :- ${datetime}`;
  console.log(message);
});
