我可以在单独的模块中路由express控制器和基本nodejs服务器

// controllers.js
exports.home = (req, res) => {
  res.send('Welcome to the home page!');
};

exports.about = (req, res) => {
  res.send('Welcome to the about page!');
};

// app.js
const express = require('express');
const app = express();
const controllers = require('./controllers');

app.get('/', controllers.home);
app.get('/about', controllers.about);

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

// server.js
const http = require('http');

const server = http.createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello World!\n');
});

server.listen(3000, () => {
  console.log('Server is running on port 3000');
});

// app.js
const server = require('./server');

server.listen(3000, () => {
  console.log('Server is running on port 3000');
});
