node.js单击按钮，然后使用TCP/IP协议发送一些内容

Question

我是节点中的新手。我正在尝试将用户可以单击按钮的应用程序进行，并且使用TCP来送给客户端。
这是我的回声服务器(示例来自nodejs.org(

const net = require('net');
var HOST = '0.0.0.0'
var PORT = 6969;
var server = net.createServer();
server.listen(PORT, HOST);
console.log('Server listening on ' + server.remoteAddress + ':' + server.remotePort);
server.on('connection', function(socket) {
  console.log('CONNECTED: ' + socket.remoteAddress + ':' + socket.remotePort);
  socket.write('Hello from server');
  // other stuff is the same from here
  socket.on('data', function(data) {
    socket.write('reply data ' + data);
  });
});

您可以向我解释如何在另一个JS文件中获得此连接。我正在尝试制作module.exports = server，但我不明白如何从另一个文件发送信息。帮我，请

您可以尝试这样的事情：

app.js

 var HOST = '0.0.0.0'
 var PORT = 6969;
 var server = net.createServer();
 server.listen(PORT, HOST);
 console.log('Server listening on ' + server.remoteAddress + ':' + 
 server.remotePort);
 const socket = require("./controllers/socket")(server);
 app.get("/socket/connection", socket.connection);

socket.js

const net = require('net');
module.exports = function(server) {
   module.connection = function(request, response) {
     server.on('connection', function(socket) {
       console.log('CONNECTED: ' + socket.remoteAddress + ':' + 
       socket.remotePort);
       socket.write('Hello from server');
       // other stuff is the same from here
       socket.on('data', function(data) {
          socket.write('reply data ' + data);
       });
     });

   return module;
};
