Writting text over TCP socket while using javascript in node.js

This is follow up to the post: How to write a JSON File over TCP Socket in express to C++ program. For the latest update, I have chosen to send text over TCP port instead of JSON file

Summary

The task is that I have to listen to a changes in a website, (listening for a webhook). when the webhook is triggered, I have to resend it to be send out by the TCP server. The TCP server will parse the webhook content, extract the relevant data and resend it out to another TCP client (code not shown here)

var request = require('request'),
    express = require('express'),
    path    = require('path');
    http    = require('http');

// the external parser
var sf = require('./Parse');

// configuration setting
const config = {
    choice    : 1,
    http_port : 5000,
    tcp_port  : 1337,
    host      : '127.0.0.1'
};

    var portid = server.address().port

    console.log('Web App listening at http://%s:%s', host, portid)

// error handler
app.use(function (err, req, res, next) {

// Here's where you send data to all clients
function broadcast(msg) {
    console.log("broadcasting message");
    clients.forEach(function (client) {
       client.write(msg);
    });
 }

Just wondering is there anything wrong with the code... especially when seending the message... it seem to have this error

Error: This socket has been ended by the other party] code: 'EPIPE

OR how can it be improved

Thanks
