Node js Express and Simple Socket Server

Here is the thing :

I want to create an simple API Server, request from user being parsed and translated to simple socket message that transmitted to the socket server.

Here is the code

The Express Server :

var express = require('express');

var app = express(),
    handler = require('./lib/urlparser.js');

app.get('/', function(req, res){
  var body = 'Hello World';
  res.setHeader('Content-Type', 'text/plain');
  res.setHeader('Content-Length', body.length);
  res.end(body);
});

app.get('/:command/:mode/:addr/:value', handler.handleRequest);

app.listen(80);
console.log('Listening on port 80...');

And the handleRequest module

    exports.handleRequest = function(req, res) {

    var net = require('net');
    var HOST = '192.168.1.254';
    var PORT = 8888;
    var client = new net.Socket();

    /* translate the url params and save it to var request and send it */
    /* The code goes here */

        client.connect(PORT, HOST, function() {
            //console.log('Connected To: ' + HOST + ':' + PORT);
            client.setEncoding('utf-8');
            client.write(request);
            //console.log('Message Sent');
        });

        client.on('data', function(val) {
            //console.log('The Data: ' + val);
            res.send([{addr:'test'}, {value: val}]);
            client.destroy();
        });

        client.on('close', function() {
            //console.log('Connection closed');
        });

    };

This code works, I just need to know is it correct or is there any way to include the net module and declare the ip and port of the socket server inside the main js file(outside the module?

Any help would be appreciated.
