making node.js net client

Question

In all the examples of creating a client for node.js built-in net module I don't see how they get net to run on the client with out downloading it??

surely if my client-side code starts like this:

var net = require('net');
var client = net.connect({port: 8124},function(){
   console.log('client connected');
   client.write('world!\r\n');
   });

then first i must write:

<script src="some strange node path to net ??"></script>

am i correct? how do I do this? btw: node.js is installed in my root on my server not local

What are you trying to achieve? Call a node server from a browser, or from another node instance? — Joachim Isaksson

not with socket.io (i don't like voodoo) i want to understand by building something simple myself — Ben Muircroft

yes and also how to use it to ceate the client in the browser for two way communication... im also looking at ajax and the http module scratching my head! — Ben Muircroft

I believe there's a bit of confusion here. The client example code you're showing is meant to run in node, not in the browser. That makes node a client of another (node or otherwise) TCP server.

If you want node to be the client and connect to another server over TCP, then run the code you're pasting. The net module is bundled with node, you're good to go.

If, however, you want your browser to talk to a node server then this would have to be over websockets (a streaming binary protocol over http, this is not plain-vanilla TCP). You would have to have a websockets module in the server, not plain net.

Just to be clear: net is simply node's interface to TCP sockets.

I am very confused because of one web page rhuno.com/flashblog/2011/05/22/… (btw, I am not intending to use flash). all i see here is 1) bidirectional communication. 2) only net module. Someone please explain how. This is messing my head up! google says nothing on stupid asp.net stuff nothing for node.js unless you want express or socket.io
