Javascript – how to run node.js client on browser

javascriptnode.js

everyone

I'm very new to node.js.
I'm trying to do a tcp server <-> client using node.js. So far so good.
The server script can be run Ok.
Also the client script can be run OK.

But the problem is I could only get the client to run from the terminal by typing command (node client.js).
The thing is I would like to run it in a browser so I could take the data received from server display on browser.

How do I do that?

Please help.

This is the client code. (I can't remember who originally created this script. I copy and paste it from somewhere but forget to bookmark from which I get the link. Sorry for not putting the credit to the owner of this script.)

var net = require('net');

var HOST = '192.168.0.88';
var PORT = 8888;

var client = new net.Socket();
client.connect(PORT, HOST, function() {

    console.log('CONNECTED TO: ' + HOST + ':' + PORT);
    // Write a message to the socket as soon as the client is connected, the   server will receive it as message from the client 
    client.write('B2\r\n');
});

// Add a 'data' event handler for the client socket
// data is what the server sent to this socket
client.on('data', function(data) {
    console.log('DATA: ' + data);
    // Close the client socket completely
    client.destroy();
});

// Add a 'close' event handler for the client socket
client.on('close', function() {
    console.log('Connection closed');
}); 

Thank you.

Node.js is not browser javascript. There are many parts of it that use OS features not available in a browser context. The way to do what you're looking to do while staying in the browser for the client, is to not use a TCP socket, but instead look into WebSockets (e.g. socket.io, which offers server and browser clients).
