Nodejs tcp server and client example

This is a simple tcp server and client implementation using nodejs API. This just uses basic nodejs 'net' API.

Prerequites for running server and client

You just need to install nodejs on your machine.

Starting Server

Run the following command on the terminal

$node groupChatServer.js

Server will start running and you should see the following print on the terminal.

Server listening on 127.0.0.1:8765

Server will bydefault listen on 127.0.0.1, a loopback interface. If you want to change to any other address(you should be to accept connections from other hosts) change SERVER_HOST in the groupChatServer.js to which ever the address you want, also the port number 8765 to something else if you want.

Starting Client

Now the server is listening for user connections, start client on the other terminal.

start the client as follows.

$node groupChatClient.js [your name]

'your name' will be sent as sender for all your messages. If you omit 'your name', user name will be 'unknown'.

Now you should see the following prompt.

me>

And you can type your message here and it will be broadcast to the all users who have connected to the server using the client.
