XSocketsNodeJs Test

TODO: Change to NDC protocol and add NDC protocol tutorial

###Pre-Req

• Before running the test you should have setup a XSockets self-hosted server
• It will be easy to write this in Visual Studio since we have NodeJS-tools installed!

Code

Create a new file with nano sockettest.js and write a simple test. Replace the IP with the IP of your development machine.

var xsockets = require('xsockets.net');  
var c = new xsockets.TcpClient('127.0.0.1', 8080, ['chat']);  
var g = c.controller('chat');  
g.on('say', function(d) {  
    console.log('say',d);  
    g.send('bar','hello from nodejs');  
});        
g.onopen = function(ci) {
    console.log('connected controller chat');
    g.send('say', {text:'bar'});
}
c.onconnected = function(d) {
    console.log('connected', d);
}
c.open();

###Test

Run the test with node sockettest.js

Then open up Putty and connect to the same sever as the script, this would be the 192.168.x.x of your machine. Then type in PuttyProtocol in Putty to do a handshake. Then send a message to nodejs by typing generic|foo|hello from putty
