Hi everyone! I'm new to node red and want to create customise node to to control my remote device. I would like to start with the functionalities of tcp request node. And later gradually add functions to it. Is there any link where I can check the code(tcp request)? Or any link where I can make a start with my project in mind?

Thank you,  
Joe

I started to create a model node for my reference, a simple node that will display string to lower case and works fine. I change the function in the js file with code below

```auto
    RED.nodes.createNode(this,config);
      	var node = this;
        var net = require('net');
	var client = net.connect('7877,'192.168.1.12', function() {
	node.send('Connected!!');
	});

```

when I hit deploy there is no error but there is also no message if it successfully connected to ip address and port.
