dnode chain workers sample

client.js

var dnode = require('dnode');

var main = function (remote) {
    remote.sumaQuadratica(4, 3, function (res) {
							console.log(res);
							worker1.end();
						}
				);
}

var worker1 = dnode.connect(5001);
worker1.on('remote', main);

worker1.js

var dnode = require('dnode');

var main = function(remote) {
	var worker1 = dnode(
		{
			sumaQuadratica : function (a, b, callback) {
				console.log(a, b);
				var args = a * a + b * b;
				remote.sqrt(args, callback); 
			}
		}
	);
	worker1.listen(5001);
}

var worker2 = dnode.connect(5002);
worker2.on('remote', main);

worker2.js

var dnode = require('dnode');

var worker2 = dnode({
    sqrt : function (arg, callback) {
		console.log(arg);
        callback(Math.sqrt(arg));  		
	}
});

worker2.listen(5002);

Start worker2, then worker1 and finally client.

client will send a request to worker1 who will partially solve the function and partly will delegate to worker2. After that, worker2 will return control to client by callback.

Remote callback resolution by dnode. So you need to:

{{npm install dnode}}
