node-ice

This project provides a bridge from Node.JS to the ZeroC ICE RPC framework.

Project tested only on Windows platform (Visual Studio 2010) with Node.JS 0.10.1, ZeroC Ice 3.5.0.

This is an obsolete project, for modern Node.JS enviroument use https://github.com/zeroc-ice/ice

What follows is a simple example.

Server slice declarations:

module Monitoring
{
	sequence<byte> ByteArray;

	struct Options
	{
		long params;
		string userid;
		double modifytime;
	};

	interface Service
	{
		void shutdown();
		idempotent string echo(string msg, optional(1) int delay, optional(2) Options opt);
	};
}

Ice client node.js implementation code:

var ice = require('ice');

/**
* javascript analog slice declarations
*/
var Monitoring = (function(){
	var ByteArray = ice.Sequence('byte');
	var Options = {
		params: 'long',
		userid: 'string',
		modifytime: 'double'
	}
	var Service = {
		shutdown: ice.Method(),
		echo: ice.Method('string', ice.mode.idempotent, [
			ice.Argument('msg', 'string'), 
			ice.Argument('delay', 'int', 1),
			ice.Argument('opt', Options, 2)
		])
	}
	return {
		ByteArray: ByteArray,
		Options: Options,
		Service: Service
	}
})();

/**
* initialize ice communicator
*/
var communicator = 
	// from parameters
	new ice.Communicator({
		"Service.Proxy": "service:tcp -h localhost -p 10000:udp -h localhost -p 10000",
		"Ice.Trace.Network": 1,
		"Ice.Trace.Protocol": 1
	});
	
	// or from configuration file
	//new ice.Communicator('./test.conf');
	
/**
* create ice object proxy
* examples:
*     // from configuration property
*     communicator.propertyToProxy('Service.Proxy', Monitoring.Service);												
*     // from string
*     communicator.stringToProxy('service:tcp -h localhost -p 10000:udp -h localhost -p 10000', Monitoring.Service);	
*/
var service = communicator.propertyToProxy('Storage.Proxy', Monitoring.Service);

/**
* invoke ice object methods
* examples: 
*    service.echo("Hello"); 
*    service.echo("Hello", 5000, {userid:'guest'});
*    service.echo("Hello", null, [0, 'guest']));
*/
var result = service.echo("Hello", 1000);
service.shutdown();

ToDo:

- Application terminated in release mode; 

- Implemets ice class & ice user exception; 

- Test optional parameters: with sequence, with dictonary, at the begin of definition, on reordering tags;

- Automatically parsing slice file into javascript

- Implements server features

- Compatibility with Linux/Unix 

- Search memory leaks;
