This is a JSON-RPC server and client library for node.js http://nodejs.org/, the V8 based evented IO framework.

To install node-jsonrpc2 in the current directory, run:

npm install jsonrpc2

Important: If you run this command, you will get not this repository, but bitconjs repository.

Firing up an efficient JSON-RPC server becomes extremely simple:

var rpc = require('jsonrpc2');

var server = new rpc.Server();

function add(args, opt, callback) {
  callback(args[0] + args[1]);
}
server.expose('add', add);

server.listen(8000, 'localhost');

And creating a client to speak to that server is easy too:

var rpc = require('jsonrpc2');
var sys = require('sys');

var client = new rpc.Client(8000, 'localhost');

client.call('add', [1, 2], function(err, result) {
    sys.puts('1 + 2 = ' + result);
});

More documentation and development is on its way.
