SimpleRemote

Simple Remote Object implementation. It wraps up a Javascript object to use it from other process.

Installation

Via npm on Node:

npm install simpleremote

Usage

Reference it from your program:

var simpleremote = require('simpleremote');

Declare and expose an object using a server:

var obj = {
    add: function(x,y) { 
        return x + y;
    }
};

var server = simpleremote.createRemoteServer(obj);
server.listen(port);

Consuming the remote object from a client:

var client = simpleremote.createRemoteClient();
client.on('remote', function (remote) { // receives an proxy object to remote object
    remote.add(1, 2, function (err, value) {
       console.log(value); // prints 3
    };
});
client.connect(port, host);

Declare and expose an object using a client:

var obj = {
    add: function(x,y) { 
        return x + y;
    }
};

var client = simpleremote.createRemoteClient(obj);
client.connect(port, host);

Consuming the remote object from a server:

var server = simpleremote.createRemoteServer();
server.on('remote', function (remote) { // receives an proxy object to remote object at client connection
    remote.add(1, 2, function (err, value) {
       console.log(value); // prints 3
    };
});
server.listen(port);

You can combine both methods.

If the remote method to invoke has a callback as last parameter, you must declare its name at exposing the object:

var obj = {
    addAsync: function(x,y, cb) { 
        // ...
        cb(null, x + y);
    }
};

var client = simpleremote.createRemoteClient(obj, ['addAsync']);

var obj = {
    addAsync: function(x,y, cb) { 
        // ...
        cb(null, x + y);
    }
};

var server = simpleremote.createRemoteServer(obj, ['addAsync']);

TBD: Registry support.
