Node.js to Node.js communication

Question

How can I use the modules loaded from other Node process from another Node process.

Example I run:

node my_modules

which load MyModule

then I will run another nodejs process:

node grab_modules

which will run GrabModule

GrabModule will attempt to use the functions inside MyModule

Is this possible? And if this is possible how?

Answer 1

What you want is probably dnode:

From the README of dnode:

The server (which hosts the functions to be run):

var dnode = require('dnode');

var server = dnode({
    zing : function (n, cb) { cb(n * 100) }
});
server.listen(5050);

The client (which calls functions on the server and gets their results in a callback)

var dnode = require('dnode');

dnode.connect(5050, function (remote) {
    remote.zing(66, function (n) {
        console.log('n = ' + n);
    });
});
