NAME

nack - Node powered Rack server

DESCRIPTION

nack is a Rack server built on top of the Node.js HTTP server. Node does all the hard work of accepting and parsing HTTP requests and nack simply passes it along to a Ruby worker process as a serialized object. You can read more about how the IPC protocol works. Besides running as a standalone Rack server, you can use the JS API to run multiple apps from the same Node process.

EXAMPLES

Simple proxy

var http = require('http');
var nack = require('nack');

var app = nack.createProcess("/path/to/app/config.ru");

http.createServer(function (req, res) {
  app.proxyRequest(req, res);
}).listen(8124, "127.0.0.1");

You can spawn up a pool of workers with:

var nack = require('nack');
nack.createPool("/path/to/app/config.ru", { size: 3 });

Workers can idle out after a period of inactivity:

// Timeout after 15m
nack.createPool("/path/to/app/config.ru", { idle: 15 * 60 * 1000 });

Theres a more friendly server API that returns a Connect application.

var connect = require('connect');
var nack    = require('nack');

connect.createServer(
  connect.logger(),
  connect.vhost('foo.test',
    nack.createServer("/u/apps/foo/config.ru")
  ),
  connect.vhost('bar.test',
    nack.createServer("/u/apps/bar/config.ru")
  )
).listen(3000);

INSTALL

You can grab the package from npm.

npm install nack

DEPENDENCIES

CAVEATS

nack was design to be used as a local development proxy. You probably don't wanna try running a production app on it. I'm sure its slow too so don't send me any benchmarks.
