m2njs

Mongrel2 has handlers, which take HTTP requests, and turns them into nicely packed and processed ZeroMQ messages for your asynchronous handlers. m2njs is a Mongrel2 handler for Node.js.

How To

This assumes you have ZeroMQ and Mongrel2 installed.

Navigate to your mongrel2 installation bin directory. Add the following to the mongrel2 configuration file:

nodejs = Handler(
  send_spec = 'tcp://127.0.0.1:9997',
  send_ident = '81b7114c-534c-4107-9f17-b317cfd59f62',
  recv_spec = 'tcp://127.0.0.1:9996',
  recv_ident = '81b7114c-534c-4107-9f17-b317cfd59f62'
)

You can change the address and port to whatever fits your need, then load your config using the following:

m2sh load -config YOUR_MONGREL2_CONF_FILE

Once configuration is loaded, start mongrel2 by issuing the following:

m2sh start -host localhost

Install m2njs using npm:

npm install m2njs

Use it in your code:

...
  var mongrel2 = require('m2njs');

  /*
    This should match the equivalent in your mongrel2 
    configuration file.
    example/nodejshandler.conf is an sample mongrel2 configuration file.
  */
  var config = {
    recv_spec: 'tcp://127.0.0.1:9996',
    send_spec: 'tcp://127.0.0.1:9997',
    identity: '81b7114c-534c-4107-9f17-b317cfd59f62'
  }

  mongrel2.connect(config.recv_spec, config.send_spec, config.identity, function(msg, reply) {
    
    //Perform some logic
    
    reply(200, headers, JSON.stringify(msg));
  });
....
