pork v0.1.1

pork

pork is an improved fork for node. Instead of keeping your event loop active until you call disconnect (and thus shutting down IPC), pork keeps your event loop active only when you have active listeners.

pork is useful when you want to run services in the background that shutdown when your code has finished running.

Example

The following is an example of a program that porks a process, and sends and receives five pings/pongs. The process automatically exits after the fifth pong is received.

main.coffee

{pork} = require 'pork'
server = pork "#{__dirname}/pong.js"

pings = 0
ping  = ->
  return if ++pings > 5
  setTimeout
    server.send 'ping'
    server.once 'message', (msg) ->
      console.log msg
      ping()
  , 1000

pong.coffee

require 'pork'

process.on 'message', (msg) ->
  process.send 'pong'

Limitations

pork currently uses stdin and stdout for IPC. In the future it will be changed to use an auxiliary handle like fork.
