Auto-loading express middleware, coffee-style

I like each of my middleware functions to be in separate files, and consolidated into a single directory called, you guessed it, 'middleware'.

I then simply require() my middleware.coffee auto-loader, and all my middleware is automagically loaded:

console.log 'Exporting all custom middleware'

fs = require 'fs'
path = require 'path'
basename = path.basename

exports.middleware = {}

# Auto-load middleware with getters.
fs.readdirSync("#{__dirname}/middleware").forEach (fileName) ->
 load = ->
 require "./middleware/#{moduleName}"
 return unless /\.coffee$/.test(fileName)

 moduleName = basename(fileName, '.coffee')
 exports.middleware.__defineGetter__ moduleName, load
 exports.__defineGetter__ moduleName, load
