my usual coffeescript expressjs preamble

express-server.coffee

FS         = require  'fs'
express    = require  'express'
joinPath   = require( 'path'  ).join
redis      = require( 'redis' ).createClient()
RedisStore = require( 'connect-redis' )( express )
server     = express.createServer()
fetcher    = require './fetcher'
  
# create "temp dir"
try FS.mkdirSync( joinPath( __dirname, '..','tmp' ) , 0755 ) catch ignore

server.configure ->
    server.use express.methodOverride()
    server.use express.cookieParser()    
    server.use express.bodyParser()
    server.use express.session { 
      secret: "≈≈≈≈≈≈≈≈≈≈Nyan!", store: new RedisStore 
    }
    server.use server.router

server.configure 'development', ->
    server.use express.static joinPath __dirname , '..', 'static' 
    server.use express.errorHandler { 
      dumpExceptions: true
      showStack: true
    }
