How I do global variables with CoffeeScript

app.coffee

# app.coffee
fs       = require 'fs'
express  = require 'express'
tasty    = require './tasty.js'
app      = express.createServer()
md       = require("node-markdown").Markdown

firstArticleData = ''
articleList      = []
fs.readdir 'articles', (err, files) ->
  globals.articleList = files
  fs.readFile 'articles/' + globals.articleList[0], (err,data) -> firstArticleData = md(new String(data))

app.configure ->
  app.use express.staticProvider(__dirname + '/public')
app.set 'view engine', 'jade'

app.get '/', (req,res) ->
  res.render 'index', { locals: { article: firstArticleData, list: globals.articleList } }

app.get '/:year/:month/:day/:title', (req,res) ->
  articleUrl = [req.params.year, req.params.month, req.params.day, req.params.title].join('-')
  fs.readFile 'articles/' + articleUrl + '.markdown', (err,data) ->
    res.render 'index', { locals: { article: md(new String(data)), list: globals.articleList } }

app.listen 3000

tasty.js

// tasty.js, where I define a global variables holder
globals = {};

It works, thanks!

Thanks as 2023 it's used by me to learn.
