Web server in CoffeeScript and Node

So, here's a first stab at a web server using CoffeeScript and Node:

# Imports.
{createServer} = require 'http'
{parse: parseUrl} = require 'url'
{readFile} = require 'fs'
{resolve} = require 'path'

# Setup.
base = "#{resolve('.')}/"
log = console.log

# Server definition.
server = createServer (request, response) ->
  reqPath = parseUrl(request.url).pathname
  filePath = ".#{reqPath}"
  status = 500
  respond = (content) ->
    response.writeHead status,
      'Content-Length': content.length
      'Content-Type': 'text/html'
    response.end content
    log "#{request.method} #{reqPath} #{status}"
  # Verify the path is local to the base!!!
  # TODO Better startsWith
  if resolve(filePath).indexOf base
    # TODO status = forbidden?
    respond("")
    return
  # Handle the request.
  if request.method is 'GET'
    readFile filePath, (err, data) ->
      if err
        if err.errno is 2
          status = 404
        data = ""
      else
        status = 200
      respond(data)
  else
    respond("")

# Start the server.
port = 8080
server.listen port, ->
  log "Running on #{port} from #{base} ..."

Not so bad. Probably could be cleaned up. I get tangled in CoffeeScript sometimes, but usually it's straightforward.

I don't drink coffee, but this is nice little scripting all right.
