http: require "http"

http.createServer( (req, res) ->
  res.sendHeader 200, {"Content-Type": "text/plain"}
  res.sendBody "Hello, World!"
  res.finish()
).listen 8000

puts "Server running at http://127.0.0.1:8000/"

If you are using coffee to be efficient, you might as well get rid of the last extraneous set of brackets and braces

http = require 'http'
http.createServer (req, res) ->
  res.writeHead 200, 'Content-Type': 'text/plain'
  res.end 'Hello, World!'
.listen 8000
console.log 'Server running at http://127.0.0.1:8000/'

and if you wanted to pass more options in the header array it would look like this

http = require 'http'
http.createServer (req, res) ->
  res.writeHead 200,
    'Content-Type': 'text/plain'
    'Content-Length': 12
  res.end 'Hello, World!'
.listen 8000
console.log 'Server running at http://127.0.0.1:8000/'
