var http = require('http')
var paramify = require('paramify')
 
http.createServer(function (req, res) {
 
  var match = paramify(req.url)
  res.writeHead(200, {'Content-Type': 'text/plain'})
 
  if (match('intro/:greeting')) {
 
    intro(match.params, res)
  }
  else if (match('showtimes/:start/:end')) {
 
    showtimes(match.params, res)
  }
  else if (match('files/*')) {
  
    serveFile(match.params, res)
  }
  
}).listen(1337, '127.0.0.1')
 
function intro(params, res) {
 
  res.end('Greeting was "' + params.greeting + '"\n')
}
 
function showtimes(params, res) {
 
  var message = [
    'Show starts at', params.start, 
    'and ends at', params.end
  ].join(' ') + '\n'
 
  res.end(message)
}
 
function serveFile(params, res) {
  // match.params contains numeric keys for any
  // path components matched with *
  fs.createReadStream(__dirname + '/static/' + params[0]).pipe(res)
}
