var kiite = require( 'kiite' )
var io = kiite( server )

io.on( 'connection', function ( socket ) {
  console.log( 'client connected! ' + io.clientsConnected )

  var name = 'anon' + Math.floor( Math.random() * 1000 )

  socket.emit( 'message', '[SERVER]: Welcome, ' + name + '!' )
  socket.broadcast( 'message', '[SERVER]: ' + name + ' joined.' )

  socket.on( 'message', function ( message ) {
    socket.broadcast( 'message', name + ': ' + message )
  } )

  socket.on( 'disconnect', function () {
    console.log( 'client disconnected. ' + io.clientsConnected )
  } )
} )

server.listen( 9090, function () {
  console.log( 'server listening at *:' + server.address().port )
} )

Client

<body>
  <h2>Kiite client</h2>
  <input type="text" id="input">
  <ul id="list"></ul>
  <script src="kiite.min.js" type="text/javascript"></script>
  <script type="text/javascript">
    var io = window.kiite.connect( { port: 9090 } )

    io.on( 'message', function ( text ) {
      var el = document.createElement( 'li' )
      el.innerHTML = text.trim()
      list.appendChild( el )
    } )

    input.focus()
    input.onkeyup = function ( evt ) {
      if ( evt.keyCode == 13 ) {
        io.emit( 'message', input.value )
        input.value = ''
      }
    }
  </script>
</body>

About

Small, quick, and easy sockets/longpolling for simple needs with no external dependencies, binaries or GYP rebuilds.

Why

Other rich solutions can be too bulky to justify their use for very simple needs with long downloads, install times, rebuilds, and may have cross platform inconsistencies.
