Chrome -> Rack javascript function loadResults() { $.ajax({ type: "GET", url: query_url, dataType: "xml", success: function(wolfram) { $.ajax({ type: "POST", url: "http://alpharack.heroku.com", data:"url=url_here&type=chrome&image_url=image_url_here”, success: function(m) { parseXml(wolfram); } }); } }); });

Wave -> Rack python form_fields = { 'type': 'wave', 'image_url': pod.getAttribute('src'), 'url': url } form_data = urllib.urlencode(form_fields) result = urlfetch.fetch( url="http://alpharack.heroku.com", payload=form_data, method=urlfetch.POST, headers={'Content-Type': 'application/x-www-form-urlencoded'} )

Rack -> Pusher ruby Pusher['stream'].trigger('new-query', { :type => params[:type], :image_url => params[:image_url], :url => params[:url] } ) Pusher -> Node javascript ﬂash fallback WebSocket.__swfLocation = "/public/js/WebSocketMain.swf"; var socket = new Pusher('appid', 'stream'); socket.bind('new-query', function(query) { //logic };

Rack -> CouchDB ruby db = CouchRest.database("http://mycouchdb.com:5984/queries") db.save_doc( { :type => params[:type], :image_url => params[:image_url], :url => params[:url], :created_at => Time.now } ) if params[:url] != nil CouchDB -> Node javascript $.getJSON("http://url.com/to/couchdb/view", function(data) { $.each(data.rows, function(i,item) { if (item.value.type == "chrome") { //display logic for a chrome query }; if (item.value.type == "wave") { //display logic for a wave query }; }); });

End result
