Currently i am using jquery ajax request in setinterval to pull data from a php script which gets me the latest notifications for the logged in user in realtime using set interval but somehow i fee since setinterval has to keep on going and running the script without even knowing whether there is something new to pull or not is just a waste of resources and even slows down the browser sometimes for other ajax requests in parallel... Can somebody help me to solve this using nodejs where it automatically sends the data to the html element only when there is data for him... Kind of push notification...
