HTML5 Server Sent Events
Here you will learn about Server-Sent Events which used when you need to be
displayed data immediately to the end-user without refreshing the web page.
When you need to display real-time data (Latest update from server) on the web page,
but without refreshing the page you need to use Server-Sent Events. As, to get
the latest update from server we need to refresh the browser, but somewhere like
Facebook/Twitter updates, stock price updates, etc websites you also might need to display the latest real-time data on the web page. Server-Sent Events are
supported in all major browsers, except Internet Explorer.
The first thing you have to do is to create an EventSource object and give it a URL to listen which is must needed In order to listen to an event on the client-side.
EventSource is a reference to a server-side source that dispatches the events
(the generic handler in this case).
