Server-Sent Events (aka EventSource) is a lightweight alternative to WebSockets, for pushing real-time messages to connected browsers.

In this talk, you'll learn the simple API for pushing events from Node or PHP (or any other server) to web browsers. This is the key to building pages that automagically update in real time (notifications, chat, collaborative editing, news tickers, social media streams, etc.)

Kornel Lesiński is a London-based web developer who participated in designing the Server-Sent Events specification at the WHATWG.
