We’ve already had a glimpse at Server-Sent Events (also known as EventSource, and I’ll switch between the two to keep you on your toes) in my Methods of Communication article from last year. In this article, I want to delve in to more detail about the SSE API, demonstrate its features, and even show you how to polyfill browsers that lack EventSource support.

In fact, the two elements are absolutely wondrous when you combine them together. I’m going to show off a few super-simple demos using the two elements together, which should help suggest cool future projects for you fellow web authors.

The Web SQL database API isn’t actually part of the HTML5 specification, but it is part of the suite of specifications that allows us developers to build fully fledged web applications, so it was about time we dug around and checked out the deal.
