The HTML5 family of specs has several new communication capabilities, including XmlHttpRequest Level 2, Web Sockets, and Server-Sent Events. I can easily think of examples of web apps that I might like to build with these specs.
Edit: Here’s some examples:
- XHR2: search client, web mail, file uploader
- Web Sockets: FPS, online games, chat client, NRT traffic or weather reports
- SSE: Stock ticker, news feed, FB wall
But when it comes to the HTML5 Web Messaging spec, I can’t think of any. So what kinds of web apps might I want to build with it? TIA.
I recently found a good use case for Web Messaging. Many web apps are starting to authenticate using Facebook, so they open another tab with a Facebook login and communicate with the its contents.
Got a better use case? If so, I’ll unselect my answer.
