I’m working on a library for sending messages between browsers using JavaScript, XMLHttpRequest, and PHP/sqlite on a server. The idea is that even though it’s not possible to open a connection of sorts directly between the clients (i.e. web browsers viewing a page, or even different pages, or running a widget), you can pull for updates in a way that will make it seem like you have a connection open. Not only that, but all client listening on the same channel, so to speak, will receive the messages, so it’s like broadcasting. Technically this is nothing fancy, it’s just that you don’t see it much, and if implemented and packaged nicely I think it’ll be useful and fun to use.
How do I know this works? Because it’s based on a much cleaned up version of the code used on paintmyblog.com – which has proven itself already. I look forward to writing some cool apps using this library, and I hope other people will use it as well. Expect the first release next week.
