I’ve just released three new libraries to Hackage: engine-io engine-io-snap socket-io Engine.IO is a new framework from Automattic , which provides an abstraction for real-time client/server communication over the web. You can establish communication channels with clients over XHR long-polling, which works even through proxies and aggressive traffic rewriting, and connections are upgraded to use HTML 5 web sockets if available to reduce latency. Engine.IO also allows the transmission of binary data without overhead, while also gracefully falling back to using base 64 encoding if the client doesn’t support raw binary packets. This is all very desirable stuff, but you’re going to have a hard time convincing me that I should switch to Node.js! I’m happy to announce that we now have a Haskell implementation for Engine.IO servers, which can be successfully used with the Engine.IO...
