A modular async web framework for node.js. Simon Willison says: "Spectacular web framework for Node.js which, despite using nothing but regular JavaScript, has syntax that is easily confused with Lisp. General consensus at work is that truly understanding how this works is a crucial step on the path to JavaScript enlightenment."

"Trying out a bit of Simon Willison's Redis Tutorial (and "Node.js is genuinely exciting" post): this node.js script reads the HTTP referer header from a request, increments appropriate counters in a Redis database, then returns a 1x1px GIF image."

""Evented I/O for V8 JavaScript"—a JavaScript environment built on top of the super-fast V8 engine which provides event-based IO functionality for building highly concurrent TCP and HTTP servers. The API design is superb—everything is achieved using JavaScript events and callbacks (even regular file IO) and the small standard library ships with comprehensive support for HTTP and DNS. Overall it’s very similar to Twisted and friends, but JavaScript’s anonymous function syntax feels more natural than the Python equivalent. It compiles cleanly on Snow Leopard. Definitely a project to watch."
