For another middleware solution that's been around for more than a year, is modeled after Rack and WSGI, and follows the JSGI specification (which I believe is part of the CommonJS spec), be sure to check out tlrobinson's Jack - http://github.com/tlrobinson/jack . You can use Jack with Node by using node-jsgi (http://github.com/kriszyp/jsgi-node).

I wrote a server side version of Sinatra in JavaScript called Roundabout: http://github.com/boucher/roundabout/tree/master My co-founder also ported Rack to JavaScript (called Jack) http://github.com/tlrobinson/jack/tree/master Roundabout is in the process of being reworked to sit on top of jack, rather than requiring Jetty like it currently does. It's actually super simple thanks to the power of Jack.

Sinatra is definitely an interesting project. We recently "ported" it to JavaScript: http://github.com/tlrobinson/jack/blob/030685ef3de4c29c38b4e... The same webservice would be: roundabout.route({ path:"/add/{a}/{b}", get: function(){this.body = this.wildcards["a"] + this.wildcards["b"];} }) or, alternatively: roundabout.get("/add/{a}/{b}", function(){ this.body = this.wildcards.a + this.wildcards.b; }); The first syntax is a tad longer, but its much more useful; you can define any method with the name of an HTTP verb for that path, and you can also define a filter parameter that will be queried before the path is matched. The filter lets you do whatever pre-processing you want, so you could filter out requests from a specific user-agent for example, or all URLs that use mixed case, or anything else you can think of.

Plus jack and roundabout (ports of rack and sinatra to javascript), because we created those too :) http://github.com/tlrobinson/jack

There's a lot of monolithic server side JavaScript packages like Helma, but I want something more modular. Also, Helma is written in mostly Java I believe, rather than JavaScript, which is ok if you don't want to hack on Helma itself (or if you know and like Java), but I'd rather have an all (or at least mostly) JavaScript solution. Anyway, I started working on part of a solution for this: Jack (http://github.com/tlrobinson/jack), which is like Rack (http://rack.rubyforge.org) but for JavaScript. If you don't know, Rack/Jack are like bridges between webservers and Ruby/JavaScript web apps/frameworks, so framework/app devs don't need to worry about what server they're using, they just write to the Rack API. It also includes "middleware" which lets you pre and post process requests, which allows for neat things like intercepting some reques

Speaking of Rack ports... a JavaScript one I just started a couple days ago, called Jack of course: http://github.com/tlrobinson/jack
