路由如何与Node.js模块一起使用？

Question

I would like to see which routes are added by a module using node.js. For instance using Socket.io, I require /socket.io/socket.io.js, yet I do not see this in my public directory or the directory of socket.io:

  <script src="/socket.io/socket.io.js"></script>
    <script>
      var socket = io.connect('http://localhost');
      socket.on('news', function (data) {
        console.log(data);
        socket.emit('my other event', { my: 'data' });
      });
    </script>

The resource loads a file when I inspect the url:

http://localhost:3111/socket.io/socket.io.js

How can I use the rails equivalent of "rake routes"?

The URL your browser requests does not have to map to a physical file on your filesystem. Socket.IO, for instance, adds scripts to your server's routes via the lib/static.js file ; check out the code and you'll see routes for JavaScripts, SWF resources, and more.
