Node.js + Serve Static Files with RESTIFY

Question

I have a multi-level collection of .html, .js, .png, .css, etc files in a site. A peek at my site hiearchy looks like the following:

index.html
child1
  index.html
  page1.html
  page2.html
  ...
child2
  grandchild1
    index.html
  grandchild2
    index.html
  index.html
  page1.html
  page2.html
resources
  css
    myTheme.css
  img 
    logo.png
    profile.png
  js
    jquery.js
    ...
...

I am migrating this to run under Node.js. I have been told I MUST use RESTIFY. Currently, I've written the following for my server:

var restify = require('restify');
var fs = require('fs');
var mime = require('mime');

var server = restify.createServer({
    name: 'Demo',
    version: '1.0.0'
});

server.use(restify.acceptParser(server.acceptable));
server.use(restify.queryParser());
server.use(restify.bodyParser());

server.get('/', loadStaticFile);

server.get('/echo/:name', function (req, res, next) {
    res.send(req.params);
    return next();
});

server.listen(2000, function () {
    console.log('Server Started');
});

function loadStaticFile(req, res, next) {
    var filePath = __dirname + getFileName(req);
    console.log("Returning " + filePath);

    fs.readFile(filePath, function(err, data) {
      if (err) {
        res.writeHead(500);
        res.end("");
        next(err);
        return;
      }

      res.contentType = mime.lookup(filename);
      res.writeHead(200);
      res.end(data);

      return next();
    });
}

function getFileName(req) {
    var filename = "";
    if (req.url.indexOf("/") == (req.url.length-1)) {
      filename = req.url + "index.html";
    } else {
      console.log("What Now?");
    }
    return filename;
}

With this code, I can successfully load index.html. However, my index.html file references some JavaScript, image files, and style sheets. I can see via Fiddler that that these files are being requested. However, in my node.js console window, I never see "Returing [js|css|png filename]". Its like my node.js web server returns index.html and that's it.

What am I doing wrong?

The latest versions of restify has builtin middleware serveStatic() middleware that will do this for you.

from a http://mcavage.me/node-restify/#Server-API

server.get(/\/docs\/public\/?.*/, restify.serveStatic({
  directory: './public'
}));
