// express on its own has no notion
// of a "file". The express.static()
// middleware checks for a file matching
// the `req.path` within the directory
// that you pass it. In this case "GET /js/app.js"
// will look for "./public/js/app.js".

app.use(express.static(__dirname + '/public'));

// if you wanted to "prefix" you may use
// the mounting feature of Connect, for example
// "GET /static/js/app.js" instead of "GET /js/app.js".
// The mount-path "/static" is simply removed before
// passing control to the express.static() middleware,
// thus it serves the file correctly by ignoring "/static"
app.use('/static', express.static(__dirname + '/public'));

// if for some reason you want to serve files from
// several directories, you can use express.static()
// multiple times! Here we're passing "./public/css",
// this will allow "GET /style.css" instead of "GET /css/style.css":
app.use(express.static(__dirname + '/public/css'));

// this examples does not have any routes, however
// you may `app.use(app.router)` before or after these
// static() middleware. If placed before them your routes
// will be matched BEFORE file serving takes place. If placed
// after as shown here then file serving is performed BEFORE
// any routes are hit:
app.use(app.router);
