How can I point upper folder when using express.static() in Express 4.0?

Question

My angular & node app structure is like this.

MyApp/
----app/
--------components/
-----------angular js files(js,css)
----server/
--------server.js
----index.html

And I want to use express.static() to set static files such as angular.js files or css files. but, I'm not sure how to point to upper folder when using static(__dirname +'/app') .

__dirname means current directory but I want to point upper directory.

How about:

var path = require('path');
var dir = path.normalize(__dirname +'/../app');

from the documentation :

Normalize a string path, taking care of '..' and '.' parts.

When multiple slashes are found, they're replaced by a single one; when the path contains a trailing slash, it is preserved. On Windows backslashes are used.
