Setting up two different static directories in node.js Express framework

Question

Is it possible? I would like to set up two different directories to serve static files. Let\'s say /public and /mnt

Answer 1

It's not possible by one middleware injection, but you can inject static middleware multiple times:

app.configure('development', function(){
    app.use(express.static(__dirname + '/public1'));
    app.use(express.static(__dirname + '/public2'));
});

Explanation

Look at connect/lib/middleware/static.js#143:

path = normalize(join(root, path));

There is options.root is static root, which you define in express.static or connect.static call, and path is request path.

Look more at connect/lib/middleware/static.js#154:

  fs.stat(path, function(err, stat){
    // ignore ENOENT
    if (err) {
      if (fn) return fn(err);
     return ('ENOENT' == err.code || 'ENAMETOOLONG' == err.code)
       ? next()
       : next(err);

Path checked only once, and if file not found request passed to next middleware.

Update for Connect 2.x

Links to code are inactual for Connect 2.x, but multiple static middleware usage are still posible as before.
