I can't serve static by nginx

Question

I have the following nodejs structure which is resides in /home/ubuntu/project directory:

 sever
 site
   |-css
   |  |-styles.css
   |-img
   |  |-sprite.png
   |-js
     |-script.js

I'm trying to serve static assets by nginx, so I wrote the following location:

upstream myapp_upstream {
    server 127.0.0.1:3000;
    keepalive 64;
}

server {
    listen 80;

    server_name www.myapp.com;

    error_page 400 404 500 502 503 504 /50x.html;
    location  /50x.html {
            internal;
            root /usr/share/nginx/www;
    }

    location ~ ^/(images/|img/|javascript/|js/|css/|stylesheets/|flash/|media/|static/|robots.txt|humans.txt|favicon.ico|home/|html|xml) {
        root /home/ubuntu/project/site;
        access_log off;
        expires max;
    }

    location / {
        proxy_redirect off;
        proxy_set_header   X-Real-IP            $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
        proxy_set_header   Host                   $http_host;
        proxy_set_header   X-NginX-Proxy    true;
        proxy_set_header   Connection "";
        proxy_http_version 1.1;
        proxy_pass         http://myapp_upstream;
        proxy_intercept_errors on;
    }
}

But when I try to open up my site in a browser I get failed status on all requested assets. Whet's the problem?

EDIT: My route to css for example is:

http://www.myapp.com/css/styles.css

Well,

Add a / to the root path.

root /usr/share/nginx/www;

should be

root /usr/share/nginx/www/;

Use an alias for the assets like:

alias /home/ubuntu/project/site/; (again, add the last /)

These is a mess for me:

location ~ ^/(images/|img/|javascript/|js/|css/|stylesheets/|flash/|media/|static/|robots.txt|humans.txt|favicon.ico|home/|html|xml)

You should check these http://wiki.nginx.org/NginxHttpCoreModule#location

I dont see these folders images/, javascript/, stylesheets/, flash/, media/, static/ and home/ in your sitemap.

And these both |html|xml are looking for the route /html or /xml not the .html or .xml files.

Then try:

location ~ ^/(robots.txt|humans.txt) {
    alias /home/ubuntu/project/site/;
    access_log off;
    expires max;
}

location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {  //add here all the file extensions needed.
    alias /home/ubuntu/project/site/;
    access_log off;
    expires max;     
}
