This virtualhosts snippet will make your nodejs app run on the traditional port 80, so mynodeapp.com:3000 will simply work on mynodeapp.com without adding :3000. it's that simple :) remember to enable apache modules proxy and proxy_http ($ sudo a2enmod proxy && sudo a2enmod proxy_http)

node_apache.apacheconf

<VirtualHost *:80>
     ServerAdmin [email protected]
     ServerName js.io
     ServerAlias js.io

     ProxyRequests off

     <Proxy *>
          Order deny,allow
          Allow from all
     </Proxy>

     <Location />
           ProxyPass http://127.0.0.1:3000/
           ProxyPassReverse http://127.0.0.1:3000/
     </Location>
     DocumentRoot /var/www/
</VirtualHost>

What is this part for ?

<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>

Rename the gist to "node_apache.apacheconf" to get syntax highlighting, and change the indentation to 4 instead of 5, more standard, example here, too bad pull requests are not available in gists.

All done :) Thanks for the feedback.. Sorry for being too late to reply on this...
