Nodejs Application Production (Ubuntu) Deployment

[Guy Dillen]

Hello,

I already surfed the Web searching for info about nodejs application to (Ubuntu) production deployment. Especially the folder/directory where to store applications gives different answers, however these /opt /srv/www and /var/www regularly show up. 

My question:

- are all these options  "best practices" or which one is the most used/recommended for 'hosting' both nodejs web applications as well as nodejs "console applications" daemon-services applications?

Thanks.
Guy
