Hello, I am pretty new to this, I have a node.js droplet and I am trying to view my app as I would do in local development (i.e : node app.js). I tried to find info on how to do it but uncessfully.

I have my super admin user, I have the right permissions to my var/www folder... I cmd to the folder and try running the cmd : node app.js and then navigate to my registered domain and no results...

anyone has a clue for me I'm really confused.
