Greetings!

There are several ways to go about this. The dirtiest way (in my opinion) is simple but not fault tolerant, and it uses a screen session. So, for example, if this were Debian/Ubuntu:

apt-get update
apt-get install screen -y
screen -S nodeapp
node app.js

Then CTRL+A followed by CTRL+D to detach from the screen session. This persists when you log out of your SSH session.

However, I recommend something a bit more powerful if you’re up for it. You can use PM2 as a manager for this, and we have a tutorial here:

https://www.digitalocean.com/community/tutorials/how-to-use-pm2-to-setup-a-node-js-production-environment-on-an-ubuntu-vps

Obviously you don’t need all of that tutorial, but you should be able to extract what is relevant to you.
