Node-red with plesk / node.js

Hi there,

I want to install Node-red on my hosted server with Alfahosting. It is a Debian Server, that has Node.js via Plesk already installed. Sadly, the information found on Plesk-docs etc. don´t list any Node-red installation instructions. Does, by any chance, anyone of you have experience using this combination?
I do have all access to the server. It is an SSL protected domain via Let´sEncrypt.

Any help appreciated!

Regards,
Jürgen
