ZoneOS platform servers default to the latest Node.js LTS (Long-term support) version. At the time of updating this article, it is version 20.12.1.
If you want to use another version of Node (older or newer), you will have to install the desired version on the virtual server itself.
In order to install, connect to the server via SSH. Learn more:
To install a specific version of Node, first install the Node version manager nvm on the server.
To do this, enter the command:
