Changing the Node.js version

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:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

After installing nvm, you must disconnect from the server for a short time, then reconnect to the server. To disconnect, type exit at the command prompt or press Ctrl+D.

After reconnecting to the server, it is possible to use the nvm command.

You can check the version of Node.js currently running on the server with the command node -v

virtXXXXX:sn-69-51.tll07.zoneas.eu:~> node -v
v20.12.1

If you want to install the latest available version of Node.js on the server, enter:
nvm install node

To install a specific version of Node.js, enter a command in the form:
nvm install 18.13.0

virtXXXXX:sn-69-51.tll07.zoneas.eu:~> nvm install 18.13.0
