Pre Installation Steps

Start by updating and upgrading the server packages to the latest version available.

sudo apt update
sudo apt dist-upgrade -y

Install NVM

You can copy the link for the latest NVM installation bash script directly from their official repository. The version available at the time of this article writing is v0.39.1.

Switch to the user on which you need to use Node.js.

sudo su username

Execute the following command to install NVM.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

This command downloads the installation script and runs it.

For the nvm command to be available you need to close the terminal and open again or you can simply execute the following command to make it available in your current session.

source ~/.bashrc
