How can you install Node.js on the Astra Linux operating system?

To install Node.js on Astra Linux, you can use several approaches:

1. Using the apt package manager (if Node.js is available in Astra Linux repositories):

sudo apt update
sudo apt install nodejs npm

2. Installing via Node Version Manager (nvm):

• Install nvm:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.4/install.sh | bash
source ~/.bashrc

• Install the desired Node.js version:

nvm install node
nvm use node

3. Downloading official binary files from the Node.js website:

• Go to https://nodejs.org/en/download/
• Download the archive for Linux
• Extract and add to PATH

Using nvm is preferable as it allows easy management of Node.js versions without conflicts with system packages.
