[DevOps] NodeJS installation script for hot update

Hello, this is script is needed for the hot switch versions of Node.js on machine. You can have two installed different versions of Node.js. For example, it can be v12 and v14.

So is possible to switch on a different version using only one command. Currently, I work only on Linux based (and macOS as a client system) systems and code will be targeted on these systems

# Install Node.js 14.2.0
sudo su
yum install -y git
curl | bash
source ~/.bashrc
nvm install v14.13.0
# Relevant for some OSes
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/" ] && . "$NVM_DIR/" # This loads nvm
For getting a list of all installed nodes, you can use
nvm ls #list all nodes
nvm use <version># switch to specific version
