[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

#!/bin/sh

# Install Node.js 14.2.0

sudo su

yum install -y git

curl https://raw.githubusercontent.com/creationix/nvm/v0.35.3/install.sh | bash

source ~/.bashrc

nvm install v14.13.0

# Relevant for some OSes

export NVM_DIR="$HOME/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

For getting a list of all installed nodes, you can use

#!/bin/sh
nvm ls #list all nodes
nvm use <version># switch to specific version
