Setup Node

update apt repository cache

sudo apt update

Using APT

install node.js and npm

sudo apt-get install nodejs npm --no-install-recommends

Using NVM

configure Node.js: Here we find a bash script to manage multiple active node.js versions

node -v
which node
chmod 700 ~/.profile
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
command -v nvm
nvm -v
. ~/.profile
nvm -v
command -v nvm
echo $NVM_DIR

OPTION: log out and log in again so that the configuration is updated
Select and Install a Node.js version

nvm version-remote --lts
nvm ls-remote| grep 'Latest LTS'| grep v18
nvm i <lts>

NOTE: Make sure node.js is available in the correct version

which node

OPTION: Compare nvm's and user's Node.js version

/usr/bin/node -v
node -v

Helpful NVM instructions

install specific node version

nvm install 12.20.1

list installed node versions for the current user

nvm ls

find available node versions for installation

nvm ls-remote

select a different node version for the current session only

nvm use 12.20.1

find the default version for the current user

nvm run default --version

run node script with the desired node version

nvm exec 12.20.1 <node script>.js
