Install nodejs from nodejs.org

WAIT

use NVM to install only into your user $HOME

You don’t want NodeJS installed system-wide. ( if your machine is not a dedicated server )

apt install curl -y 
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
# Install the version of NodeJS You wish to use 
nvm install node # for the lastest non-long-term Version 
nvm install --lts # for the long-term-Support Version

  • Node is the V8 Engine that uses JavaScript for Servers

  • Have different options since it runs on server not in browser. ( there is no DOM object )

  • We can use nodejs to speed up developing using the coc plugin with vim.

  • We use nodejs to build server-side websites ( back-end )

  • We use nodejs to build Desktop, iOS and Android applications ( using Frameworks like React-Native )

  • Nodejs comes with npm which is used to install new packages

Normally, all configurations needed to access any script, is written in $HOME/.bashrc, but if not, just add this lines to the end of your $home/.bashrc file

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Open new terminal or just ensure everything is working

source .bashrc

If You wish to use NodeJS Modules to develop or to make your Editor, responsive, as user, you can do it like:

npm i -g eslint live-server
npm i -g typescript

Start developing:

cd code/project 
live-server
