First of all You need to install Node.js. On Windows computers go to https://nodejs.org/en/ website, download latest version and install it.
On Linux (Debian, Ubuntu Mint) add PPA repository of Node.js:
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
And install nodejs package
sudo apt-get install nodejs
To check Node.js version use command:
node -v v12.18.3
Now let’s create new application. We will use Visual Studio Code editor. Open terminal and initialize NPM by command:
npm init
This command will create package.json configuration file. This file contains information about all packages, used in application.
