Node.js is an open-source cross-platform JavaScript run-time environment that allows server-side execution of JavaScript code which simply means that you can run JavaScript code on your machine as a standalone application, free of any web browser.

The Node.js framework is available for a variety of operating systems right from Windows to Ubuntu and OS X. Once the Node.js framework is installed, you can start building your first Node.js applications. Node.js also has the ability to embed external functionality or extended functionality by making use of custom modules.

node --version

NPM doesn’t ship with Node so you’ll need to separately install it. Run the following command:

sudo apt install npm
  • Install Node.js using NVM.

Visit the nvm GitHub repository page and install the nvm script:

curl -o- | bash

The script will clone the project’s repository from Github to the ~/.nvm directory, Once the script, is in your PATH, verify that nvm was properly installed by typing:

nvm --version

To install the latest available version of Node.js, run:

nvm install node

Check the version of Node.js and NPM using the following command:

node --version
