npm is a software registry that serves over 1.3 million packages. npm is used by open source developers from all around the world to share and borrow code, as well as many businesses. There are three components to npm:
the website
the Command Line Interface (CLI)
the registry
Use the website to discover and download packages, create user profiles, and handle other aspects of your npm experience. You can grant organizations access to public or private components.
The command-line interface (CLI) is how most Node.js developers work with npm.
The registry is a massive public database of JavaScript programs as well as meta-information about them.
