Let’s Understand What is NPM?
Node Package Manager or NPM is the only default and official package manager utilized for installing Node JS on a computer system.
In addition, it offers a command-line interface to access and utilize packages during software development, and all the packages are defined under a default file, known as package.json. It also aids the users in managing multiple dependencies from a single CLI.
It is downloaded and installed simultaneously with Node JS on your system, which means that you don’t require any additional or different files to install NPM and Node JS on your system.
Below is snippet displays how web developers are leveraged from NPM CLI to install and utilize relevant packages in their applications.
Moreover, Website, Command Line Interface, and Registry are the three main components of the Node Package Manager.
