    Description:

    Node.js makes it possible to write applications in JavaScript on the server. It’s built on the V8 JavaScript runtime and written in C++—so it’s fast. Originally, it was intended as a server environment for applications, but developers started using it to create tools to aid them in local task automation. Since then, a whole new ecosystem of Node-based tools (such as Grunt, Gulp and webpack) has evolved to transform the face of front-end development.

    To make use of these tools (or packages) in Node.js we need to be able to install and manage them in a useful way. This is where npm, the Node package manager, comes in. It installs the packages you want to use and provides a useful interface for working with them.

    In this tutorial, I’m going to look at the basics of working with npm. I’ll show you how to install packages in local and global mode, as well as delete, update and install a certain version of a package. I’ll also show you how to work with package.json to manage a project’s dependencies.
