Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a web browser. This course is your guide for learning the fundamentals of Node.js.

In this course, you'll start by understanding the inner workings of Node.js. More specifically, you’ll explore its features, how event loops work, and how multithreading works. You’ll then move on to the fundamentals of Node.js like file systems, global objects, and the Buffer class.

In the latter half of the course, you’ll explore more advanced concepts like modules,  events,  and packages. At the end of this course, you will get hands-on with Node.js and create your own food delivery web application.

By the end of this course, you will have a new, in-demand skill to put on your resume and a cool project to add to your portfolio.

# Packages in Node.js
Node.js packages allow us to reuse code that has already been written by other people. This concept is not something that is unique to Node.js; Python and its package installer, pip, accomplish what Node.js does with npm. So what exactly is a package?
 

Here are some famous packages:
- [React](https://reactjs.org/) is a JavaScript library that allows us to create interactive user interfaces.
- [Express](https://expressjs.com/) is a minimal Node.js web application framework that provides a robust set of features for web and mobile applications.
- [Axios](https://github.com/axios/axios) is a promise-based HTTP client for the browser and Node.js. 


A package must contain a `package.json` file in order to be published to the npm registry. Since modules are not required to have a `package.json` file, not all modules are packages. Only modules that have a `package.json` file are packages.

# npm
**npm** is the package manager for Node.js; it is a software registry that makes sharing and accessing packages easy. npm is installed when Node.js is installed. Each project has dependencies that are listed in its package.json. The dependencies can be installed using a single line. The [website](https://www.npmjs.com/) makes searching for packages very easy. Packages can then be installed from the npm #key# CLI: Command Line Interface #key#. Try installing React in the terminal below. Use the command `npm install react`.
