Overview of this book

Node.js is a server-side JavaScript platform using an event-driven, non-blocking I/O model allowing users to build fast and scalable data-intensive applications running in real time. This book gives you an excellent starting point, bringing you straight to the heart of developing web applications with Node.js. You will progress from a rudimentary knowledge of JavaScript and server-side development to being able to create, maintain, deploy and test your own Node.js application.You will understand the importance of transitioning to functions that return Promise objects, and the difference between fs, fs/promises and fs-extra. With this book you'll learn how to use the HTTP Server and Client objects, data storage with both SQL and MongoDB databases, real-time applications with Socket.IO, mobile-first theming with Bootstrap, microservice deployment with Docker, authenticating against third-party services using OAuth, and use some well known tools to beef up security of Express 4.16 applications.

Chapter 3. Node.js Modules

Before writing Node.js applications, you must learn about Node.js modules and packages. Modules and packages are the building blocks for breaking down your application into smaller pieces.

In this chapter, we will cover the following topics:

  • Defining a module
  • The CommonJS and ES2015 module specifications
  • Using ES2015/2016/2017 coding practices in Node.js
  • Using the ES6 module format in Node.js code
  • Understanding how Node.js finds modules
  • The npm package management system

So, let's get on with it.
