CHAPTER 5

Using Events and Child Processes

As you have already seen in this book, Node.js has a robust framework for handling many routines and important tasks. In this chapter you will get a full understanding of a few concepts that you saw in earlier chapters. You will first take an in-depth look at a cornerstone of Node.js, EventEmitters. Regarding these you will see recipes on how to create custom events and add listeners for them, as well as how to create single events. All of this will come together to demonstrate how you can reduce an unending callback nightmare by strategically implementing events in Node.js.

Next, you will unravel the ...
