Node.js the Right Way

Chapter 4Robust Messaging Services

When you write Node.js programs, you’ll often use more than just the core libraries. Node’s package manager, npm, offers a rich collection of community-developed modules you can use. In this chapter, you’ll learn how to make the most out of third-party modules.

In particular, we’re going to explore how to write robust messaging services in Node. We saw the beginnings of networked application development last chapter, and now it’s time to take it to the next level. Creating these messaging applications will expose you to the following aspects of Node.js development.

Architecture and Core

Node.js is single-threaded, but you can still take advantage of multiple cores or processors by running more processes. ...
