Overview of this book

In this book, we will show you how to implement a series of best practices and design patterns to help you create efficient and robust Node.js applications with ease. We kick off by exploring the basics of Node.js, analyzing its asynchronous event driven architecture and its fundamental design patterns. We then show you how to build asynchronous control flow patterns with callbacks, promises and async/await. Next, we dive into Node.js streams, unveiling their power and showing you how to use them at their full capacity. Following streams is an analysis of different creational, structural, and behavioral design patterns that take full advantage of JavaScript and Node.js. Lastly, the book dives into more advanced concepts such as Universal JavaScript, scalability and messaging patterns to help you build enterprise-grade distributed applications. Throughout the book, you’ll see Node.js in action with the help of several real-life examples leveraging technologies such as LevelDB, Redis, RabbitMQ, ZeroMQ, and many others. They will be used to demonstrate a pattern or technique, but they will also give you a great introduction to the Node.js ecosystem and its set of solutions.

Summary

In this chapter, we have shed some light on Node.js streams and some of their most common use cases. We learned why streams are so acclaimed by the Node.js community and we mastered their basic functionality, enabling us to discover more and navigate comfortably in this new world. We analyzed some advanced patterns and started to understand how to connect streams in different configurations, grasping the importance of interoperability, which is what makes streams so versatile and powerful.

If we can't do something with one stream, we can probably do it by connecting other streams together, and this works great with the one thing per module philosophy. At this point, it should be clear that streams are not just a good to know feature of Node.js; they are an essential part—a crucial pattern to handle binary data, strings, and objects. It's not by chance that we dedicated an entire chapter to them.

In the next few chapters, we will focus on the traditional...
