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

You have reached the end of this chapter. Here, you learned the most important messaging and integration patterns and the role they play in the design of distributed systems. You should now have mastered the three most important types of message exchange patterns: Publish/Subscribe, Task Distribution, and Request/Reply, implemented either on top of a peer-to-peer architecture or using a broker. We analyzed the pros and cons of each pattern and architecture, and we saw that by using a broker (implementing either a message queue or data stream), it's possible to implement reliable and scalable applications with little effort, but at the cost of having one more system to maintain and scale.

You have also learned how ZeroMQ allows you to build distributed systems where you can have total control over every aspect of the architecture, fine tuning its properties around your very own requirements.

Ultimately, both approaches will give you all the tools that you need...
