Overview of this book

Node.js is a massively popular software platform that lets you use JavaScript to easily create scalable server-side applications. It allows you to create efficient code, enabling a more sustainable way of writing software made of only one language across the full stack, along with extreme levels of reusability, pragmatism, simplicity, and collaboration. Node.js is revolutionizing the web and the way people and companies create their software. In this book, we will take you on a journey across various ideas and components, and the challenges you would commonly encounter while designing and developing software using the Node.js platform. You will also discover the "Node.js way" of dealing with design and coding decisions. The book kicks off by exploring the basics of Node.js describing it's asynchronous single-threaded architecture and the main design patterns. It then shows you how to master the asynchronous control flow patterns,and the stream component and it culminates into a detailed list of Node.js implementations of the most common design patterns as well as some specific design patterns that are exclusive to the Node.js world.Lastly, it dives into more advanced concepts such as Universal Javascript, and scalability' and it's meant to conclude the journey by giving the reader all the necessary concepts to be able to build an enterprise grade application using Node.js.

Summary


We have reached the end of this chapter. Here, we learned the most important messaging and integration patterns and the role they play in the design of distributed systems. We made our acquaintance with the three major types of message exchange patterns: publish/subscribe, pipelines, and request/reply, and we saw how they can be implemented using a peer-to-peer architecture or a message broker. We analyzed their pros and cons, and we saw that by using AMQP and a fully-fledged message broker, we can implement reliable and scalable applications with little developmental effort but at a cost of having one more system to maintain and scale. Also, we saw how ØMQ allows us to build distributed systems where we can have total control over every aspect of the architecture, fine tuning its properties around our very own requirements.

This chapter also closes the book; by now, we should have a tool belt full of patterns and techniques we can go and apply in our projects. We should also have...
