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.

The Node.js Platform

Some principles and design patterns literally define the developer experience with the Node.js platform and its ecosystem. The most peculiar one is probably its asynchronous nature, which makes heavy use of asynchronous constructs such as callbacks and promises. In this introductory chapter, we will explore where Node.js gets its asynchronous behavior from. This is not just good-to-know theoretical information: knowing how Node.js works at its core will give you a strong foundation for understanding the reasoning behind more complex topics and patterns that we will cover later in the book.

Another important aspect that characterizes Node.js is its philosophy. Approaching Node.js is, in fact, far more than simply learning a new technology: it's also embracing a culture and a community. You will see how this greatly influences the way we design our applications and components, and the way they interact with those created by the community...
