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.

A brief introduction to React

React is a popular JavaScript library created and maintained by Facebook. React is focused on providing a comprehensive set of functions and tools to build the view layer in web applications. React offers a view abstraction focused on the concept of a component. A component could be a button, a form input, a simple container such as an HTML div, or any other element in your user interface. The idea is that you should be able to construct the user interface of your application by just defining and composing highly reusable components with specific responsibilities.

What makes React different from other view libraries for the web is that it is not bound to the DOM by design. In fact, it provides a high-level abstraction called the virtual DOM (nodejsdp.link/virtual-dom) that fits very well with the web but that can also be used in other contexts, for example, for building mobile apps, modeling 3D environments, or even defining the interaction between...
