Overview of this book

The MEAN stack is a collection of the most popular modern tools for web development that helps you build fast, robust, and maintainable web applications. Starting with the MEAN core frameworks, this pragmatic guide will explain the key concepts of each framework, how to set them up properly, and how to use popular modules to connect it all together. By following the real-world examples shown in this tutorial, you will scaffold your MEAN application architecture, add an authentication layer, and develop an MVC structure to support your project development. You will learn the best practices of maintaining clear and simple code and will see how to avoid common pitfalls. Finally, you will walk through the different tools and frameworks that will help expedite your daily development cycles. Watch how your application development grows by learning from the only guide that is solely orientated towards building a full, end-to-end, real-time application using the MEAN stack!

Introducing WebSockets

Modern web applications, such as Facebook, Twitter, and Gmail, are incorporating real-time capabilities which enable applications to continuously present the user with recently updated information. Unlike traditional applications, in real-time applications, the common roles of the browser and the server can be reversed since the server needs to update the browser with new data regardless of the browser request state. This means that unlike the common HTTP behavior, the server won't wait for the browser's requests. Instead, it will send new data to the browser whenever this data becomes available.

The first and easiest way is XMLHttpRequest (XHR) polling. In XHR...
