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!

The ReactiveX library

The Rx library is a cross-platform library that uses the observer pattern to help developers manage asynchronous data changes over time. Simply put, ReactiveX is a library that allows us to create and manipulate Observable objects. In Angular 2 projects, we use the RxJS library, which is basically a JavaScript version of the ReactiveX library. If you look closely at the previous chapter, you'll be able to see that we already set it up and even used it in our authentication service. We did that by installing it using npm:

"rxjs": "5.0.0-beta.12",

We imported it in our entities as follows:

import 'rxjs/Rx';

We had to do this because the Angular team chose to use Observables quite extensively. And one of our first encounters with it was using the http client.
