Overview of this book

The MEAN stack is a combination of the most popular web development frameworks available—MongoDB, Angular, Express, and Node.js used together to offer a powerful and comprehensive full stack web development solution. It is the modern day web dev alternative to the old LAMP stack. It works by allowing AngularJS to handle the front end, and selecting Mongo, Express, and Node to handle the back-end development, which makes increasing sense to forward-thinking web developers. The MEAN stack is great if you want to prototype complex web applications. This book will enable you to build a better foundation for your AngularJS apps. Each chapter covers a complete, single, advanced end-to-end project. You’ll learn how to build complex real-life applications with the MEAN stack and few more advanced projects. You will become familiar with WebSockets and build real-time web applications, as well as create auto-destructing entities. Later, we will combine server-side rendering techniques with a single page application approach. You’ll build a fun project and see how to work with monetary data in Mongo. You will also find out how to a build real-time e-commerce application. By the end of this book, you will be a lot more confident in developing real-time, complex web applications using the MEAN stack.

The core Service Layer

Because our application will have different clients consuming business logic, we are going to add a Service Layer; it will coordinate operations for different use cases. So, we are going to move most of our business logic from controllers to services. Probably, it's too early to see the benefits of this, but as we progress with this chapter, it will make more sense.

One benefit would be that you can simply expose your Service Layer as a RESTful API, or add another client that will render on the server-side templates and display all the necessary information to the user. Regardless of the application's client implementation, you can test the business logic of your application.

The product catalog

The product catalog will contain all the products you want to be shown or simply exist in the system. Each item in the catalog will be stored in MongoDB, in the products collection. We are going to create a ProductCatalog service, which will hold all the business logic for managing...
