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.

Backend chat service

So far, we've only scratched the surface of our backend application. We are going to add a service layer to our server. This abstraction layer will implement all the business logic, such as instant messaging. The service layer will handle interaction with other application modules and layers.

As for the WebSockets part of the application, we are going to use socketIO, which is a real-time communication engine. They have a really neat chat application example. If you haven't heard of it, you can take a look at the following link:

Chat service implementation

Now that we are familiar with socketIO, we can continue and implement our chat service. We are going to start by creating a new file called app/services/chat/index.js. This will be the main file for our chat service. Add the following code:

'use strict';

const socketIO = require('');
const InstantMessagingModule = require('./instant-messaging.module');

module.exports = build...
