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.

Custom data types

In order to group similar functionalities and have custom type checking, we are going to define classes for each entity used in our application. This will give us access to custom initialization and default values when creating entities.

User type

Our first custom data type used in the frontend Angular application will be a user. You can use an interface to define a custom type or a regular class. If you need default values or custom validation, go with a regular class definition.

Create a new file called public/src/datatypes/user.ts and add the following class:

export class User {
  _id: string;
  email: string;
  name: string;
  avatar: string;
  createdAt: string;

  constructor(_id?: string, email?: string, name?: string, createdAt?: string) {
    this._id = _id; = email; = name;
    this.avatar = '{{hash}}?s=50&r=g&d=retro'.replace('{{hash}}', _id);
    this.createdAt = createdAt;
