Overview of this book

<p>If you have been burnt by unreliable JavaScript frameworks before, you will be amazed by the maturity of the Angular platform. Angular enables you to build fast, efficient, and real-world web apps. In this Learning Path, you'll learn Angular and to deliver high-quality and production-grade Angular apps from design to deployment.</p> <p>You will begin by creating a simple fitness app, using the building blocks of Angular, and make your final app, Personal Trainer, by morphing the workout app into a full-fledged personal workout builder and runner with an advanced directive building - the most fundamental and powerful feature of Angular.</p> <p>You will learn the different ways of architecting Angular applications using RxJS, and some of the patterns that are involved in it. Later you’ll be introduced to the router-first architecture, a seven-step approach to designing and developing mid-to-large line-of-business apps, along with popular recipes. By the end of this book, you will be familiar with the scope of web development using Angular, Swagger, and Docker, learning patterns and practices to be successful as an individual developer on the web or as a team in the Enterprise.</p> <p>This Learning Path includes content from the following Packt products:</p> <p><span style="background-color: transparent;">•Angular 6 by Example by Chandermani Arora, Kevin Hennessy&nbsp;</span><br /><span style="background-color: transparent;">•Architecting Angular Applications with Redux, RxJS, and NgRx by Christoffer Noring</span><br /><span style="background-color: transparent;">•Angular 6 for Enterprise-Ready Web Applications by Doguhan Uluca</span></p>

User class and object-oriented programming


So far, we have only worked with interfaces to represent data, and we still want to continue using interfaces when passing data around various components and services. However, there's a need to create a default object to initialize a BehaviorSubject. In Object-oriented Programming (OOP), it makes a lot of sense for the User object to own this functionality instead of a service. So, let's implement a User class to achieve this goal.

Inside the user/user folder, define an IUser interface and a User class provided in UserModule:

src/app/user/user/user.ts
import { Role } from '../../auth/role.enum'

export interface IUser {
  id: string
  email: string
  name: {
    first: string
    middle: string
    last: string
  }
  picture: string
  role: Role
  userStatus: boolean
  dateOfBirth: Date
  address: {
    line1: string
    line2: string
    city: string
    state: string
    zip: string
  }
  phones: IPhone[]
}

export interface IPhone {
  type: string...
