Angular 6 for Enterprise-Ready Web Applications

By: Doguhan Uluca

Overview of this book

Angular 6 for Enterprise-Ready Web Applications follows a hands-on and minimalist approach demonstrating how to design and architect high quality apps. The first part of the book is about mastering the Angular platform using foundational technologies. You will use the Kanban method to focus on value delivery, communicate design ideas with mock-up tools and build great looking apps with Angular Material. You will become comfortable using CLI tools, understand reactive programming with RxJS, and deploy to the cloud using Docker. The second part of the book will introduce you to the router-first architecture, a seven-step approach to designing and developing mid-to-large line-of-business applications, along with popular recipes. You will learn how to design a solid authentication and authorization experience; explore unit testing, early integration with backend APIs using Swagger and continuous integration using CircleCI. In the concluding chapters, you will provision a highly available cloud infrastructure on AWS and then use Google Analytics to capture user behavior. 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.

Role-based routing after login

This is the most elemental and important part of your application. With lazy loading, we have ensured only the bare minimum amount of assets will be loaded to enable a user to login.

Once a user logs in, they should be routed to the appropriate landing screen as per their user role, so they're not guessing how they need to use the app. For example, a cashier needs to only access the POS to check out customers, so they can automatically be routed to that screen.

You find the mock up of the POS screen as illustrated:

Let's ensure that users get routed to the appropriate page after logging in by updating the LoginComponent:
  1. Update the login logic to route per role:
app/src/login/login.component.ts  

async login(submittedForm: FormGroup) {
...
this.router.navigate([
this.redirectUrl || this.homeRoutePerRole...
