By: Doguhan Uluca

Overview of this book

This second edition of Angular for Enterprise-Ready Web Applications is updated with in-depth coverage of the evergreen Angular platform. You’ll start by mastering Angular programming fundamentals. Using the Kanban method and GitHub tools, you’ll build great-looking apps with Angular Material and also leverage reactive programming patterns with RxJS, discover the flux pattern with NgRx, become familiar with automated testing, utilize continuous integration using CircleCI, and deploy your app to the cloud using Vercel Now and GCloud. You will then learn how to design and develop line-of-business apps using router-first architecture with observable data anchors, demonstrated through oft-used recipes like master/detail views, and data tables with pagination and forms. Next, you’ll discover robust authentication and authorization design demonstrated via integration with Firebase, API documentation using Swagger, and API implementation using the MEAN stack. Finally, you will learn about DevOps using Docker, build a highly available cloud infrastructure on AWS, capture user behavior with Google Analytics, and perform load testing. By the end of the book, you’ll be familiar with the entire gamut of modern web development and full-stack architecture, learning patterns and practices to be successful as an individual developer on the web or as a team in the enterprise.

Dynamic UI components and navigation

AuthService provides asynchronous auth status and user information, including a user's name and role. We can use all this information to create a friendly and personalized experience for users. In this next section, we will implement the LoginComponent so that users can enter their username and password information and attempt a login.

Implementing the login component

The login component leverages the AuthService that we just created and implements validation errors using reactive forms.

Remember that in app.module.ts we provided AuthService using the class InMemoryAuthService. So, during run time, when AuthService is injected into the login component, the in-memory service will be the one in use.

The login component should be designed to be rendered independently of any other component, because during a routing event, if we discover that the user is not properly authenticated or authorized, we will navigate them...
