Overview of this book

Every full-stack ninja needs the tools to operate on front-end and back-end application development. This web app development book takes a hands-on, project-based approach to provide you with all the tools and techniques that web developers need to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. The fifth edition has been updated to cover advanced topics such as Minimal APIs, Web APIs with GraphQL, real-time updates with SignalR, and new features in .NET 6 and Angular 13. You begin by building a data model with Entity Framework Core, alongside utilizing the Entity Core Fluent API and EntityTypeConfiguration class. You'll learn how to fetch and display data and handle user input with Angular reactive forms and front-end and back-end validators for maximum effect. Later, you will perform advanced debugging and explore the unit testing features provided by (.NET 6) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications, learning about their technical requirements, testing processes, and how to convert a standard web application to a PWA. By the end of this web development book, you will understand how to tie together the front-end and back-end to build and deploy secure and robust web applications.

In this chapter, we have spent some valuable time consolidating the existing source code of our WorldCities Angular app. We successfully implemented some optimizations and tweaks by making good use of the TypeScript class inheritance features, and we learned how to create base classes (superclasses) and derived classes (subclasses), thus making our source code more maintainable and DRY. At the same time, we took the chance to perform some bug fixing and add a couple of new features to our app’s UI.

Right after that, we refined the data fetching capabilities of our Angular app by switching from direct usage of Angular’s HttpClient class in our components to a more versatile service-based approach. Eventually, we created CityService and CountryService – both extending a BaseService abstract class – to deal with all the HTTP requests, thus paving the way for post-processing, error handling, retry logic, and more interesting stuff that will be introduced...
