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.

Such code is hardly desirable because it inevitably makes our app more vulnerable to human error, regression bugs, logical inconsistencies, wasted resources, and so on. It also makes debugging and testing a lot more difficult and stressful; for all of the aforementioned reasons, we should try to prevent that from happening as much as we can.

The most effective way to counter code bloat is to adopt and adhere to the Don’t Repeat Yourself (DRY) principle, which is something that any developer should try to follow whenever they can. As already stated in Chapter 6, Fetching and Displaying Data, DRY is a widely achieved principle of software development: whenever we violate it, we fall into a WET approach, which could mean Write Everything Twice, We Enjoy Typing, or Waste Everyone’s Time, depending on what we...
