ASP.NET Core 5 and Angular - Fourth Edition

By: Valerio De Sanctis

Overview of this book

Learning full-stack development calls for knowledge of both front-end and back-end web development. ASP.NET Core 5 and Angular, Fourth Edition will enhance your ability to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. This revised edition includes coverage of the Angular routing module, expanded discussion on the Angular CLI, and detailed instructions for deploying apps on Azure, as well as both Windows and Linux. Taking care to explain and challenge design choices made throughout the text, Valerio teaches you how to build 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 xUnit.net (.NET 5) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications (PWAs), learning about their technical requirements, testing, and converting SWAs to PWAs. By the end of this book, you will understand how to tie together the front end and back end to build and deploy secure and robust web applications.

Optimizations and tweaks

In computer programming, the term code bloat is commonly used to describe an unnecessarily long, slow, or wasteful amount of source code. Such code is hardly desirable because it inevitably makes our app more vulnerable to human errors, 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 previously mentioned 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 5, 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...
