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.

Nonetheless, we should definitely spend a reasonable amount of time doing that now, because it would be a great way to plant everything we have learned so far in our muscle memory.

Let's do this now so that we can move on to trying something else. To avoid wasting pages, we'll just focus on the most relevant steps here, leaving everything else to what we just did with the cities – and to our GitHub repository, which hosts the full source code of what we need to do.
