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.

In this chapter, we'll focus on a topic that we just briefly mentioned back in Chapter 1, Getting Ready, when we first talked about the different development patterns for web applications available nowadays: Progressive Web Apps (PWAs).

As a matter of fact, both our HealthCheck and WorldCities apps currently stick to the Single-Page Application (SPA) model, at least for the most part; in the following sections, we'll see how we can turn them into PWAs by implementing several well-established capabilities required by such a development approach.

As we learned in Chapter 1, Getting Ready, a PWA is a web application that uses a modern web browser's capabilities to deliver an app-like experience to users. To achieve this, the PWA needs to meet some technical requirements, including (yet not limited to) a Web App Manifest file and a service worker to allow it to work in offline mode and behave just like a mobile app.
