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 xUnit.net (.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’ll talk about ASP.NET Core SignalR, an open-source library that allows us to add real-time functionality to web applications by enabling server-side code to push content to clients instantly.

Such a requirement might have little or no use in most general-purpose apps, including the WorldCities app we’ve been working on since Chapter 5, Data Model with Entity Framework Core; however, it can be very useful for some specific scenarios, such as:

  • Online games, especially if they need to support multiple players acting simultaneously in a common or shared environment
  • Social networks, assuming they need some kind of notification system
  • Collaborative apps such as blogs, CMSes, whiteboards, team meetings, file-sharing services, and the like
  • Dashboard and monitoring apps, including our HealthCheck app

As we can easily guess, the HealthCheck app will be the perfect candidate to explore...
