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.

Adding a new city

Before going any further, let’s spend a couple more minutes adding a very useful feature to our CityEditComponent: the chance to add a brand-new City. This is a rather classic requirement of a Detail view with editing capabilities, which can be handled with the same component – as long as we perform some small modifications to enable it to handle a new feature (adding a new city) as well as the existing one (editing an existing city) in a seamless way.

To do that, we’ll have to perform the following steps:

  1. Extend the functionalities of CityEditComponent to make it able to add new cities, as well as editing existing ones
  2. Add a new Add City button to our component’s template file and bind it to a new client-side route
  3. Implement the required functionalities to select a country for the newly added city, which will also be useful in edit mode (it will allow users to change the country for existing cities)
