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.

Fetching and Displaying Data

In the previous chapter, we created a new WorldCities solution containing a WorldCities project (our Angular app) and a WorldCitiesAPI project (our ASP.NET Web API) and made a considerable effort to empower the latter with a DBMS-based data provider, built upon Entity Framework Core using the Code-First approach. Now that we have data persistence, we’re ready to entrust our users with the ability to interact with our application; this means that we can switch to the Angular app and implement some much-needed stuff, such as the following:

  • Fetching data: Querying the data provider from the client side using HTTP requests and getting structured results back from the server side
  • Displaying data: Populating typical client-side components such as tables and lists, and thereby ensuring a good user experience for the end user
  • Adding countries to the loop: For the sake of simplicity, we’ll learn how to implement the fetch and...
