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.

Summary

This chapter was all about reading data from the ASP.NET back-end and finding a way to properly show it to the browser with the Angular front-end.

We started by using our existing CitiesController to fetch a large number of cities with Angular components; although both frameworks are perfectly able to deal with massive data, we quickly understood that we need to improve the whole data request, response, and render flow process to grant our users a decent user experience.

For this very reason, we chose to adopt the System.Linq.Dynamic.Core .NET package to revamp our server-side business logic and the Angular Material npm package to greatly improve our client-side UI. By combining the powerful features of these two packages, we managed to pull off a bunch of interesting features: paging, sorting, and filtering. During our development journey, we also took the chance to identify, address, and mitigate some important security issues, such as a harmful SQL injection risk...
