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.

To overcome these limitations, we decided to provide ourselves with a DBMS engine and a persistent database for reading and/or writing data. To avoid messing with what we did in the previous chapters, we created a brand-new web application project to deal with that, which we called WorldCities.

Then, we chose a suitable data source for our new project: a list of world cities and countries that we could download for free in a handy MS Excel file.

Right after that, we moved on to the data model: Entity Framework Core seemed an obvious choice to get what we wanted, so we added its relevant packages to our project. We briefly enumerated the available data modeling approaches and resorted to using Code-First due to its flexibility.

Once done, we created our two entities, City and Country, both of which are based on the data source values we had to store...
