ASP.NET Core 5 and React - Second Edition

By: Carl Rippon

Overview of this book

Microsoft’s .NET framework is a robust server-side framework, now even more powerful thanks to the recent unification of the Microsoft ecosystem with the .NET 5 framework. This updated second edition addresses these changes in the .NET framework and the latest release of React. The book starts by taking you through React and TypeScript components for building an intuitive single-page application and then shows you how to design scalable REST APIs that can integrate with a React-based frontend. Next, you’ll get to grips with the latest features, popular patterns, and tools available in the React ecosystem, including function-based components, React Router, and Redux. As you progress through the chapters, you'll learn how to use React with TypeScript to make the frontend robust and maintainable and cover key ASP.NET 5 features such as API controllers, attribute routing, and model binding to build a sturdy backend. In addition to this, you’ll explore API security with ASP.NET 5 identity and authorization policies and write reliable unit tests using both .NET and React, before deploying your app on Azure. By the end of this book, you’ll have gained the knowledge you need to enhance your C# and JavaScript skills and build full-stack, production-ready applications with ASP.NET 5 and React.

Reading data using Dapper

In this section, we are going to write some C# code that reads data from the database.

We are going to use the popular repository design pattern to structure our data access code. This will allow us to provide a nice, centralized abstraction of the data layer.

We are going to start by creating a data repository class that will hold all of the queries we are going to make to the data. We are going to create C# classes that hold the data we get from the database, called models.

We will implement methods for getting all the questions, getting questions from a search, getting unanswered questions, getting a single question, getting information stating whether a question exists, and getting an answer.

Creating the repository class

Let's create a class that will hold all of the methods for interacting with the database:
