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.

Handling routes not found

In this section, we'll handle paths that aren't handled by any of the Route components. By following these steps, we'll start by understanding what happens if we put an unhandled path in the browser:

  1. Enter a path that isn't handled in the browser and see what happens:

    Figure 5.2 – Unhandled path

    So, nothing is rendered beneath the header when we browse to a path that isn't handled by a Route component. This makes sense if we think about it.

  2. We'd like to improve the user experience of routes not found and inform the user that this is the case. Let's add the following highlighted route inside the Routes component:
    <Routes>
      <Route path="" element={<HomePage/>} />
      <Route path="search" element={<SearchPage/>} />
      <Route path="ask" element={<AskPage/>} />
      <Route path="signin" element...
