ASP.NET Core 3 and React

By: Carl Rippon

Overview of this book

Microsoft's ASP.NET Core is a robust and high-performing cross-platform web API framework, and Facebook's React uses declarative JavaScript to drive a rich, interactive user experience on the client-side web. Together, they can be used to build full stack apps with enhanced security and scalability at each layer. This book will start by taking you through React and TypeScript components to build an intuitive single-page application. You’ll understand how to design scalable REST APIs that can integrate with a React-based frontend. 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. The book shows how you can use TypeScript along with React to make the frontend robust and maintainable. You’ll then cover important .NET Core features such as API controllers, attribute routing, and model binding to help you build a sturdy backend. Additionally, you’ll explore API security with ASP.NET Core identity and authorization policies, and write reliable unit tests using both .NET Core and React before you deploy your app to the Azure cloud. By the end of the book, you’ll have gained all the knowledge you need to enhance your C# and JavaScript skills and build full stack, production-ready applications with ASP.NET Core and React.

Improving Performance and Scalability

In this chapter, we are going to improve the performance and scalability of our REST API. When we make each improvement, we'll use load testing and performance tools to verify that there has been an improvement.

We'll start by focusing on database calls and how we can reduce the number of calls to improve performance. We'll then move on to requesting less data with data paging. We'll also look at the impact that caching data in memory has on performance.

Then, we'll learn how to make our API controllers and data repository asynchronous. We'll eventually understand whether this makes our REST API more performant or perhaps more scalable.

We'll also learn how the garbage collection process can harm performance and why it's best to let ASP.NET Core handle binding requests to models.

In this chapter, we...
