C++ Reactive Programming

By: Praseed Pai, Peter Abraham

Overview of this book

Reactive programming is an effective way to build highly responsive applications with an easy-to-maintain code base. This book covers the essential functional reactive concepts that will help you build highly concurrent, event-driven, and asynchronous applications in a simpler and less error-prone way. C++ Reactive Programming begins with a discussion on how event processing was undertaken by different programming systems earlier. After a brisk introduction to modern C++ (C++17), you’ll be taken through language-level concurrency and the lock-free programming model to set the stage for our foray into the Functional Programming model. Following this, you’ll be introduced to RxCpp and its programming model. You’ll be able to gain deep insights into the RxCpp library, which facilitates reactive programming. You’ll learn how to deal with reactive programming using Qt/C++ (for the desktop) and C++ microservices for the Web. By the end of the book, you will be well versed with advanced reactive programming concepts in modern C++ (C++17).

Summary


We have covered a lot of ground in this chapter, inching towards the reactive programming model. We learned about the GoF Observer pattern and understood its shortcomings. Then, we digressed into philosophy to understand the method of looking at the world from a structural, behavioral, and functional perspective. We learned about the GoF Composite/Visitor pattern in the context of modeling an expression tree. We learned how to flatten the hierarchy into a list and navigate them through the Iterator. Finally, we transformed the scheme of things a bit to reach Observables. Normally, Observables work with Streams, but in our case it was a scalar value. In the next chapter, we will learn about event Stream processing to complete our prerequisites for learning reactive programming.
