This book will help you learn how to implement the reactive programming paradigm with C++ for building asynchronous and concurrent applications. The reactive programming model requires tremendous amount of pre-requisites in terms of proficiency in programming models (OOP/FP), event-driven GUI programming, language-level concurrency, lock free programming , design Patterns, and event stream programming. The first six chapters cover the these topics in a detailed manner. For the remaining chapters, we have based our discussions on industrial-strength RxCpp library. The topics covered include introduction to the RxCpp programming model, five key elements of the RxCpp programming model, GUI programming using Qt, writing custom operators, Rx design patterns, reactive microservices, and advanced exceptions/operators. By the end of the book, you will be able to confidently embed Rx constructs in your programs to write better concurrent and parallel applications using C++.

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).
