Preface

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++.
