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).

A peek into the things we haven't covered yet


The Rx programming model can be considered as confluence of the following:

  • Data-flow computation
  • Declarative concurrency
  • Functional programming
  • Stream processing (event)
  • Design patterns and idioms

To get a comprehensive view of the whole discipline, you need to work with the programming model extensively. Initially, things won't make much sense. At some point, you'll reach a click point where everything will start making sense. So far, we have covered the following topics:

  • Observables and Observers
  • Basic and intermediate Operators
  • Basic and intermediate scheduling

This is just the beginning, and we need to cover many more topics to get familiar with the programming model. They are:

  • Hot and cold Observables (Chapter 8RxCpp - the Key Elements)
  • A detailed exploration of Rx components (Chapter 8RxCpp - the Key Elements)
  • Advanced scheduling (Chapter 8,RxCpp - the Key Elements)
  • Programming GUI systems (Chapter 9Reactive GUI Programming Using Qt/C++)
  • Advanced...
