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).

Applied Stream programming using the Streams library


In this section, we will introduce  the topic of Stream programming using the Streams library ,a public domain library written by Jonah Scheinerman. The library is hosted at https://github.com/jscheiny/Streams and  the API documentation is available from http://jscheiny.github.io/Streams/api.html#. An introduction has been given as following  (taken from the library GitHub page):

Note

Streams is a C++ library that provides lazy evaluation and functional-style transformations on data, to ease the use of C++ standard library containers and algorithms. Streams supports many common functional operations such as map, filter, and reduce, as well as various other useful operations such as various set operations (union, intersection, difference), partial sum, and adjacent difference, as well as many others.

We can see that a programmer who is familiar with the standard template library (STL) will clearly be at ease with this library. The STL Containers...
