Reactive Programming for .NET Developers

Overview of this book

Reactive programming is an innovative programming paradigm focused on time-based problem solving. It makes your programs better-performing, easier to scale, and more reliable. Want to create fast-running applications to handle complex logics and huge datasets for financial and big-data challenges? Then you have picked up the right book! Starting with the principles of reactive programming and unveiling the power of the pull-programming world, this book is your one-stop solution to get a deep practical understanding of reactive programming techniques. You will gradually learn all about reactive extensions, programming, testing, and debugging observable sequence, and integrating events from CLR data-at-rest or events. Finally, you will dive into advanced techniques such as manipulating time in data-flow, customizing operators and providers, and exploring functional reactive programming. By the end of the book, you'll know how to apply reactive programming to solve complex problems and build efficient programs with reactive user interfaces.

Functional Reactive Programming

FRP, the central theme of the second half of the chapter, may be considered by definition as a programming paradigm. In fact, this paradigm is different from the more common ones, such as imperative, object-oriented and functional, because it applies only to Reactive Programming. The context of use is much smaller.

In the previous chapters, we understood how the library Rx represents all these data sequences as observable sequences and how it can be used to compose asynchronous and event-based programs.

Similarly, we will now introduce FRP exploiting objects and, in general, all the features of F# and functional programming. This is possible due to the inherent ability of the language to make almost every instruction in a function block.

In the following sections, we will see in detail the following points:

  • What is FRP and how can you represent it?

  • What are the main features and applicable scenarios?

  • The concept of asynchronous data flow

  • The types on push-based and...
