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.

Preface

Marble diagrams


A marble diagram exposes graphically a sequence of observable items in a time fashion.

This simple diagram is the standard de facto of exposing observable sequences when composed with observable operators, such as merge, delay, scan, and so on.

The most practical example is available on http://rxmarbles.com .

A marble diagram showing a merge operation

In the preceding screenshot, we can see two time-based sequences of observable numeric values in the first two lines. The balls are the values. The little vertical lines are the OnCompleted messages that define when a sequence ends its life cycle.

The third line shows the merged observable sequence containing all the values from the first two sequences.

The website offers a great selection of examples regarding the most used reactive operators by using marble diagrams. This is useful to understand the operator job before diving into coding.
