Chapter 13. Reactive Programming Using RxJS

In the previous chapter, we saw how .NET Reactive Extensions (Rx) aided natural programming in terms of composability, scalability, and responsiveness. We saw how streams enable natural state management with respect to time. Some of the constructs were dealt with in detail as well. More importantly, we saw how reactive constructs could be integrated seamlessly into the MVVM pattern, in terms of achieving data synchronization between View and Model via the View Model layer. Now, in this chapter, we will take a deep dive into the Reactive Extensions for JavaScript (RxJS) library, and look at how to write asynchronous and event-driven programs using observable collections. We will also take a detailed look at some interesting use cases, and their implementations with RxJS, to clearly understand how the RxJS library is leveraged to create concurrent and responsive applications. This will cover the reactive spectrum of web and Windows...
