Functional Reactive Programming

Book Description

Summary

Functional Reactive Programming teaches the concepts and applications of FRP. It offers a careful walk-through of core FRP operations and introduces the concepts and techniques you'll need to use FRP in any language.

About the Technology

Today’s software is shifting to more asynchronous, event-based solutions. For decades, the Observer pattern has been the go-to event infrastructure, but it is known to be bug-prone. Functional reactive programming (FRP) replaces Observer, radically improving the quality of event-based code.

About the Book

Functional Reactive Programming teaches you how FRP works and how to use it. You’ll begin by gaining an understanding of what FRP is and why it’s so powerful. Then, you’ll work through greenfield and legacy code as you learn to apply FRP to practical use cases. You’ll find examples in this book from many application domains using both Java and JavaScript. When you’re finished, you’ll be able to use the FRP approach in the systems you build and spend less time fixing problems.

What’s Inside

  • Think differently about data and events

  • FRP techniques for Java and JavaScript

  • Eliminate Observer one listener at a time

  • Explore Sodium, RxJS, and Kefir.js FRP systems

  • About the Reader

    Readers need intermediate Java or JavaScript skills. No experience with functional programming or FRP required.
