This is the code repository for Hands-On Reactive Programming with Clojure - Second Edition, published by Packt.
Create asynchronous, event-based, and concurrent applications
Reactive Programming is central to many concurrent systems, and can help make the process of developing highly concurrent, event-driven, and asynchronous applications simpler and less error-prone.
This book covers the following exciting features:
- Understand how to think in terms of time-varying values and event streams
- Create, compose, and transform observable sequences using Reactive extensions
- Build a CES framework from scratch using core.async as its foundation
- Develop a simple ClojureScript game using Reagi
- Integrate Om and RxJS in a web application
- Implement a reactive API in Amazon Web Services (AWS)
- Discover helpful approaches to backpressure and error handling
- Get to grips with futures and their applications

All of the code is organized into folders. For example, Chapter02.
The code will look like the following:
(fn [ctx val]
(-> ctx
canvas/save
(canvas/translate (:x val) (:y val))
Following is what you need for this book: If you’re interested in using Reactive Programming to build asynchronous and concurrent applications, this is the book for you. Basic knowledge of Clojure programming is necessary to understand the concepts covered in this book.
With the following software and hardware list you can run all code files present in the book (Chapter 1-12, Appendix).

Konrad Szydlo has worked with Clojure for the last 7 years. Since January 2016, he has worked as a software engineer and team leader at Retailic, responsible for building a website for the biggest royalty program in Poland. Prior to this, he worked as a developer with Sky, developing e-commerce and sports applications, where he used Ruby, Java, and PHP. He is also listed in the Top 75 Datomic developers on GitHub.
Konrad is a part of the Clojurian Slack community, is very interested in functional programming, and gave a Datomic Database talk at the ClojureD conference in Berlin in 2015. He also gave a talk on Creating reactive components using ClojureScript React wrappers during Lambda Days in Kraków in 2016.
Leonardo Borges is a programming languages enthusiast who loves writing code, contributing to open source software, and speaking on subjects he feels strongly about. He has used Clojure professionally, both as a lead consultant at ThoughtWorks and as a development team lead at Atlassian, where he helped build real-time collaborative editing technology.
Leonardo is currently the CTO for MODRON. Apart from this book, he contributed a couple of chapters to Clojure Cookbook, O'Reilly.
Leonardo founded and currently runs the Sydney Clojure User Group in Australia. He also writes posts about software, with a focus on functional programming, on his website. When he isn't writing code, he enjoys riding motorcycles, weightlifting, and playing the guitar.
