Clojure Programming Cookbook

Overview of this book

When it comes to learning and using a new language you need an effective guide to be by your side when things get rough. For Clojure developers, these recipes have everything you need to take on everything this language offers. This book is divided into three high impact sections. The first section gives you an introduction to live programming and best practices. We show you how to interact with your connections by manipulating, transforming, and merging collections. You’ll learn how to work with macros, protocols, multi-methods, and transducers. We’ll also teach you how to work with languages such as Java, and Scala. The next section deals with intermediate-level content and enhances your Clojure skills, here we’ll teach you concurrency programming with Clojure for high performance. We will provide you with advanced best practices, tips on Clojure programming, and show you how to work with Clojure while developing applications. In the final section you will learn how to test, deploy and analyze websocket behavior when your app is deployed in the cloud. Finally, we will take you through DevOps. Developing with Clojure has never been easier with these recipes by your side!

Behavior-driven development

Behavior-driven development (BDD) is not a new technique, and there are quite a few blog entries written to present the advantages of some specific library.

This recipe is about using the Cucumber framework in new ways that make the language talk. The primary language you will be using for this recipe will not be Clojure, it will be simple English!!!!!!

You will start by reviewing the basics, and building along some highly interactive patterns to work with Spark, virtual machines, and OpenCV. Let the fun begin...

Getting ready

This Clojure project needs very little to get started. As usual, we add the default dependencies and a Leiningen plugin.


Updating the project.clj file for this recipe will be done while you progress along so, here, let's just get the basics in:

:plugins [[org.clojars.punkisdead/lein-cucumber "1.0.5"]] 
:dependencies [ 
    [org.clojure/clojure "1.9.0-alpha7"] 

Clojure 1.9 is not required, but it may just be the right time to try...
