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!

Working with Immutant - reusing infrastructure

Immutant is not your usual Clojure web framework. Immutant allows you to build into existing and robust middleware, WildFly, aka JBoss, and deploy your software in an elegant fashion. In this recipe, you will see how to enhance your ring application with the wide range of services available through the Immutant framework.

While Immutant makes it easy to deploy to WildFly, the development environment is entirely contained and can be done without extra download or installation. Let's have a look!

Getting ready

This first section will probably be totally disappointing; at this stage, we are fully in the domain of Clojure and things work out of the box. Terrible, huh?

Here is the project.clj file, with the full list of libraries required:

(defproject mutant1 "0.1.0-SNAPSHOT" 
  :dependencies [ 
    [org.clojure/clojure "1.8.0"] 
    [org.immutant/immutant "2.1.4"] 
    [ring/ring-devel "1.5.0"]]) 

ring-devel is added to the mix to allow for development...
