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!

Real-time shared development with an REPL

Let's face it, you will spend most of your Clojure time in an REPL, and that satisfaction to get instant feedback from writing code is what will keep you awake at night.

In this recipe, you will see a few REPL astuce, tricks, to make your coding easier and help you create a coding workflow that is your own.

We start with basics on how to use a shared REPL and then build on instant feedback and ideas on writing your custom REPL.

Getting ready

The first part of this recipe will show how to connect using the Atom editor. Make sure you have it installed before, if not, go to


The default settings do not require any additional settings but you will have to add dependencies to the project.clj file as you go reading along.

How to do it...

You will remember how to start a simple REPL with the following:

lein repl

But let's go slightly beyond that and start an REPL that can be shared nicely with others.

For the ultimate DIY sharing...
