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!

Developing with, the next-generation ClojureScript library

In this recipe, we will learn David Nolen's om to build a ClojureScript application. Om is a ClojureScript library to interact with React. React is a very famous JavaScript library developed by Facebook. React enables developments of user interfaces simpler and reusable UI components.

Recently, Nolen started to develop It's a successor of om and inspired by Facebook's Relay, Netflix's Falcor, and Cognitect's Datomic. It is still alpha but it is worth digging it. The project.clj of is as follows:

Getting ready

Before learning, we will create and set up a new project named om-next-example.

Creating a new project for

To create a new project for, issue the following command:

$ lein new figwheel om-next-example -- --om

Updating the om version

Go to the om-next-example directory and update the om version in your project.clj to enable
