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!

Using Spyglass and Couchbase to share state between JVMs

Spyglass is a very fast Memcached client to share states between JVMs.

Spyglass is a future complete client to support almost all of the Memcached protocol operations, as well as binary and text protocols. Spyglass supports not only synchronous accesses to Memcached but also asynchronous accesses to it.

We will use a Couchbase Server as a Memcached server and access it using Spyglass.

Getting ready

Installing Couchbase and setting up Memcached takes several steps. We will instruct you how to do them.

Setting up dependencies in project.clj

You need to add the spyglass to your project.clj file to run samples (or any other dependency management you are using):

  [[org.clojure/clojure "1.8.0"] 
   [clojurewerkz/spyglass "1.0.0"]] 

Setting up Couchbase Server as a Memcached server

Couchbase Server is an awesome ultrascale document-oriented NoSQL Server. Couchbase Server can be set up as a Memcached server. We will set up Couchbase...
