Developers are discovering the immense power of Clojure's functional programming model to quickly solve problems in domains ranging from social networking to Big Data. Targeting the Java Virtual Machine, Clojure also leverages the Java platform's maturity and enormous ecosystem. Clojure Recipes is a "code recipe book" for this increasingly popular language.
Julian Gamble focuses on practical and complete examples that illuminate Clojure's key features and show step-by-step how to solve real-world problems with it. Clojure Recipes provides a series of "learn by doing" step-by-step projects, you'll learn how to:
- Write your own DSL
- Build a website with Pedestal
- Add Clojurescript to your website
- Abstract boilerplate code into a macro
- Get started with Storm
- Get started with Datomic
- Build log readers, web app monitors, web testing suites, customized Ant tasks, and more
