✦ Synopsis

If the usual patchwork of web development tools and languages just isn’t cutting it for you, you need Web Development With Clojure. Clojure gives you the rich infrastructure of the JVM with the expressive power of a modern functional language. It combines excellent performance with rapid development—and you can exploit these virtues for web app development. With step-by-step examples, you’ll learn how to harness that power and richness to build modern web applications.
