Clojure Frameworks and Libraries for Java Developers

Clojure framework work should make JVM applications smaller and more explicit, not merely replace Java framework names with Clojure library names. This track focuses on practical web, async, interop, build, testing, deployment, and enterprise integration decisions.

Read the chapters as a framework decision map. Each section should help you choose the smallest useful abstraction, keep data flow visible, and build Clojure services that remain understandable in production.
