Clara Rules is an expressive, forward-chaining rules engine written in Clojure (and ClojureScript), designed to let developers encapsulate domain logic cleanly and declaratively using rules defined as code rather than domain-specific languages—while supporting Java interoperability. Clara is a forward-chaining rules engine written in Clojure(Script) with Java interoperability. It aims to simplify code with a developer-centric approach to expert systems. Clara is built, tested, and deployed using Leiningen. ClojureScript tests are executed via puppeteer.

Features

  • Define rules seamlessly within Clojure namespaces
  • Declarative rule syntax with clear separation of condition (LHS) and actions (RHS)
  • Supports rich domain modeling through forward-chaining logic
  • Integrates with Java libraries thanks to interoperability
  • Scales well and optimized for performance in production scenarios
  • Avoids complexity of enterprise-grade rule engines while remaining expressive
