Much of this site was originally AI-generated in 2024 as an experiment. Since then, Clojure, our editorial workflow, and modern AI capabilities have changed substantially.
For the most idiomatic “design patterns in Clojure” guide right now, please visit softwarepatternslexicon.com/clojure . Suggestions are welcome: info@tokenizer.ca .
Clojure • Patterns • Architecture
Practical design and architecture patterns in idiomatic Clojure. From functional programming and concurrency to macros, components, and data pipelines—learn how to structure real-world systems on the JVM with clear examples and explanations.
Clojure is a modern, functional Lisp on the JVM with immutable data, first-class functions, and a powerful concurrency model. It is an excellent fit for concurrent, parallel, and distributed systems, where correctness and simplicity matter.
ClojurePatterns helps you connect classic design ideas with Clojure’s strengths so you write code that is simple, expressive, and robust.
core.async.map, reduce, transducers, and Specter.component.Patterns built on immutability, pure functions, and composition.
Safe shared state and asynchronous workflows.
