REPL-driven Clojure development builds and validates functions interactively in a REPL session. Start by launching a Clojure REPL, load your namespace, and iteratively define and test functions without restarting. This workflow catches errors early and accelerates feedback cycles during development.

Idiomatic Clojure emphasizes functional programming principles: immutability, pure functions, and data transformation over mutation. Use persistent data structures, leverage sequence operations, apply structural editing to maintain readability, and organize code into namespaces that reflect logical boundaries.

Yes, REPL-driven workflows apply to both Clojure and ClojureScript. ClojureScript REPLs connect to browser or Node.js environments, letting you test code interactively. The same principles of incremental development, testing, and refactoring carry across both languages.

Refactor Clojure code by using structural editing tools and the REPL to validate changes across namespace boundaries. Test refactored functions directly in the REPL, ensure dependencies between namespaces remain sound, and apply functional patterns to keep code modular and composable.

Use clojure-mcp tools to automate REPL-driven tasks—building, testing, and validating functions. These tools enforce best practices and safe fallbacks. If clojure-mcp tools are unavailable, fallback to mage commands to maintain workflow continuity.

Prevent errors through REPL-driven validation before committing code, structural editing to catch syntax issues early, and adherence to functional programming principles that reduce side effects and state mutation. Test incrementally and leverage immutability to avoid hidden state bugs.
