Calva is a Visual Studio Code extension providing a REPL-powered IDE for Clojure and ClojureScript development. It bundles inline evaluation, structural (Paredit) editing, formatting, linting via clj-kondo, a debugger, test running, and refactoring, powered by cider-nrepl and clojure-lsp.

Use cases

  • set up a Clojure development environment in VS Code
  • evaluate Clojure code inline from the editor
  • connect to a project REPL with jack-in
  • structurally edit Lisp code with Paredit
  • run Clojure tests from the editor
  • lint Clojure code with clj-kondo
  • debug Clojure and ClojureScript programs

When to choose

  • you use VS Code and want a full-featured Clojure/ClojureScript IDE
  • you are new to Clojure and want an easy on-ramp with REPL-driven development
  • you want integrated evaluation, Paredit, formatting, and linting without configuring separate tools

When to avoid

  • you use Emacs and prefer CIDER
  • you develop Clojure in IntelliJ with Cursive
  • you need an IDE for languages other than Clojure/ClojureScript
