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
