Babashka is highly compatible with Clojure, so it works with CIDER out of the box. All you need to do is start its bundled nREPL server:
$ bb --nrepl-server
And connect to it afterwards using C-c C-x c j (
Babashka’s nREPL server supports all core nREPL operations, plus code completion, so you’ll get all of CIDER’s basic functionality with it.
|Depending on your CIDER version you might get some warnings about missing Clojure/nREPL versions. You can safely ignore those.|
Starting with CIDER 1.2,
cider-jack-in-clj works with Babashka projects that are using
There are a few differences between Babashka and Clojure that you should keep in mind:
Built-in vars (e.g.
clojure.core/map) don’t have definition location metadata. In practice this means you can’t navigate to their definitions in CIDER.
clojure.java.javadoc/javadoc) REPL utility function is not currently available in Babashka.
