Clojurians Log v2

hello! I'm trying out dirac with shadow-cljs. I've seen some issues about it, and in my own attemps I get stuck at this error:

SEVERE: Unable to bootstrap Dirac ClojureScript REPL:

SEVERE: [NREPLTunnelServer#1 of [NREPLTunnel#1]] Received a bootstrap error from client [WebSocketServerClient#1] :
 {:op :bootstrap-error}

(sorry for the long message, wasn't able to attach it as a code "file" in slack)

I understand if this isn't supported, but wanted to ask if it's possible to get running? 🙂 breakpoints with cljs would be very nice

@saikyun Dirac REPL really doesn’t work with shadow-cljs, but you don’t need Dirac REPL to use other Dirac enhancements

simply use Dirac instead of DevTools and don’t use Dirac’s REPL

@darwin thanks for the quick reply. it's the repl I'm currently most interested in (specifically being able to use breakpoints + the cljs repl).

would it be possible/practical to get the ad-hoc repl working, without caring about what shadow-cljs does?

yes, run another nREPL server (using leingingen for example) and connect to it with Dirac REPL

you will have to keep lein’s project.clj in sync with your shadow-cljs setup

you should keep boths setups separate, so their compilation output does not clash
