Does anyone know how to connect vim-fireplace to a shadow-cljs repl? I created a shadow-cljs.edn file with the following config, first without dependencies and added them without any success:

{:source-paths ["src"]
 :dependencies [[cider/cider-nrepl "0.18.0"]
                [figwheel "0.5.15"]
                [com.cemerick/piggieback "0.2.2"]
                [org.clojure/tools.nrepl "0.2.13"]]
 :nrepl        {:port 3333}
 :builds {:app {:target :browser
                :output-dir "public/js"
                :modules {:main {:entries [hello-shadow-cljs.core]}}}}}

Then I run shadow-cljs watch app with the following output:

shadow-cljs - config: ~/hello-shadow-cljs/shadow-cljs.edn  cli version: 2.7.13  node: v8.10.0
shadow-cljs - starting ...

When I fire a fireplace command I get the following error:

Error detected while processing function <SNR>166_printop[1]..<SNR>166_opfunc[35]..fireplace#client:
line   10:

Press ENTER or type command to continue

With leiningen everything works fine

You need to use Piggieback I think

I got it working with the following configuration in shadow-cljs.edn:

{:source-paths ["src"]
 :dependencies [[cider/cider-nrepl "0.16.0-SNAPSHOT"]]
 :nrepl        {:port 3333}
 :builds {:app {:target :browser
                :output-dir "public/js"
                :assets "/assets"
                :modules {:main {:entries [hello.core]}}
                :devtools {:http-root "public"
                           :http-port 8080}}}}

The next step is to create an index.html file that loads the compiled main.js file under public/js/main.js Once main,js is loaded in a browser you can connect with piggieback using the following vim command:

:Piggieback :app

So what I was missing was that the cljs repl was not started yet, for this main.js had to be loaded which activates the repl.
