Get piggieback running via vim

Goal

Have sample/core.cljs open in Vim (with fireplace) and be able to cpp at L23, or :Eval (js/alert "hi from editor via piggieback") and actually see an alert. This indicates we have a live connection and can eg. send re-frame events, look up docs, jump to definitions ... all the good repl-connected editor niceties.

Expected

cpp in vim should show a browser alert after starting Piggieback.

Observed

I seem to get a Nashorn repl, not a browser repl. (Evidence: nashorn_code_cache directory appears). Step 5 below shows in vim:

Execution error (IllegalArgumentException) at cljs.repl/fn$G (repl.cljc:116).
No implementation of method: :-repl-options of protocol: #'cljs.repl/IReplEnvOption
s found for class: nil
Prompt will show when REPL connects to evaluation environment (i.e. a REPL hosting
webpage)
Figwheel Main Controls:
          (figwheel.main/stop-builds id ...)  ;; stops Figwheel autobuilder for ids

          (figwheel.main/start-builds id ...) ;; starts autobuilder focused on ids
          (figwheel.main/reset)               ;; stops, cleans, reloads config, and
 starts autobuilder
          (figwheel.main/build-once id ...)   ;; builds source one time
          (figwheel.main/clean id ...)        ;; deletes compiled cljs target files

          (figwheel.main/status)              ;; displays current state of system
Figwheel REPL Controls:
          (figwheel.repl/conns)               ;; displays the current connections
          (figwheel.repl/focus session-name)  ;; choose which session name to focus
 on
In the cljs.user ns, controls can be called without ns ie. (conns) instead of (figw
heel.repl/conns)
    Docs: (doc function-name-here)
    Exit: :cljs/quit
 Results: Stored in vars *1, *2, *3, *e holds last exception object
Open URL http://localhost:9500
To quit, type: :cljs/quit
Press ENTER or type command to continue

Step 6 below shows in the repl terminal (not vim):

Steps to reproduce

Check out the minimal-piggieback branch
make distclean to clear build products, node modules and start fresh
make repl to start a JVM repl
Once the rebel CLI prompt is showing, type (go) to start nrepl and figwheel running
Open src/cljs/sample/core.cljs in vim w/ fireplace installed
:Piggieback (figwheel.main.api/repl-env "config/dev") ... wait for control to return
cpp on L23 or :Eval pretty much any form

Notes

I've also seen an issue where I seem to get further than this, but end up on a "Can't find react.cljs" error. I don't seem to be able to reproduce this (might have been an older piggieback or nrepl dep), but I'm guessing that somehow Figwheel or Nashorn isn't being made aware that target/public/js-out is where it can find this, since for that error I also had an out directory show up. My understanding is that that's the cljs compiler's default.

Make a bootstrap make command

Odd `out/` compiled JS

After starting the jvm prepl, figwheel, the figwheel prepl and then cljs-repl in the https://github.com/rgm/clojure-experiments/tree/master/prepl-browser experiment, I'm seeing the following files in /out:

Figwheel is correctly compiling my code, and I get a working repl connection in Vim, but the JS console is showing:

Something deep in Figwheel or Conjure is wanting some test namespaces?
