Figwheel and cljs-repl?

[au-phiware]

Is it possible to run figwheel-sidecar.repl-api/cljs-repl from redl? What can be done to make this work? Here's what I've tried:

1. Running cljs-repl from the :Repl buffer.

user=> (figwheel-sidecar.repl-api/fig-status)
Figwheel System Status

java.lang.Exception: Failed to launch Figwheel CLJS REPL: nREPL connection found but unable to load piggieback.
This is commonly caused by
 A) not providing piggieback as a dependency and/or
 B) not adding piggieback middleware into your nrepl middleware chain.

2. Running :Piggieback (figwheel-sidecar.repl-api/repl-env) and then the above (same result).

The cpp et. al. commands don't seem to work either:

Note that running lein repl :connect and then cljs-repl works just fine.

Any ideas?

I'm sorry, but I'm not a user of figwheel.

My guess is that the code on this line which sets up the REPL doesn't work on figwheel. I know that Redl itself uses JVM features to enable the interactive pausing while debugging, so that's probably part of what makes it fail.

I'd be happy to accept/shepherd a PR to address this!
