Windows 10 repl doesn't connect to the browser
I am trying to follow the tutorial and don't get the prompt when running the figwheel-main repl.
A) with leiningen:
lein trampoline run -m figwheel.main
B) without leiningen
clj -m figwheel.main
I get the same output:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for f

In the cljs.user ns, controls can be called without ns ie. (conns)
instead of (figwheel.repl/conns)

Part of the problem seems to come from the mix use of backslashes instead of forward slashes in the script paths.
I use git-sdk-64 as Linux replacement / bash environment. Sidenote: I am able to run a shadow-cljs hello-world with a cljs-repl in that environment.
I haven't been able to set figwheel up on my Windows 10 machine so I can't say for sure, but I strongly suspect you are on the right lines that it is related to the forward-slash / backslash difference between Windows and *nix.
If you run the following you should see the full config for the dev build which figwheel uses:
lein trampoline run -m figwheel.main -pc -b dev
where -pc is short for --print-config, and I assume your build is defined in dev.cljs.edn.
This gives some very useful information, and you should check the values of the keys :output-to and :output-dir.
The strange thing about what you have posted is the target\public\ appearing in the
{,,,
:output-dir "target\public\cljs-out"
:output-to "target\public\cljs-out\dev-main.js"
},,,
(or whatever you compiled .js file should be called, which is what the index.html is expecting.)
This may help, or perhaps provide some clue, but unless I have the environment in front of me it's very difficult to debug.
