Basic cljs nrepl setup (June 2018) using clojure tools.deps cli

README.TXT

This work nicely for node repl.

Files involved, contents see below.
1. deps.edn
2. dev/nrepl_server.clj
3. dev/user.clj

Start clojure
$ clojure -A:nrepl-server

From emacs, visit the directory, then `cider-connect`, type localhost then pick port from the list.

Then, on the cider-repl (nrepl) buffer, type (cljs-node-repl).

user> (cljs-node-repl)
To quit, type: :cljs/quit
nil
cljs.user> (console.log "hello")
hello
nil
cljs.user> 


Apart from the Emacs cider that is fully functional, we can also have 
chrome node repl at the same time. In crome, type in address bar 

chrome://inspect/#devices

There will be inspect link in the Remote Target associated with our 
cljs repl. Click on the link to open the chrome console inspector.
