Hey guys,
This is an interesting thread, as I was playing around with Clojurescript.
But I also had a hard time setting up a browser-connected repl. I wanted to
do this from a raw leiningen2 project. I finally got it working and thought
I would put this up as a reference to anyone wanting to do the same thing.
I started from a raw lein2 project.clj file, added noir and clojurescript
as dependencies, and got a browser-connected repl. This is the process I
used.
# create project and setup directory structure
lein.2 new foojs
cd foojs
mkdir -p public/{javascript,templ/cljs}
# I manually add noir and clojurescript as dependencies.
curl http://pastebin.com/raw.php?i=cmRA7jjj > project.clj
# this core.clj i) uses noir and ii) uses a custom middleware to wrap and
send files in the public/ directory
curl http://pastebin.com/raw.php?i=b6mcjY2C > src/foojs/core.clj
# the result foo.js gets loaded into the index.html, and connects the
client to the cljs repl . replace <host-url> with yours
curl http://pastebin.com/raw.php?i=Mg6vd5Mq > public/templ/cljs/foo.cljs
# pulls in i) google closure and ii) foo.js, which connects the client to
the cljs repl
curl http://pastebin.com/raw.php?i=t73k12DM > public/index.html
# I also use lein-cljsbuild to auto compile .cljs files. There are other
options like i) lein-clojurescript and ii) noir-cljs, which I haven't tried
yet
lein cljsbuild once
# Now i) start the repl, ii) start jetty in noir, and iii) fire up the cljs
repl, waiting for a browser connection
lein.2 repl
=> (require 'foojs.core)
=> (foojs.core/-main)
Starting server...
=> (require '[cljs.repl :as repl])
=> (require '[cljs.repl.browser :as browser])
=> (def env (browser/repl-env :port 9000))
=> (repl/repl env)
"Type: " :cljs/quit " to quit"
ClojureScript:cljs.user> #_=> ;; use your browser here, to open http://
<host-url>:8080
ClojureScript:cljs.user> #_=> (js/alert "I am an evil side-effect")
