cljslein

Simplest Clojurescript demonstration project as possible with Leiningen2, nrepl, piggieback.

Not trying to bring in cljsbuild yet.

Folders structure

clojure source files root folder

src/clj/compile.clj : namespace with 'dev function to compile src/cljs/piggieback_browser.cljs to target/war/js/piggieback_browser.js
src/clj/cljsrepl_client.clj : namespace with function 'start to start the cljs repl client listening on port 9000, and serving static content for folders resources/public/ and target/war/

clojurescript source files root folder

src/cljs/piggieback_browser.cljs : clojurescript namespace bootstrapping a connection to port 9000 to serve as the javascript evaluation environment

static resources to be served by the http server. Resources right under resources/public will be mapped to their name at the root of the server URL

resources/public/hello-dev.html : dev entry point of our single-page application. Will be reached through http://localhost:9000/hello-dev.html during development once the repl client will be manually started

pre-requisite: lein2 preview9 of higher installed and setup in $PATH

Start an nrepl server and command line client:

cd /path/to/cljslein
lein repl

The first time, and everytime the target/ folder is cleaned up, recompile src/cljs/piggieback_browser.cljs to target/war/js/piggieback_browser.js:

(require 'compile)
(compile/dev)

Start the RPL part of the clojurescript REPL from the Clojure REPL:

(require '[cljsrepl-client :as rpl])
(rpl/start)

Back in the rpl, try to evaluate something:
