Provides a ClojureScript REPL running on Node.JS.
You must have Node version 0.8.x or higher installed.
To setup the Leiningen plugin, add this to your project.clj
or
~/.lein/profiles.clj
:
:plugins [[org.bodil/lein-noderepl "0.1.10"]]
Then, start the REPL like this:
$ lein trampoline noderepl
Add the following dependency to your project.clj
:
[org.bodil/cljs-noderepl "0.1.10"]
To launch the REPL the hard way, run lein repl
and enter the following:
(require '[cljs.repl :as repl] '[cljs.repl.node :as node])
(repl/repl (node/repl-env))
The REPL is connected to a live Node process running a sandboxed environment, which provides all of Node's available global variables.
As an example, here's the standard Node hello world, in REPL ready ClojureScript:
(let [http (js/require "http")
handler (fn [req res] (.end res "Hello sailor!"))
server (.createServer http handler)]
(.listen server 1337))
If you have rlwrap installed, the following provides basic readline and paren matching support:
rlwrap -r -m -q '\"' -b "(){}[],^%3@\";:'" lein trampoline noderepl
You can get cljs-noderepl running on an nREPL server through Piggieback, though it's a bit fiddly. Here's how.
Add the cljs-noderepl dependency to your project.clj
(it will bring
in Piggieback transitively):
[org.bodil/cljs-noderepl "0.1.10"]
You may want to add this dependency to your :dev
profile so it's not
carried along when you deploy your library/application.
Then, add the Piggieback nREPL middleware, also in project.clj
:
:repl-options {:nrepl-middleware [cemerick.piggieback/wrap-cljs-repl]}
Now, launch nREPL through Leiningen as usual - lein repl
- and
connect to it from wherever you prefer. You'll need to start the
ClojureScript REPL manually once you have a Clojure REPL prompt:
user=> (require '[cljs.repl.node :as node])
user=> (node/run-node-nrepl)
