This is the source for my Vert.x from CodeMash 2014. The rendered slides can be seen at http://tcrawley.org/presentations/codemash-vertx-2014/vertx.html.

The sample app is in fireside-chat/. To run it, you'll first need to install Vert.x by downloading it, unzipping it, and adding its bin/ dir to $PATH.

Since the Clojure support is in beta, you'll need to tell Vert.x how to deploy Clojure applications. Edit <vertx root>/conf/langs.properties and add:

clojure=io.vertx~lang-clojure~0.4.0:io.vertx.lang.clojure.ClojureVerticleFactory
.clj=clojure

Then cd in to fireside-chat and run vertx run init.clj and hit http://localhost:8080 in a browser.
