wongchat

Yet another chat app.

A chat app example combining clojure, clojurescript, rabbitmq, postgresql, rum, and oauth.

HTTP Sessions stored in redis.

This has now been refactored to work using components + system.

Check it out!

Development

Open a terminal and type lein repl to start a Clojure REPL (interactive prompt).

In the REPL, type

(run)
(browser-repl)

The call to (run) starts the Figwheel server at port 3449, which takes care of live reloading ClojureScript code and CSS. Figwheel's server will also act as your app server, so requests are correctly forwarded to the http-handler you define.

Running (browser-repl) starts the Weasel REPL server, and drops you into a ClojureScript REPL. Evaluating expressions here will only work once you've loaded the page, so the browser can connect to Weasel.

When you see the line Successfully compiled "resources/public/app.js" in 21.36 seconds., you're ready to go. Browse to http://localhost:3449 and enjoy.

Attention: It is not needed to run lein figwheel separately. Instead we launch Figwheel directly from the REPL
