Messaging in browsers? Carl and Richard talk to Derick Bailey about messaging patterns in Javascript. Yes, browsers always use messages, that's what HTTP is about - but there are messages, and there are messages. Derick talks about using the publish/subscribe pattern with RabbitMQ to build a highly scalable system. These are patterns that are popular outside of the web, but the modern web can do anything any other system can do - so it's time to put these messaging patterns to work in your web applications!
