Twitter AMQP WebSocket Example

Quick experiment of going from twitter to the browser, with no polling.

It goes something like this:

Twitter Stream → Filter → RabbitMQ → AMQP → EventMachine → WebSocket → HTML5 Browser

Since it uses a fanout exchange on RabbitMQ, it allows to have multiple clients connected to the eventmachine loop and receive the same real-time updates (and hopeful it will scale).

Requirements

• Ruby
• RabbitMQ
• gem install bundler

How To

1. bundle install (first time, to install the dependencies)
2. rabbitmq-server # start rabbitmq
3. ruby twitterfeed.rb twitter_username twitter_password # start the filter
4. ruby socket.rb # on another shell

Then you can open client/index.html on a HTML5 WebSocket compatible browser (tested with Webkit nightly).

Read the code, and have fun! :)
