yakriak
A simple web-based chatroom app. Designed as a proof-of-concept for
Ben Black’s Riak training at VelocityConf 2010.
Features / Problems
- Everything is stored and served out of Riak. Take that, couchapps!
- Tested in Chrome, Safari, Firefox. Other browsers, caveat emptor.
- Remembers your login credentials via unencrypted cookies.
- Randomizes the polling interval to avoid dogpile effects.
- Uses full-bucket map-reduce, so won’t perform well at huge numbers of messages.
- Use gravatar, should you decide not to remain anonymous.
Setup
- Startup Riak locally on the standard HTTP port (8098).
- Join your local node to the cluster, if necessary.
- Run the
load.shbash script. - Visit http://127.0.0.1:8098/riak/yak/index.html

Read the source! The majority of the work is in yakriak.js, and the
map and reduce functions in the yakmr/ directory.
