This is a purely in-browser demo of Riak 2.0's sets datatype. The application code uses React.js and jquery.
To get started, make a 5-node devrel cluster of the 2.0 preview using these instructions. After your cluster is built, make a bucket-type for sets:
cd dev/dev1
bin/riak-admin bucket-type create sets '{"props":{"datatype":"set","allow_mult":true}}'
bin/riak-admin bucket-type activate sets
umask 022 for system-shared librarieswx:demo() on OS X 10.9.2 with wxWidgets 3.0.0 is still unstable, though observer:start() is more stable.brew install wxmac --disable-monolithic will do. See http://erlang.org/pipermail/erlang-questions/2014-February/077952.html.
