Nodule: A Pub-Sub Key-Value Store in Node.js

Features

  • Get and set UTF-8 keys and values.
  • Keyspaces allow you to separate your keys without awkward naming conventions. For example, create a 'users' keyspace with a key per ID, rather than having a bunch of "users:{id}" keys.
  • Subscribe to keys by Regex pattern, and receive a data push when the key is modified by another client.
  • Client library written in Ruby.

Installation and Execution

  1. Install Node.js from http://nodejs.org
  2. Clone this git repository.
  3. $ node nodule.js

Examples

Set and Get

n = Nodule::Client.new
n.set('global', 'a_key', 'the_value')
n.get('global', 'a_key') # returns "the value"

PubSub

Nodule.subscription do
  subscribe('global', '.*') { |space, key, value| puts "#{key}:#{value}" } # subscribe to all keys in the 'global' keyspace
end

Then when another client writes the value 'bar' to the key 'foo' in the 'global' keyspace, your subscription will process the block and output "foo:bar".
