This Node application perioducally receives JSON data from another web application, and serves it to clients connected to it.

Install ZMQ first

brew install zeromq

Alternatively: http://zeromq.org/intro:get-the-software

sudo npm install
node --harmony server.js

Module versions might be old when you install this application, so especially if you get node-gyp compilation errors after installing modules, try updating module versions of related packages on package.json

Please see node-fetcher and node-dataprovider implementations too, all three applications work together - although not necessarily.

1. A client connects to the application. ie. ws://node-websocket/some-key
2. App checks if it has some-key's data on memory
3. If some-key's data is on memory already, it serves it to connected client
4. If some-key's data is not found, then requests it with via a socket from a specific server, ie. node-fetcher
5. Waits to receive data for some-key, over a socket. When data is received, transmits it to clients who are connected via some-key.

Go to localhost:5000/?test1 for a demo

When you have all three applications, you should start node-socketio as:

PORT=5000 node --harmony server.js
