eventbroker

###About

EventBroker is wrapper of EventEmitter which provides you to have levels/namespaces of messages to listen to.

So imagine few listeners: lets start with NewYork. It is message by now but also namespace or level or whatever you like to call it. In fact some listener like that NewYork:SomeAvenue is also a message but we wrap it like it is namespace.

So if you listen to NewYork:SomeAvenue you will recieve only what goes there and if you have namespace NewYork:SomeAvenue:AvenueNumber it will not be emitted to NewYork:SomeAvenue, but if you listen to NewYork:SomeAvenue:* you will. And if you listen to NewYork:* you will get all the messages emitted to any namespace inside NewYork eg NewYork:SomeAvenue, NewYork:SomeAvenue:AvenueNumber.

###Example

Require it in your main file and create an instance (i'll put it into global)

EventBroker = require "EventBroker"

global.broker = new EventBroker

Then in any other file do something like this

global.broker.on "NewYork", (message) ->
    console.log "Listen to message to the NewYork"

global.broker.on "NewYork:CentralPark", (message) ->
    console.log "Listen to message to the CentralPark in NewYork"

global.broker.on "NewYork:StarbucksOnBroadway", (message) ->
    console.log "Listen to message to the StarbucksOnBroadway in NewYork"

global.broker.on "NewYork:CentralPark:Bench", (message) ->
    console.log "Listen to message to the Bench in CentralPark in NewYork"


global.broker.on "NewYork:*", (namespace, message) ->
    console.log "Listen to message to anyone in NewYork"

global.broker.on "London:*", (namespace, message) ->
    console.log "Listen to message to anyone in London"

global.broker.on "*", (namespace, message) ->
    console.log "Listen to any message in any namespace"

global.broker.any (namespace, message) ->
    console.log "Listen to any message in any namespace"

And then in main file

slavefile = require "./yourAnotherFile"

global.broker.emit "NewYork", "Hello NewYork and everyone in it who listens to me"
global.broker.emit "London", "Hello London and everyone in it who listens to me"
global.broker.emit "NewYork:CentralPark", "Hello guys in Central Park who listens to me"
global.broker.emit "NewYork:CentralPark:Bench", "Hello beautiful girl right there who listens to me"
