jMess

A simple event driven messaging framework for javascript.

EventRegistry

This is the heart of the system, it allows you to raise and hook to events while passing messages through your system.

---

hook(eventName: string, onRaise: Function): () => void

will register a delegate to be invoked upon raising the event and then return a cancelation function that can be called to remove the hook that was just registered.

---

raise(eventToRaise: string, data: Object): void

will raise an event passing the expected data along to each of the delegates registered to the event.

---

register(eventsToRegister: string/Object/string[]): void

allows you to register events, although this step may seem unnecessary i have found it very useful in diagnosing typos in event names.

---

getAvailableEvents(): string[]

allows you to see all currently registered events, this is mostly used for diagnostics.

###EventBarker### A little logging tool to allow for a console log stream of the events passing through the system. Simply tell it to

startBarking()

###LifeCycleEvents### These events give you access points to have logic run across all commands at different points in the life cycle.

##About the project##

• Our project is written in typescript but compiled to target ECMAScript v5.
• Currently depends on Underscore.js for some utilities with a terse syntax, as needed the project can be migrated off of it.
• Uses the ILogR interface for logging. Check out my ILogR project for an implementation with some jazz :D
