Bound

a simple way do a large amount of event bindings. Heavily inspired by backbones event bindings in views.

To Install

$ npm install node-bound

This also works with browserify.

Example Usage

Lets say you have a controller, that you want to consume some events from a common messaging system that uses events.

var emitter = new ( require( 'events' ).EventEmitter )(), // new EventEmitter()
    bound = require('node-bound');

function UserController ( data ) {
    bound( emitter, {
        'user:save' : 'handleSave', // emit.addListener( 'user:save', this.handleSave.bind( this ) );
        'user:create' : [ 'handleCreate', data.anonId ] , // support for partials
        'user:delete' : this.handleDelete // pass a function instead
    }, this );
}

UserController.prototype.handleSave = function ( ) { 
    console.log( this ); // [ Object UserController ] 
};
UserController.prototype.handleCreate = function ( partialParam ) { /* ... */ };
UserController.prototype.handleDelete = function ( ) { /* ... */ };

This will bind all the events in the given context to the right method and keep the context that is given, which is great when in the context of a constructor.

    bound( emitter, eventMethodObject, context );
// eventEmitter ^ event : method ^        ^ context of method

There is also a bunch of aliases: bound.on, bound.bind, bound.addEventListener, bound.addListener

You can also unbind events that get bound by bound.

    bound.unbind( emitter, eventMethodObject, context );

Unbinding also has aliases: bound.off, bound.unbind, bound.removeEventListener, bound.removeListener

Contributing

To contribute you will need to make sure all the test are passing. To run the test you will need mocha. Then install the dependecies.

$ npm install

Then to run the test

$ npm test
