EventActions

Application level event and action emitter. Used to connect different components to each other by using common emitter for events and actions.

Events are used for notify listeners when something happens.

Actions are used to trigger things in other components.

Install

npm install event-actions

Usage

// get default EventHub instance
var actions = require('event-actions')();

// listen 'click' event from component A
actions.onEvent('A:click', function(button) {
    console.log('Component A was clicked with button ' + button);
});

// emit event
actions.emitEvent('A:click', 'Button 1');

// listen 'process' action
actions.onAction('B:process', function(a, b) {
    console.log('Processing values', a + b);
});

// emit action
actions.emitAction('B:process', 3, 5);

Namespacing

Namespacing actions and events is crusial, expecially when number of connected components grows.

In the future namespacing can be used to simplify things, such as removing all listeners from specific component.
