beforeEvent
BeforeEvent is an simple way to handle events before the trigger are called!
You can just simple call beforeEvent in your constructor and this is all you need!
var utils = require('util');
var BeforeEvent = require('before-event');
var EventEmitter = require('events').EventEmitter;
var MyEmitter = function(){
EventEmitter.call(this);
BeforeEvent(this);
};
utils.inherits(MyEmitter, EventEmitter);
module.exports = MyEmitter;
After you implement something like the code above you can now handle every event just adding "before" before the event.
Like this:
var MyEmitter = require('./myEmitter');
var myEmitter = new MyEmitter();
myEmitter.on('beforeHello', function(msg){
console.log(msg); //"Hello World!";
});
myEmitter.on('hello', function(msg){
console.log(msg); //"Hello World!";
});
myEmitter.emit('hello', 'Hello World!');
Enjoy it!
