tiny-emitter

A tiny (less than 1k) event emitter library.

Install

npm

npm install tiny-emitter --save

Usage

var Emitter = require('tiny-emitter');
var emitter = new Emitter();

emitter.on('some-event', function (arg1, arg2, arg3) {
 //
});

emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');

Alternatively, you can skip the initialization step by requiring tiny-emitter/instance instead. This pulls in an already initialized emitter.

var emitter = require('tiny-emitter/instance');

emitter.on('some-event', function (arg1, arg2, arg3) {
 //
});

emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');
