1.1.7 • Public • Published

Async eventer Travis CI

A tiny library with asynchronous Promise-based implementation of events dispatching and handling.

This library works in Node and in Browser environments (UMD) and is optimized for very small size (under 1000 bytes raw, under 500 bytes gz).

How to install

npm install async-eventer

How to use

Node.js:

var Eventer = require('async-eventer')
 
var instance = Eventer();
// Do stuff

Browser:

requirejs(['async-eventer'], function (Eventer) {
    var instance = Eventer();
    // Do stuff
})

API

Eventer.on(event: string, callback: Function) : Eventer

Register event handler.

Eventer.once(event: string, callback: Function) : Eventer

Register one-time event handler (just on() + off() under the hood).

Eventer.off(event: string[, callback: Function]) : Eventer

Unregister event handler.

Eventer.fire(event: string, ...param) : Promise

Dispatch an event with arbitrary number of parameters.

tests/index.ls contains usage examples.
