Tiny event emitter with asynhronous support
Zeroin

Zeroin is a tiny functional event emitter made for the browser and 100% compatible with Node's EventEmitter .

Functional: methods don't rely on this Compatible: exact same API than Nodejs event emitters Asynchronous: create promises from a listener Useful: use the wildcard "*" to listens for all events Small: weighs less than 800 bytes gzipped

Zeroin has no dependencies and works in all mainstream browsers, included IE9+.

Usage

Basic API.

const zeroin = require('zeroin') // create new event emitter const emitter = zeroin() // listen to an event var handler = value => console.log(value) emitter.on('hello', handler) // listen to an event once emitter.once('hello', handler) // listen to all events emitter.on('*', (type, value) => console.log(type, value)) // emit an event emitter.emit('hello', 'world') // remove all listeners for a given type emitter.off('hello') // remove specific listener emitter.off('hello', handler) // remove all listeners emitter.off()

What makes zeroin special.

const emitter = {} // mixin object with zeroin API zeroin(emitter) // listen to an event and pass all the values associated to it emitter.on('hello', (...values) => console.log(...values)) // prepend listener with .on or .once emitter.on('hello', () => console.log('do something'), true) emitter.once('hello', () => console.log('do something'), true) // promises can be created from .on or .once emitter.on('hello').then((...values) => console.log(...values)) emitter.once('hello').then((...values) => console.log(...values)) // emit an event and pass multiple values emitter.emit('hello', 'world', 'universe') Installation npm install zeroin --save
