Emits-change NPM

emits-change

Plug-and-play node.js events integration to emit change events.

Installation

npm install emits-change

This package uses the node.js events API. Make sure your javascript bundler can handles importing core node modules (e.g. Browserify does this).

Usage

Calling emitsChange on an object will add node's EventEmitter, a listen, an unlisten and an emitChange function to the prototype.

import emitsChange from 'emits-change'

class Emitter {
    constructor() {
        emitsChange(this)
    }
}

let emitter = new Emitter

function doSomethingOnChange() {
    console.log('hodor')
}

emitter.listen(doSomethingOnChange)

emitter.emitChange()
// => hodor

emitter.unlisten(doSomethingOnChane)

emitter.emitChange()
// => *nothing*
