Emitter

Node.js mixin, exposes on(), once(), off() in an object, allows encapsulating the emitter.

Getting Started

npm install --save @cork-labs/mixin-emitter

const emitterMixin = require('@cork-labs/mixin-emitter');

class Foobar () {
  constructor() {
    this._emitter = emitterMixin(this);
  }

  bar () {
    this._emitter.emit('baz', 101, 102);
  }
}

const foobar = new Foobar(this);
foobar.on('baz', (arg1, arg2) => {
  console.log(arg1, arg2); // 101, 102
});
