# Dispatcher

This package let you make any object acting as an event dispatcher:

```javascript

import Dispatcher from 'dispatcher'

class MyApi extends Dispatcher {

  constructor () {

    super()

    this.load()

  }

  load () {

    // Loading stuff...

    this.dispatch('load', {

      message: 'Api loaded!'

    })

  }

  get (id, callback) {

    // Your api needs to be loaded in order to get data!

    // The callback passed to 'require' will be instantly called if

    // the event already happened, if not it will wait for it.

    this.require('load', () => {

      // Getting data...

      callback.call(this, data)

      this.dispatch('get', {

        data: data

      })

    })

  }

  update () {

    // Updating stuff...

    this.dispatch('update')

  }

}

var api = new Api()

api.once('load', event => alert(event.message))     // Will be called once before getting removed

api.on('update', event => alert('An update'), 5)   // Will be called 5 times before getting removed

api.on('get', function getListener(event) {         // Will be called until the listener is removed

  console.log(event.data)

})

setTimeout(() => api.off('get', getListener), 5000) // Now removed...

```
