Package Exports

events-to-array

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (events-to-array) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

events-to-array

Put a bunch of emitted events in an array, for testing.

USAGE

var assert = require('assert')
var EE = require('events')
var etoa = require('events-to-array')
var emitter = new EE()
var array = etoa(emitter)

emitter.emit('foo', 1, 2, 3)
emitter.emit('bar', { x: 1 })

// nested events get tracked as well
var subemit = new EE()
emitter.emit('sub', subemit)
subemit.emit('childEvent', { some: 'data' })
subemit.emit('anotherone', { some: 'data' }, 'many', 'args')

// CAVEAT!
emitter.emit('blaz', 'blorrg')
subemit.emit('order', 'not', 'preserved between child and parent')

// check out the array whenever
assert.deepEqual(array,
[ [ 'foo', 1, 2, 3 ],
  [ 'bar', { x: 1 } ],
  [ 'sub',
    [ [ 'childEvent', { some: 'data' } ],
      [ 'anotherone', { some: 'data' }, 'many', 'args' ],
      [ 'order', 'not', 'preserved between child and parent' ] ] ],
  [ 'blaz', 'blorrg' ] ])

`eventsToArray(emitter, [ignoreList])`

Returns an array with all the events emitted by the emitter.

It's your responsibility to know when to check it for the events that you expect.
