simply-wait

Simply wait for some async things to happen.

Mostly useful for event emitters but also for when you just want super stupid simple code.

Install

    npm install --save simply-wait

Example

var simplyWait = require('simply-wait')
var EventEmitter = require('events').EventEmitter

var wait = simplyWait(function (err) {
    console.log('the deed is done!')
})

var e1 = new EventEmitter()
var e2 = new EventEmitter()

e1.on('get armor', wait())
e1.on('mount horse', wait())
e2.on('slay dragon', wait())

e1.emit('get armor')
e1.emit('mount horse')
e2.emit('slay dragon')

// console prints "the deed is done"

The final callback will receive the arguments from the last async operation. If you need the results from all the operations then its not "simply waiting" anymore so go ahead and use one of the many super elaborate async modules out there...

If you want to signal the gate:

var simplyWait = require('simply-wait')

var wait = simplyWait(function (err) {
    console.log('the deed is done!')
})

var notify = wait()

notify()

// console prints "the deed is done"
