countn

countn is a simple control flow for counting callbacks.

Installation

$ npm install countn

Basic Example

Here is a example of simple async scheduling. Where we have subscribed to execute some code after all concurent tasks have finished.

var countn = require('countn')
var cb = countn(5, function(err, results) {
  console.log('results:', results) // results: { all: [ [], [], [], [], [] ] }
})

setTimeout(cb(), 300)
setTimeout(cb(), 100)
setTimeout(cb(), 500)
setTimeout(cb(), 200)
setTimeout(cb(), 400)

Named Callbacks Example

Here is a example of simple async scheduling with named callbacks, so we could easily reuse results.

var countn = require('countn')
var cb = countn(5, function(err, results) {
  console.log('first result: ', results.first) // undefined
})

setTimeout(cb('first'), 300)
setTimeout(cb('second'), 100)
setTimeout(cb('third'), 500)
setTimeout(cb('fourth'), 200)
setTimeout(cb('fifth'), 400)

What's it good for?

countn is not ment to replace any control flow library, rather as i am still counting callbacks, i just wanted a simple library for a little suggar on top of it.
