[DEPRECATED]

THIS MODULE HAS BEEN SUPERCEDED BY THE KICKTOCK MODULE.

Track the progress of sets of callbacks or Promises.

npm install --save kicks-counter

For Callbacks

To track the progress of a callback, create a counter:

const counter = require('kicks-counter')
var count = counter()

Then, for every callback you initiate, call todo before the callback - and done at the conclusion of the callback.

files.forEach(path => {
  count.todo()
  fs.readFile(path, (err, data) => {
    // Do things here
    count.done()
  })
})

You can also provide todo with a complete count before initiating the callbacks:

count.todo(files.length)
files.forEach(path => {
  fs.readFile(path, (err, data) => {
    // Do things here
    count.done()
  })
})

When the progress is complete, an 'end' event will be sent. Be sure to set up this event and start the counter.

count.on('end', () => {
  console.log('DONE')
})
count.start()

You can also track progress with the 'progress' event.

count.on('progress', () => {
  console.log(`Completed ${count.at} of ${count.total} tasks.`)
})

By default, the progress function will fire for every item. You can also use a timer if you supply a microsecond count when you create the counter.

// Progress events will occur once per second
var count = counter(1000)

For Promises

Similarly, setup the counter.

const counter = require('kicks-counter')
var count = counter()

Now add each promise to the counter.

count.todo(Promise.resolve(3))
count.todo(new Promise((resolve, reject) => {
  setTimeout(resolve, 3000, 'foo')
})

And add the events and 'start' call.

count.on('end', () => {
  console.log('DONE')
count.start()

Passing the End Event to Start()

You can also just supply an 'end' callback right to the start() method:

count.start(() => {
  console.log('DONE')
})

That's it! Enjoy.
