    callback-count Build Status

    Count callbacks before continuing, tiny control flow helper, allows dynamic counting.

    Flow control

    var callbackCount = require('callback-count');
    var counter = callbackCount(done);
     
    setTimeout(counter.inc().next, 100);
    setTimeout(counter.inc().next, 100);
     
    function done (err) {
      console.log('finished.');
    }

    .inc() allows you to dynamically update the number of callbacks you are expecting.

    var callbackCount = require('callback-count');
    var counter = callbackCount(done);
     
    counter.inc().inc().inc();
    counter.next().next().next();
     
    function done (err) {
      console.log('finished.');
    }

    The constructor can take an initial value for the count expected

    var callbackCount = require('callback-count');
    var counter = callbackCount(3, done);
     
    counter.next().next().next();
     
    function done (err) {
      console.log('finished.');
    }

    .next() decrements the count and callsback when the count has reached 0

    var counter = createCounter(3, done);
     
    counter.next().next().next();
     
    function done (err) {
      console.log(counter.count); // 0
      console.log('finished.');
    }

    if .next() receives an error it will callback immediately

    var counter = createCounter(3, done);
     
    counter.next(new Error('boom'));
     
    function done (err) {
      console.log(err.message); // boom
    }
