What is this?

hustler is a control flow library which works in browser.

Getting started

Load hustler (and jquery for convenience):

<script src="jquery.min.js"></script>
<script src="hustler.min.js"></script>

Register actions:

hustler.on('collect', function () {
  var arg1 = Number($('#arg1').val()), arg2 = Number($('#arg2').val());
  return { arg1: arg1, arg2: arg2 };
});

hustler.on('add', function (data) {
  return { result: (data.arg1 + data.arg2) };
});

hustler.on('output', function (data) {
  $('#result').val(data.result);
});

And then, emit an event:

$('#calc').on('click', hustler.emit('collect -> add -> output'));

To execute conditional sequence, register actions with a pattern:

hustler.on('collect', function () {
  return { value: $('#code').val() };
});

hustler.on('validate', function (data) {
  var code = data.value;
  var checkdigit = code % 10;
  // validate code
  // ...
  return { valid: (checkdigit === result) };
});

hustler.on('valid', function (data) {
  $('#info').text('code is valid.');
}, { valid: true });

hustler.on('invalid', function (data) {
  $('#info').text('code is invalid.');
}, { valid: false });

And emit a event with conditional expression:

$('#check').on('click', hustler.emit('collect -> validate -> { valid | invalid }'));
