For proper coding and to run sequential asynchronous function.

Installation

$ npm install jueue

Usage

var jueue = require('jueue');

// To set jueue options.

jueue.set({
  running: true,
  pauseTime: 1000
});

// or

jueue.set("running", true);
jueue.set("pauseTime", 1000);

// No settings needed at the start. Because all settings have defaults.

// To use queue for functions.

jueue.get(
  function (e) {
    //...
    e.next();
  },
  function (e) {
    //...
    // If there is an error
    e.throw(error);
    // or complete jueue.
    e.done(); // this calls then function callback
  }
).then(function (result) {
  // Write function to manage done.
}).catch(function(err) {
  // Write function to catch error.
});

var jueue = require('jueue');
jueue.get(
  function (e) {
    //...
    e.next({ name: "test", model: "test", args: [1, 2] });
  },
  function (e) {
    //...
    e.next();
  },
  function test(e, one, two) {
    var modelValue = e.model;
    //...
  }
);
