async-queue-helper v0.1.4

async-queue

Extremely simple wrapper for async's .series and .parallel, because I got annoyed having to write var queue = [] everywhere...

Installation

Via NPM: npm install async-queue-helper

Usage

1. Parallel:

var fs 	  = require('fs');
var Queue = require('async-queue-helper');
var queue = new Queue();

queue.add('Read license', function(next) {
	fs.readFile('../LICENSE', { encoding: 'utf-8' }, next);
});

queue.add('Read package', function(next) {
	fs.readFile('../package.json', { encoding: 'utf-8' }, next);
});

queue.parallel(function(err, resultsObj, resultsArr) {
	if(err) {
		console.log('An error occured.');
		console.log(err);
	} else {
		console.log('resultsObj', resultsObj);
		console.log('resultsArr', resultsArr);
	}
});

2. Series:

var fs 	  = require('fs');
var Queue = require('async-queue-helper');
var queue = new Queue();

queue.add(function(next) {
	fs.readFile('../LICENSE', { encoding: 'utf-8' }, next);
});

queue.add(function(next) {
	fs.readFile('../package.json', { encoding: 'utf-8' }, next);
});

queue.series(function(err, resultsObj, resultsArr) {
	if(err) {
		console.log('An error occured.');
		console.log(err);
	} else {
		console.log('resultsObj', resultsObj);
		console.log('resultsArr', resultsArr);
	}
});

About queue.add: this method can take one or two arguments: just a function, or a name and a function. The name will be used to identify results in the resultsObj of the final callback. In first example, the LICENSE is available in resultsObj using resultsObj['Read license']. In the second example, no name is given so the license is available through resultsObj[0] or resultsArr[0].
