async-each

No-bullshit, ultra-simple, 35-lines-of-code async parallel forEach function for JavaScript.

We don't need junky 30K async libs. Really.

For browsers and node.js.

Installation

  • Just include async-each before your scripts.
  • npm install async-each if you’re using node.js.
  • component install paulmillr/async-each if you’re using component(1).
  • bower install async-each if you’re using Twitter Bower.

Usage

  • each(array, eachFunction, optionalCallback);
  • optionalCallback optionally receives error and transformed result Array (you can transform items with eachFunction)

Node.js:

var each = require('async-each');
each(['a', 'b', 'c'], fs.readFile, function(error, contents) {
  if (error) console.error(error);
  console.log('Contents for a, b and c:', contents);
});

Browser:

// component(1)
var each = require('async-each');
each(list, fn, callback);

// Default:
window.asyncEach(list, fn, callback);
