| 1 | # async-each
|
| 2 |
|
| 3 | No-bullshit, ultra-simple, 40-lines-of-code async parallel forEach function for JavaScript.
|
| 4 |
|
| 5 | We don't need junky 30K async libs. Really.
|
| 6 |
|
| 7 | For browsers and node.js.
|
| 8 |
|
| 9 | ## Usage
|
| 10 |
|
| 11 | `npm install async-each` if you're using NPM.
|
| 12 |
|
| 13 | For browsers, just include async-each before your scripts and use global variable `asyncEach`
|
| 14 |
|
| 15 | * `each(array, iterator, callback)` — `Array`, `Function`, `(optional) Function`
|
| 16 | * `iterator(item, next)` receives current item and a callback that will mark the item as done. `next` callback receives optional `error, transformedItem` arguments.
|
| 17 | * `callback(error, transformedArray)` optionally receives first error and transformed result `Array`.
|
| 18 |
|
| 19 | ```javascript
|
| 20 | var each = require('async-each');
|
| 21 | each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
|
| 22 | if (error) console.error(error);
|
| 23 | console.log('Contents for a, b and c:', contents);
|
| 24 | });
|
| 25 |
|
| 26 | asyncEach(list, fn, callback); // use global var in browser
|
| 27 | ```
