# 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.
|
|||
|
|
|
|||
|
|
## Usage
|
|||
|
|
|
|||
|
|
* `each(array, iterator, callback);` — `Array`, `Function`, `(optional) Function`
|
|||
|
|
* `iterator(item, next)` receives current item and a callback that will mark the item as done. `next` callback receives optional `error, transformedItem` arguments.
|
|||
|
|
* `callback(error, transformedArray)` optionally receives first error and transformed result `Array`.
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
var each = require('async-each');
|
|||
|
|
each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
|
|||
|
|
if (error) console.error(error);
|
|||
|
|
console.log('Contents for a, b and c:', contents);
|
|||
|
|
});
|
|||
|
|
|
|||
|
|
// Alternatively in browser:
|
|||
|
|
asyncEach(list, fn, callback);
|
|||
|
|
```
