# after-all-results

If you have multiple async function calls that you want to run in

parallel and collect all their results in an array, this is the module

for you.

It's like [after-all](https://github.com/sorribas/after-all) with a

build in results aggregator.

[![build status](https://secure.travis-ci.org/watson/after-all-results.png)](http://travis-ci.org/watson/after-all-results)

## Installation

```

npm install after-all-results

```

## Usage

First require the module:

```javascript

var afterAll = require('after-all-results');

```

Then initialize with a callback that should be called once all the async

stuff is done:

```javascript

var next = afterAll(function (err, results) {

  // all done!

  console.log(results);

});

```

The returned `next` function is essentially just a smart

callback-generator. The after-all-results module will wait and not call

the all-done function until all the generated callbacks have been

called:

```javascript

someAsyncFunction(next());

anotherAsyncFunction(next());

```

**Note:** It is important that all `next()` calls are done on the same

tick as the inital call to `afterAll()`!

### Bonus: Inception mode

```javascript

var next = afterAll(function (err, results) {

  // results will be an array of `arg1` from below

  console.log('Done with everything!');

});

async(next(function (err, arg1, arg2) {

  console.log('Done with first call to async');

});

async(next(function (err, arg1, arg2) {

  console.log('Done with second call to async');

});

```
