## README

# pull-async

create source [`pull-stream`](https://pull-stream.github.io) from async callback (more specifically, a [_continuable_](https://github.com/Raynos/continuable))

```shell
npm install --save pull-async
```

if you want to resolve multiple values, use [`pull-defer`](https://github.com/pull-stream/pull-defer).

## example

```js
const pull = require('pull-stream')
const xhr = require('xhr')

pull(
  pullAsync((cb) => {
    xhr.get('/things', cb)
  }),
  pull.log()
)
// [{...}, {...}, {...}, ...]
```

## usage

### `pullAsync = require('pull-async')`

### `source = pullAsync(continuable)`

a [_continuable_](https://github.com/Raynos/continuable) is a function that takes in a single argument: an error-first `callback`.

returns a source stream that will resolve the continuable into a single error or value, then end the stream.

## source

```js
function pullAsync (continuable) {
  var done
  return function (abort, cb) {
    if (abort) return cb(abort)
    if (done) return cb(true)
    continuable(function (err, data) {
      done = true
      cb(err, data)
    })
  }
}
```
