## Usage

```javascript
const concat = require('async-concat-stream')
```

### concat(opts = {})

Creates a writable [concat-stream]. The `promise` property of the returned stream will be resolved when all of the data has been written to the stream.

Parameters:
* `opts` - concat-stream options

Returns: `Writable` - writable stream from concat-stream with `promise` property

Usage:
```javascript
let writable = concat()
readable.pipe(writable)
let data = await writable.promise // via ES7 async
```

### concat.from(readable, opts = {})

Convenience method to read from the specified readable stream. Also handles errors from the readable stream.

Parameters:
* `readable` - `Readable`, The readable stream
* `opts` - concat-stream options
Returns: `Promise` - resolves with the data from concat-stream

Usage:
```javascript
let data = await concat.from(readable) // via ES7 async
```

## Why make this when there are ~2 others?

I like to avoid promise modules and unnecessarily adding stuff to and hybridizing promises.
