# flush-write-stream

A write stream constructor that supports a flush function that is called before `finish` is emitted

```

npm install flush-write-stream

```

[![build status](http://img.shields.io/travis/mafintosh/flush-write-stream.svg?style=flat)](http://travis-ci.org/mafintosh/flush-write-stream)

## Usage

``` js

var writer = require('flush-write-stream')

var ws = writer(write, flush)

ws.on('finish', function () {

  console.log('finished')

})

ws.write('hello')

ws.write('world')

ws.end()

function write (data, enc, cb) {

  // i am your normal ._write method

  console.log('writing', data.toString())

  cb()

}

function flush (cb) {

  // i am called before finish is emitted

  setTimeout(cb, 1000) // wait 1 sec

}

```

If you run the above it will produce the following output

```

writing hello

writing world

(nothing happens for 1 sec)

finished

```

## API

#### `var ws = writer([options], write, [flush])`

Create a new writable stream. Options are forwarded to the stream constructor.

#### `var ws = writer.obj([options], write, [flush])`

Same as the above except `objectMode` is set to `true` per default.
