# flush-write-stream
A write stream constructor that supports a flush function that is called before `finish` is emitted
```
npm install flush-write-stream
```
[](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.
