|
|
|
|
## 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.
