# cloneable-readable
[![Greenkeeper badge](https://badges.greenkeeper.io/mcollina/cloneable-readable.svg)](https://greenkeeper.io/)

Clone a Readable stream, safely.
```js
'use strict'
var cloneable = require('cloneable-readable')
var fs = require('fs')
var pump = require('pump')
var stream = cloneable(fs.createReadStream('./package.json'))
pump(stream.clone(), fs.createWriteStream('./out1'))
// simulate some asynchronicity
setImmediate(function () {
pump(stream, fs.createWriteStream('./out2'))
})
```
**cloneable-readable** automatically handles `objectMode: true`.
This module comes out of an healthy discussion on the 'right' way to
clone a Readable in https://github.com/gulpjs/vinyl/issues/85
and https://github.com/nodejs/readable-stream/issues/202. This is my take.
**YOU MUST PIPE ALL CLONES TO START THE FLOW**
You can also attach `'data'` and `'readable'` events to them.
## API
### cloneable(stream)
Create a `Cloneable` stream.
A Cloneable has a `clone()` method to create more clones.
All clones must be resumed/piped to start the flow.
### cloneable.isCloneable(stream)
Check if `stream` needs to be wrapped in a `Cloneable` or not.
