|
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.
