README.md

cloneable-readable

Clone a Readable stream, safely.

'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.
