Package Exports

cloneable-readable
cloneable-readable/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cloneable-readable) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
