reduplexer

Another Stream2 duplexer

reduplexer(writable, readable, options)

Takes a Writable stream and a Readable stream and makes them appear as a Duplex stream. Heavily inspired by duplexer but using Stream2 with a bundled readable-stream.

It is assumed that the two streams are connected to each other in some way.

var cp        = require('child_process')
  , duplexer  = require('reduplexer')
  , grep      = cp.exec('grep Stream')
 
duplexer(grep.stdin, grep.stdout, { objectMode: true })

npm install reduplexer --save


Create a Duplex stream based on writable and readable using the given options. writable and readable can be null, and in that case they can be 'hooked' later.


Hooks a Writable stream. It will throw if a Writable is already hooked.


Hooks a Readable stream. It will throw if a Readable stream is already hooked.


Shortcut for:

duplex.hookWritable(writable)
duplex.hookReadable(readable)

But it will not throw if any of the two are missing.
