DEPRECATED.

Apparently this module is broken and not compatible with more recent versions of nodejs.

Do not use.

duplexer

Creates a duplex stream

Takes a writable stream and a readable stream and makes them appear as a readable writable stream.

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

var cp = require('child_process')
  , duplex = require('duplexer')
  , grep = cp.exec('grep Stream')

duplex(grep.stdin, grep.stdout)

npm install duplexer

npm test
