duplexer

duplexer

Creates a duplex stream

Taken from event-stream

duplex (writeStream, readStream)

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.

Example

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

duplex(grep.stdin, grep.stdout)

Similar packages

Other packages similar to duplexer

duplexify

Similar to `duplexer`, `duplexify` allows for the creation of a duplex stream from a writable and a readable stream. However, `duplexify` provides additional features such as being able to set the readable or writable part asynchronously and handling backpressure more effectively.

through2

While `through2` is a thin wrapper around Node.js streams.Transform (making it easier to create transform streams), it shares the concept of manipulating data streams with `duplexer`. Unlike `duplexer`, `through2` is more focused on transforming data rather than combining streams into a duplex stream.

pumpify

Similar to `duplexer`, `pumpify` combines streams into a single duplex stream. The difference lies in `pumpify`'s ability to combine an arbitrary number of streams into one, effectively piping data through multiple transformations in a more flexible manner than `duplexer`.
