stream-composer

Modern stream composer

``
npm install stream-composer
`

Supports composing and pipelining multiple streams into a single streamx stream.

Usage

` js
const Composer = require('stream-composer')

// Make a duplex stream out of a read and write stream
const stream = new Composer()

stream.setReadable(someReadableStream) // set readable side
stream.setWritable(someWritableStream) // set writable side

// reads, read from the readable stream
stream.on('data', function (data) {
// data is from someReadableStream
})

// writes, write to the writable stream
stream.write(data)
`

API

#### stream = new Composer([options])

Make a new composer. Optionally pass the writable stream and readable stream in the constructor.
Options are forwarded to streamx.

#### stream.setReadable(readableStream)

Set the readable stream. If you pass null the readable stream will be set to an empty stream for you.

#### stream.setWritable(writableStream)

Set the writable stream. If you pass null the writable stream will be set to an empty stream for you.

#### stream.setPipeline(...pipelineStreams)

Set the stream to a pipeline. Writing to the outer stream writes to the first stream in the pipeline
and reading from the outer stream, reads from the last stream in the pipeline.

#### stream = Composer.pipeline(...pipelineStreams)

Helper for making a composer stream and setting the pipeline in one go.

#### stream = Composer.duplexer(writableStream, readableStream)`

Helper for making a composer stream and setting the writable and readable stream in one go.
