muxie

Simple directional stream multiplexer: send multiple streams over a single carrier.

Setup the muxer and pipe it to the demuxer.

Then get multiple named writable streams from the muxer, pipe data into them and the demuxer receives the named readable streams that will emit the data.

:warning: Early release, handle with care :sunglasses:

Note

• Currently there is an upper limit of 255 active streams.
• To send objects use JSON streams for simple objects, Buffo to stream all native JavaScript types, or any other object encoder of your choice.

Alternatives

I've used multiplex for some time, but had some weird decoding issues. Besides some null bytes errors the recursive decoding broke my stack when streaming large amounts of very small chunks. I couldn't find how to fix this in the more complex logic and it's dependencies.

Since I don't need duplex functionality I created muxie to mirror the same API but with a simpler (naïve?) implementation.

Todo

• Check more edge-cases
• Figure-out backpressure

Install

$ npm install muxie

Usage

var muxie = require('muxie');

// create a demuxer that will receive new streams
var demux = muxie.demuxer(function (stream, name) {
	// received a new readable stream
	// ..
});

// create muxer
var mux = muxie.muxer();

// create a named writable stream
var stream = mux.create('myStream');

// pipe data to the stream
fs.createReadStream('test/fixtures/lorem.txt').pipe(stream);

Build

Install development dependencies in your git checkout:

$ npm install

Build and run tests using grunt:

$ grunt test

See the Gruntfile.js for additional commands.
