open pipable streams to and from the browser, with Socket.io

branch: master
readme.markdown

BrowserStream

use Stream#pipe to send data to clients or servers.

wrap socket.io (or another web socket abstraction that gives a remote EventEmitter api) with a interface for creating streams.

DEPRECIATED

use mux-demux with shoe

I'm not gonna use or maintain this any more. If you want to use and maintain this module email me and I'll add you as owner.

install

npm install browser-stream

example

client

  var bs = require('browser-stream')(io.connect('http://localhost:3000'))
  var domnode = require('domnode') //see https://github.com/maxogden/dominode
  var opts = {options: 'pass an optional object with the createReadStream message. maybe useful!'})
  //pipe the 'whatever' stream to the dom with dominode.
  bs.createReadStream('whatever', options)
    .on('error', function (err) {
      //unexpected disconnect
      console.error(err)
    })
    .pipe(domnode('#list', '<li id="item"></li>'))

server

io = io.listen(app) //see https://github.com/LearnBoost/socket.io
var _bs = require('browser-stream')

io.sockets.on('connection', function (sock) {

  var bs = _bs(sock) 

  var whatever = new Stream() // SOME KIND OF STREAM
  bs.on('connection', function (stream, opts) {
    if(stream.name == 'whatever') 
      whatever.pipe(stream)
    //stream.options -- will be the same as `opts` from the client side!
    stream.on('error', function (err) {
      //the client has unexpectedly disconnected. tidy up!
      console.error(err)
    })
  })

}

this will connect whatever to the Dominode stream, rendering it, in the browser!

API

var _bs = require('browser-stream')

io.sockets.on('connection', function (sock) {
  var bs = _bs(sock)
  bs.on('connection', function (stream) {
    //stream is a pipable node.js `Stream` instance
  })
})

createReadStream (name, options)

open a ReadableStream from the other side. returns a ReadableStream. the other side of connection will emit a writable stream that is connected to this stream.

createWriteStream (name, options)

open a WritableStream to the other side. returns a WritableStream, the other side will emit a ReadableStream connected to this stream.

createStream (name, options)

open a Stream to the other side which is both readable and writable. returns a Stream, the other side will emit a Stream connected to this stream.

note to self, references to a class (Stream) should be capitalized, and in backticks. references to an instance should be lowercase, and not in backticks unless refuring to a specific variable in a code example.
