pull-handshake

pull-handshake

Create handshakes for binary protocols with pull streams.

Example

var stream = handshake()
var shake = stream.handshake

// Pull some amount of data out of the stream
shake.read(32, function (err, data) {

  // Write a response...
  shake.write(new Buffer('hello there'))

  shake.read(32, function (err, data) {
    // Get a confirmation,
    // and then attach the application
    var stream = createApplicationStream()

    pull(stream, shake.rest(), stream)
    // shake.rest() returns a duplex binary stream.
  })
})


// shake is itself a duplex pull-stream.
pull(shake, stream, shake)
