MessageEvent-stream

Wrap a MessageEvent emiter object as a Node.js stream

Wrap a MessageEvent
emiter object as a Node.js Duplex stream.
This includes Server-sent events, Web sockets, Cross-document messaging
(postMessage()), Channel messaging, Cross-worker/document messaging (including
Service Workers), Broadcast channels and WebRTC data channels. In case the
MessageEvent emitter object is not writeable (like Server-sent events), it
will create a Readable stream instead.

This module was inspired by https://github.com/maxogden/websocket-stream and
https://github.com/DmitryMyadzelets/slip-stream/blob/master/tests/ws-stream.js,
and based on https://github.com/piranna/ws-backpressure.

Install

``
npm install messageevent-stream
`

API

- ws: MessageEvent object to be wrapped
- options: options passed to the parent Duplex or Readable stream class
constructor
- closeOnFinish: flag to emit close event after the writable stream emits
the finish event

By default, the returned stream will inherit from Readable class. If the
wrapped MessageEvent emitter object is writable (has a send() or
postMessage() method), then a Duplex` stream object will be returned instead.
