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.
