MessagePortMain

MessagePortMain is the main-process-side equivalent of the DOM MessagePort object. It behaves similarly to the DOM version, with the exception that it uses the Node.js EventEmitter event system, instead of the DOM EventTarget system. This means you should use port.on('message', ...) to listen for events, instead of port.onmessage = ... or port.addEventListener('message', ...)

See the Channel Messaging API documentation for more information on using channel messaging.

MessagePortMain is an [EventEmitter][event-emitter].

  • message any
  • transfer MessagePortMain[] (optional)

  • messageEvent Object
    • data any
    • ports MessagePortMain[]
