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', ...)
