childprocess-messageport

Turns ChildProcess IPC into MessagePort.

Background

Instead of learning/using different API for different communication channels, we should unite them into a single interface pattern, either MessagePort or WebSocket.

How to use

const childProcess = ChildProcess.fork('echo.js');
const messagePort = new ChildProcessMessagePort(childProcess);
 
messagePort.onmessage = event => {
  // Could be either a string or Buffer
  console.log(event.data);
};
 
messagePort.postMessage('Hello, World!');

Instead of subscribing to onmessage, you can also subscribe using on('message', handler).

If the underlying childProcess.send is failed, an error event will be emitted.
