Node child_process mute, read and handle children logs within parent

I have a parent script that spawns children nodes. 

let child = child_process.fork('foo.js', ['param1', param2])
child.on('message', data => {
//  console.log(data);
})
child.on('exit', code => {
  resolve(true)
})

Originally I thought that child.on('message') event listener catches and handles message but that's not the case here. Children simply uses parent process.stdout.write function and log stuff to parent console by default.

you can set silent to true on the child fork and listen for the stdout pipe. 

fork('./foo.js',{silent: true})
    .stdout.on('data', data => console.log(data.toString()));
