    API

    #sendmessage(childprocess, message);

    Send a cross process message. If a process is not child process, this will just call process.emit('message', message) instead.

    • childprocess: child process instance
    • message: the message need to send
    sendmessage(process, {hello: 'this is a message to master'});

    You can switch to process.emit('message', message) using process.env.SENDMESSAGE_ONE_PROCESS
