send
fun send(message: Serializable, callback: (<Error class: unknown class>?) -> Unit = definedExternally): Boolean(source)
Send a message to a worker or primary, optionally with a handle.
In the primary, this sends a message to a specific worker. It is identical to ChildProcess.send().
In a worker, this sends a message to the primary. It is identical to process.send().
This example will echo back all messages from the primary:
if (cluster.isPrimary) {
const worker = cluster.fork();
worker.send('hi there');
} else if (cluster.isWorker) {
process.on('message', (msg) => {
process.send(msg);
});
