@tshemsedinov, hi!
when i practiced with clusters, i faced with es6 modules problem
there is a peace of code (i taked your code, maked it more simple and placed to one file)
(use node 18.12.1)
// import cluster from 'node:cluster';
const cluster = require('node:cluster');
if(cluster.isPrimary) {
console.log('Started master:', process.pid);
const worker = cluster.fork();
console.log('Started worker:', worker.process.pid);
console.log('sending message from server')
worker.send('hello from server');
worker.on('message', (message) => {
console.log('message from worker', worker.process.pid, message);
process.exit(0);
});
setTimeout(() => process.exit(1), 5000);
}
if(cluster.isWorker) {
console.log('Worker is ready ', process.pid, cluster.worker.id);
process.on('message', (message) => {
console.log('message from server ', process.pid, message);
process.send('hello from worker');
});
}when i use commonJS, it's worked fine. but if i use es6 modules - it doesn't work as i expect
here es6 module console output:
// Started master: 2468
// Started worker: 10064
// sending message from server
// Worker is ready 10064 1and commonJS console output
// Started master: 2388
// Started worker: 12760
// sending message from server
// Worker is ready 12760 1
// message from server 12760 hello from server
// message from worker 12760 hello from workeri think it happened because new worker process created asynchronously when i use es6 modules. and i need wait for worker message to make sure, that i can send messages to this worker.
i saw issues (like this) with this problem in node, and i want to know your opinion. is there another simpler solutions for this problem?
thank you in advance!
