How can I handle errors in a Node.js cluster?
An example of an AI chatbot conversation about error handling in Node.js clusters.
How can I handle errors in a Node.js cluster?
In a Node.js cluster, you can handle errors by listening to the 'exit' event on worker processes. When a worker crashes, you can restart it.
What if I want to log the errors before restarting the worker?
You can use the 'uncaughtException' event to log errors. Make sure to implement a logging mechanism before the worker exits.
Is there a way to gracefully shut down the cluster?
Yes, you can listen for termination signals like SIGINT and SIGTERM, and then close the workers gracefully before exiting.
Can I use a library to help with error handling?
Absolutely! Libraries like 'pm2' can manage your Node.js processes and handle errors more effectively.
