High traffic slows down Node.js. Use the Cluster Module to fix this.
This module creates worker processes. These workers share one server port. Your app uses all CPU cores. This handles more users at once.
Start with these lines: const cluster = require('cluster'); const os = require('os'); const numCPUs = os.cpus().length;
Use this logic: if (cluster.isMaster) { // Master process code } else { // Worker process code }
Why use this?
- Faster speeds. Use all CPU cores.
- Better uptime. Other workers stay online if one fails.
- Easy scale. Add more workers as you grow.
Tips for success:
- Track worker health. Restart them if they stop.
- Balance the load. Split requests across workers.
