Node.js Cluster Module


  • const cluster = require("cluster")
  • cluster.fork()
  • cluster.isMaster
  • cluster.isWorker
  • cluster.schedulingPolicy
  • cluster.setupMaster(settings)
  • cluster.settings
  • cluster.worker // in worker
  • cluster.workers // in master


Note that cluster.fork() spawns a child process that begins executing the current script from the beginning, in contrast to the fork() system call in C which clones the current process and continues from the instruction after the system call in both parent and child process.

The Node.js Documentation has a more complete guide to clusters here
