bauer-cluster

Multi-process development library.

Installation

npm install bauer-cluster

Usage

var Cluster = require("bauer-cluster").Cluster;

var myCluster = new Cluster();

// executed when in main process
myCluster.master(function() {
  
  this === myCluster // true
  
  this.isMaster; // true
  this.isWorker; // false

  var worker = this.fork("one","two");

  worker.args; // ["one","two"]
  worker.process; // child process produced by fork
  
  worker.on("message",function(message) {
    if (message.pong) {
      worker.send({ ping: true });
    }
  });
  
  worker.send({ ping: true });

});

// executed when in child process
myCluster.worker(function(worker) {

  this === myCluster // true
  
  this.isMaster; // false
  this.isWorker; // true

  worker.args; // ["one","two"]
  worker.process; // global process object
  
  worker.on("message",function(message) {
    if (message.ping) {
      worker.send({ pong: true });
    }
  });

});

myCluster.start();
