load-balancer

Introduction

Load-balancer is a task manager for nodejs tasks.

If you have lots of independent tasks, and wish them to be done as soon as possible, you can try this tool!

Load-balancer will take full usage of CPUs.

• Create workers.
• Master send tasks to every worker.
• When a worker finishes it's task, will receive a new one from master.
• If no more tasks remain, workers will be killed.

Installation

npm i load-balancer --save

Usage

master.js

var Balancer = require('load-balancer');
...
// create a master
var master = new Balancer.Master('Master A');
// master send jobs to workers
master.send('worker.js', context, jobDetails, function(results) {
    // all jobs done here
});

worker.js

var Balancer = require('load-balancer');
...
// create a worker
var worker = new Balancer.Worker('Worker A');
// worker receive job from master
worker.receive(function(master, context, jobDetail, callback) {
    // deal with jobDetail
    callback(result);
});
