## 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
```shell
npm i load-balancer --save
```
## Usage
`master.js`
```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`
```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);
});
```
