#Worker Utils

Starts workers with a set priority (to run background tasks or to respond in high urgency), with keepAlive option to restart failing processes. ##Installation

npm install worker_utils --save

##Usage

const
	os = require('os'),
	WorkerUtils = require('./worker_utils.js');

var workerUtils = new WorkerUtils("Background Worker");

workerUtils.setVerbose(true);

workerUtils.run('./script_that_does_a_very_long_job.js', {
	verbose : true,
	priority : 10,// (below normal); ommit it and you will get normal
	//flags : '-c', //put here the flags you want passed to node
	argv : 'this_string_is_going_to_be_passed_as_an_argument', // the arguments string for you the child process
	keepAlive : true // if the process craches, should we restart it?
	//_restartLimit : 3, // this is the default restart limit (how many times)
	//_restartDelay : 50 // this is the default restart delay (how much delay between each time)
}, function(proc, restarts){
	if(proc){
		console.log('proccess started ' + proc.pid + ' with a restart of ' + restarts);
	}else{
		console.log('proccess creation failed');
	}
});

Notes

Windows

If you wish to use custom priority on a script, you might need write access on the running dir as wmic calls sometimes write a temp batch file

Nix

Uses nice for priority handling
