bulkhead-kue v0.0.1

bulkhead-kue

A Bulkhead plugin that easily integrates LearnBoost's Kue into a SailJS project.

Installation

npm install bulkhead-kue

Then, in the config/bootstrap.js file of your SailsJS project directory, replace the default cb() with:

require('bulkhead').plugins.initialize(sails, cb);

If you are using Bulkhead-Kue with Bulkhead-Test, the suite has to be lifted like this:

var Suite = require('bulkhead-test');
Suite.lift(null, function() {
	QueueService.flush(queueName);
});

Usage

To create new jobs in a queue, do the following:

var QueueService = require('bulkhead-kue');
QueueService.create('SomeQueue', 'SomeJobType', { name: 'bob' }, function(results, job) {
	// Callback that is fired when the job is processed.
	console.log(results.name) // Outputs 'bob'
	console.log(job.id) // Outputs 1
}, function(err, results) {
	// Callback that is fired when the job is saved into the queue
	console.log(results.response().name) // Outputs 'bob'
});

NOTE:

If you create a new job on a queue that has not been created yet, .create() will create the queue as well.

To get access to the queue and it's Kue methods, do the following:

QueueService.queue('SomeQueue');

To find jobs by their processing state, the search criteria should be a string:

QueueService.find('inactive', function(err, result) {
	console.log(result.response().name); // Outputs 'bob'
});

To find jobs by their ID, the search criteria should be a number:

QueueService.find(1, function(err, result) {
	console.log(result.response().name); // Outputs 'bob'
});

To find jobs by complex criteria, the search criteria should be an object:

QueueService.find({
	type: 'SomeJobType',
	state: '*',
	from: 0,
	to: -1,
	order: 'desc'
}, function(err, result) {
	console.log(result.response().name); // Outputs 'bob'
});

To process all jobs in a queue, do the following:

QueueService.process(queueName, type, null, function(job, next) {
    // Callback that is fired per job being processed
	console.log(job.data.name) // Outputs 'bob'
	next(undefined, job.data); // Moves on to the next job to process
});
