sails-hook-publisher
====================

[![Build Status](https://travis-ci.org/lykmapipo/sails-hook-publisher.svg?branch=master)](https://travis-ci.org/lykmapipo/sails-hook-publisher)

Kue based job publisher(producer) for sails v0.11.0+. Its a wrapper around [Kue](https://github.com/learnboost/kue) for publishing jobs by using [redis](https://github.com/antirez/redis) as a queue engine.

## Installation
```js
$ npm install --save sails-hook-publisher
```

## Usage
In sails hooks, `sails.hooks.publisher` will be available for use and it will expose:

- `queue` : a `kue` based job queue specifially for publish jobs. If you want to consume jobs you may use [sails-hook-subscriber](https://github.com/lykmapipo/sails-hook-subscriber). It is a valid `kue queue` so you can also invoke other `kue` methods from it. [See](https://github.com/LearnBoost/kue#overview)

- `create` or `createJob` : which is a proxy for `kue.create` and `kue.createJob` respectively. See [kue creating jobs for detailed explanations](https://github.com/LearnBoost/kue#creating-jobs)

## Publishing Jobs
Use `sails.hooks.publisher.create` or `sails.hooks.publisher.createJob` to publish job(s) as way you used with `kue`. You can publish jobs in any place within your sails application where `sails.hooks` is accessible and `sails.hook.publisher` is loaded and available.

Example
```js
//in AuthController.js
//in register(request,response) method

register: function(request,response){
//your codes ....

//grab publisher
var publisher = sails.hooks.publisher;

//publish send confirmation email
var job = publisher.create('email', {
title: 'Welcome'
, to: request.email,
, template: 'welcome-email'
})
.save();
}
```
*Note: The above example demostrate `sails-hook-publisher` usage in controller you can use it in your models and services too*

## Queue Events
`sails-hook-publisher` expose `queue` which is the underlying `kue queue` it use for listening for queue events. For you to listen on your job events on the queue, just add listener on the publisher `queue.on`. [see kue queue events for more explanation](https://github.com/LearnBoost/kue#queue-events)

Example:
```js
//somewhere in your codes just once
//prefered on config/bootstrap.js
//or custom hook
//or services
var publisher = sails.hooks.publisher;

//add listener on the queue
publisher
.queue
.on('job complete', function(id, jobResult) {
//your codes here
});
```

## Configuration
`sails-hook-publisher` accept application defined configuration by utilizing sails configuration api. In sails `config` directory add `config/publisher.js` and you will be able to override all the defauts configurations.

Simply, copy the below and add it to your `config/publisher.js`
```js
module.exports.publisher = {
//control activeness of publisher
//its active by default
active: true,

//default key prefix for kue in
//redis server
prefix: 'q',

//default redis configuration
redis: {
//default redis server port
port: 6379,
//default redis server host
host: '127.0.0.1'
},
//number of milliseconds
//to wait
//before shutdown publisher
shutdownDelay: 5000
}
```
